What differs is which channels each counts as a platform. Checked against their own documentation on 21 September 2026, Buffer, Hootsuite, SocialPilot and Later all cover public feeds and none reaches a WhatsApp group, Discord server or Telegram channel. *Figure — Which schedulers reach a group chat, checked on one day. Every tool here posts to mainstream feeds. The tiles show which also reach community channels. Checked 21 September 2026 (Buffer re-checked 12 October) against each product's own documentation.* ## The feature everybody has If you are searching for a tool that posts to several platforms at once, the good news is that you cannot pick wrong. Every scheduler in this category does it. Write once, tick the accounts, it goes out to all of them. That has been true for about a decade, which makes it a poor thing to compare tools on. The marketing pages still lead with it because it is the thing people search for, but nobody loses a bake-off over it. The question underneath it is more specific, and the tools answer it differently: **which channels count as a platform?** ## What each one reaches We spent a day in September 2026 checking six products against their own documentation rather than against each other's comparison pages. Every claim below links to the vendor's own page in the sources block, dated. **Buffer** connects sixteen account types: Facebook Pages and Groups, Instagram business, creator and personal, X, LinkedIn pages and profiles, Pinterest business and personal, TikTok, Google Business Profiles, Start Pages, Mastodon, YouTube Shorts, Threads and Bluesky. All public feeds. The [Buffer WhatsApp question](/vs/buffer) has its own page, checked channel by channel. **Hootsuite** publishes to Facebook, Instagram, X, LinkedIn, TikTok, YouTube, Threads and Pinterest. It also connects WhatsApp, which matters and is covered below. **SocialPilot** publishes to ten: Facebook, Instagram, X, TikTok, YouTube, LinkedIn, Pinterest, Threads, Bluesky and Google Business Profile. The [SocialPilot WhatsApp question](/vs/socialpilot) is checked on its own page. **Later** sells scheduling in units it calls social sets, each one profile from each of eight consumer platforms: Instagram, Facebook, Threads, Pinterest, TikTok, LinkedIn, YouTube and Snapchat. If you are weighing [Later social media alternatives](/vs/later), that page sets the same limit against WhatsApp groups. **Postiz**, which is open source, posts to Discord server channels, Telegram groups and channels, and Slack channels, alongside the mainstream feeds. No WhatsApp, and the [Postiz WhatsApp support question](/vs/postiz) is covered on its own page. The four commercial mainstream tools differ in the details and agree completely on the shape. A platform means a public feed you broadcast into. ## The WhatsApp answer is more interesting than it looks The obvious summary would be that Hootsuite has WhatsApp and the others do not. That summary is wrong in a way worth spelling out, because we believed it for an afternoon. Hootsuite does connect WhatsApp. What the connection does is put WhatsApp conversations into Hootsuite Inbox, where your team receives and responds to messages alongside Instagram DMs and Facebook comments. It needs a verified business account and administrator access in Meta Business Manager. Its own material describes receiving and responding, and mentions WhatsApp groups nowhere. So it is a customer-service surface, and a serious one. It is built around a person writing back to another person. Scheduling an announcement into a group chat of four hundred people is a different action, and nothing in the mainstream category does it. ## Group chat in general is not the gap The other thing we got wrong: we had assumed no mainstream scheduler posts to groups at all. Buffer posts to Facebook Groups. That is a connectable channel type in its own documentation. Postiz posts into Discord servers, Telegram groups and Slack channels, and has for years. Anyone claiming schedulers cannot reach a community has not read the documentation. The gap is narrower and more specific than that, and narrower is more useful. It is WhatsApp, which is also where an enormous number of communities live, particularly in India. That single gap is why [WhatsApp group scheduling](/whatsapp-group-scheduling) is worth treating as its own problem rather than a row on a feature grid. ## Posting the same thing everywhere is usually a mistake A caveat about the feature itself, since this is the page people land on when they want it. One post to every channel at once works when the channels are similar and the message is neutral. It stops working quickly. A LinkedIn post reads as corporate in a WhatsApp group. Image ratios differ. Character limits differ. The room that opted into a community expects a different voice from the feed that follows a brand. What is worth having is not one post everywhere. It is one plan everywhere, with the wording adjusted per channel, which is what a [content calendar](/glossary/content-calendar) is for. The tool should make the per-channel edit easy rather than make the identical blast easy. ## How to choose, given all this Three questions settle it, in this order. **Does it reach your channels?** Write down every account you post to, including the group chats, and check it against the tool's own documentation rather than its marketing page. If a channel is missing, nothing else about the tool matters. **Does the pricing model match your shape?** Per-channel pricing suits a few accounts with a lot on each. Per-seat pricing suits a small team of heavy users and punishes many people doing a little. Per-social-set assumes you grow by adding brands rather than rooms. **Do you need approvals?** If a post cannot go out until somebody signs off, that narrows the field fast, and the enterprise tools are better at it. If your answer to the first question includes a WhatsApp group, the field is small, and you can [book a demo](/contact) to watch a post land in one of yours.

The limit that matters is participants: 8 per group, per Meta's own docs, checked 22 September 2026. A WhatsApp community with hundreds of members is not what this API reaches. *Figure — What Meta's own Groups API allows, and where it stops. Read against Meta's developer documentation, checked 22 September 2026. Every note traces to the page in the sources block.* ## Meta documents an official WhatsApp Groups API On 22 September 2026 we re-checked Meta's own developer documentation for the WhatsApp Groups API, first noted the week before and held for this piece. It is real: a business with an **Official Business Account** can create and delete groups, send text, media and template messages into them, manage participants, generate invite links and pin messages, all through the Cloud API. Up to 10,000 groups per business number are allowed. The one number that decides whether this reaches a real community is further down the same page: **maximum group participants, 8.** ## Eight people is not a community The WhatsApp groups that community managers, creators and local businesses run typically hold dozens to hundreds of members, the ones people reply in, ask questions in, and stay in. An API capped at 8 participants does not touch that group. It fits a different job: a small working group, a support thread with a handful of people, a deal room. Useful, and not the same product category as "post an update to the community." A few other limits worth knowing before anyone assumes this closes a gap: - **Official Business Account only.** Meta's page states plainly that groups are "not available for WhatsApp Business app phone numbers" or Multi-solution Conversations accounts. The ordinary WhatsApp Business app a lot of small teams already use cannot touch this API at all. - **One Cloud API business per group**, and message editing and deletion are unavailable. Performance metrics are not returned for templates sent into groups, so there is no reporting layer on top of it either. - **No changelog date.** The changelog page at the same domain returned a server error on every attempt this week, so when the current version of this API shipped is not established here, only what it currently says. ## What this does not change Nothing here says anything about how any particular product connects to WhatsApp, ours included; that is a separate, unresolved question and not one this piece answers. What Meta's own documentation does settle is narrower and more useful: an 8-person API is not evidence that "official WhatsApp community posting" has arrived for groups the size communities run. If your WhatsApp group has more than 8 people in it, this API was not built with it in mind. We plan [WhatsApp group posts](/whatsapp-group-scheduling) in the same calendar as the rest of a week's content, for groups sized like the ones people run. If you're weighing that against building on an open-source base yourself, [the Postiz comparison](/vs/postiz) covers what the two products share and where they differ. If you only want to [schedule a post to a WhatsApp group](/whatsapp-group-scheduling) and not build against the API at all, that page answers it directly. For the API's full set of limits in one place, see the [glossary entry on the WhatsApp Groups API](/glossary/whatsapp-groups-api). Coming from a mainstream scheduler? The [Hootsuite alternative](/vs/hootsuite) and [Buffer alternative](/vs/buffer) pages check what each one connects against its own documentation, WhatsApp included, and so do the [SocialPilot alternative](/vs/socialpilot) and [Later alternative](/vs/later) pages. Source: https://growsocialco.com/blog/whatsapp-groups-api-participant-limit --- # Content calendar: what it is and what it has to hold A content calendar is the single dated view of what goes out, where and when, across every channel you publish to. Most scheduling tools implement it as a calendar of public feeds. If part of your audience sits in a group chat, a feed-only calendar leaves those posts to be remembered rather than planned, which is where they get missed. *Figure — What a content calendar holds, and what usually gets left out. The last three are channels every mainstream scheduler we checked on 21 September 2026 leaves off the calendar.* ## What it is A content calendar is the single dated view of what your organisation is going to publish: the post, the channel it goes to, the date and time it goes out, and what state it is currently in. The word calendar is doing real work there. The value is not the list of posts. It is seeing them laid against each other in time, so that three things going out on Tuesday and nothing for the rest of the week is visible before it happens rather than afterwards. ## What it has to hold Four fields carry most of the weight. **The channel.** Not "social" in general, but which account. The same announcement worded for LinkedIn and for a WhatsApp group is two entries, because they are two pieces of writing. **The date and time.** With a timezone, if anyone you work with is in a different one. **The state.** An idea, a draft, something approved and waiting, something already out. A calendar that only shows scheduled posts hides the work in progress, which is the part that needs managing. **The owner.** Only once more than one person is writing. Before that it is overhead. ## Where feed-only calendars quietly fail Here is the part worth checking against your own setup. Every mainstream scheduling tool builds the calendar over public feeds. Checking their own documentation on 21 September 2026: Buffer connects sixteen account types, all of them public feeds. Later sells scheduling in "social sets" defined as one profile from each of eight consumer platforms. SocialPilot publishes to ten. The three lists differ in the details and agree completely on the shape. None of them holds a WhatsApp group, a Discord server or a Telegram channel. The full six-product check, with each vendor's own documentation linked, is in [post to multiple platforms at once](/blog/post-to-multiple-platforms-at-once). So if part of your audience sits in a group chat, your calendar is not a plan for your publishing. It is a plan for the public half of it, and the other half runs on somebody remembering. The posts that get missed are almost always the ones the calendar could not see, which is an argument about tooling rather than discipline. That gap is the reason [WhatsApp group scheduling](/whatsapp-group-scheduling) is a separate problem from social media scheduling, and worth naming separately. ## A spreadsheet is a legitimate content calendar Nothing above requires software. A shared sheet with those four columns is a real content calendar and it is the right answer for a lot of people. What a sheet cannot do is publish, so it drifts: the calendar says one thing and the channels say another, and after a few weeks nobody trusts the sheet. The case for a tool is that the plan and the publishing are the same object, so they cannot disagree. That is worth something only if the tool reaches all your channels. If it reaches half of them, you have a sheet with extra steps for the other half. Source: https://growsocialco.com/glossary/content-calendar --- # WhatsApp Groups API: what it does and its 8-person cap Meta's own developer feature for creating and managing WhatsApp groups from a business account. It requires an Official Business Account and caps every group at 8 participants, per Meta's documentation. A community of dozens or hundreds runs on the consumer WhatsApp group mechanism instead, which this API does not reach. *Figure — What Meta's Groups API allows, and where it stops. Read against Meta's developer documentation, checked 22 September 2026.* ## What it is Meta documents an official **WhatsApp Groups API**, open to businesses with an **Official Business Account**: create and delete groups, send text, media and template messages into them, manage participants, generate invite links and pin messages, all through the Cloud API. A business can hold up to 10,000 groups per number. ## The limit that matters The participant cap is 8 per group. That number is the whole story: it is an API for small, business-created groups, not a way to programmatically manage a community-sized WhatsApp group that already has dozens or hundreds of members. WhatsApp Business app phone numbers are not eligible for the API at all. Only an Official Business Account qualifies. ## Why this is not community scheduling A WhatsApp community (a parents' group, a fan chat, a customer circle) usually holds far more than 8 people, and it usually already exists rather than being created fresh through an API. The Groups API does not reach either case. The full breakdown, with the API's stated limits read against what a real community-sized group needs, is in [Meta's WhatsApp Groups API caps at 8 people](/blog/whatsapp-groups-api-participant-limit). If you need to [schedule posts to a WhatsApp group](/whatsapp-group-scheduling) of real size, that is the page for the community-sized case. For where that gap sits relative to the open-source scheduler this site is built on, see [postiz alternative](/vs/postiz). Source: https://growsocialco.com/glossary/whatsapp-groups-api --- # A Buffer alternative that posts to WhatsApp groups Buffer is the cleanest mainstream scheduler in the category and the cheapest honest way to post to feeds. It connects 17 channels, none of them WhatsApp, Discord, Telegram or Slack. If your audience sits in a feed, Buffer is hard to beat on price. If it sits in a group chat, Buffer cannot reach it at all. *Figure — Where GrowSocialCo and Buffer actually differ. Buffer does post to groups. Facebook ones. That is the row people get wrong.* ## Buffer is good, and the comparison is narrower than you think Most comparison pages in this category open by explaining why the other product is bad. Buffer is not bad. It is the most straightforward scheduler anyone publishes, its pricing page has no hidden sales call in it, and it runs a public metrics page that states its own user count and revenue, which almost nobody in software does. So this page is not about whether Buffer works. It works. It is about which accounts it can connect, because that is the only thing that differs enough to change your decision. ## The channel list is the whole comparison Buffer's documentation lists every account type it connects: Facebook Pages and Facebook Groups, Instagram business, creator and personal accounts, X profiles, LinkedIn pages and profiles, Pinterest business and personal accounts, TikTok, Google Business Profiles, Start Pages, Mastodon, YouTube Shorts, Threads, Bluesky and Substack. Read that list again for what is absent. No WhatsApp. No Discord. No Telegram. No Slack. That is not an oversight on Buffer's part. It is a product decision, and a coherent one: Buffer schedules posts to public feeds, and every channel on that list is a public feed you broadcast into. Community channels are a different shape of thing, and Buffer has not gone there. Nor is Buffer unusual in this. Checking the same week, [Hootsuite](/vs/hootsuite) connects WhatsApp but only as an inbox for one-to-one messages, [SocialPilot](/vs/socialpilot) publishes to ten mainstream platforms and no group chats, and [Later](/vs/later) sells its scheduler in fixed sets of eight consumer profiles. The whole mainstream category has settled on the same answer. That agreement is either a strong signal they are right, or the gap, depending on where your audience sits. ## Buffer does post to groups, so be careful with that word Here is the claim this page will not make, because it is false: that Buffer cannot post to a group. It can. Facebook Groups are a connectable channel type in Buffer's own supported-channels documentation, and have been for years. If somebody tells you no mainstream scheduler touches group posting, they have not read the list. The difference is narrower and more specific. It is which group chats a scheduler can reach, and WhatsApp is the one that nothing in the mainstream category reaches. That gap is the entire reason [WhatsApp group scheduling](/whatsapp-group-scheduling) is the page we built before this one. ## Where Buffer connects more than we do, and where less Buffer reaches Start Pages, its own link-in-bio product, which we have no equivalent of. If a link-in-bio page is part of your setup, that is a genuine point in its favour and you would be adding a second tool to replace it. Going the other way, the channel-connect screen in GrowSocialCo carries the community channels Buffer's list does not: Discord, Slack and Telegram, plus WhatsApp groups, plus a long tail of developer and community platforms that came with the [Postiz open-source base](/vs/postiz) we build on. Neither list is longer in a way that settles it. They are aimed at different rooms. Buffer's is the list you want if you are publishing to an audience that follows you. Ours is the list you want if you are talking to an audience that joined something. ## The pricing models point at different buyers Buffer charges per channel per month, with volume discounts once you pass ten channels and a free tier covering three. That model is honest and it scales smoothly, and for a small operator it is the cheapest serious option in the category. It also tells you who Buffer is for. Per-channel pricing suits somebody with a handful of accounts and a lot to say on each. A community admin often has the opposite shape: many rooms, each needing less. Whether our pricing serves that shape better is not something this page can claim, because we do not publish a price. Book a demo and you will get a real number for your actual channel count. ## Where this page goes stale Buffer ships channels steadily. Bluesky, Threads, Mastodon and Substack are all recent additions to that list, which means the list is the part of this page most likely to age. If Buffer adds WhatsApp, the central claim here stops being true and this page changes that week. The date at the top is the last day somebody checked every claim on this page against Buffer's own documentation and pricing page, and both are linked below so you can repeat the check in five minutes. A comparison page written by the company that benefits from it is worth exactly its sources. If group chats are part of your week, the fastest way to judge this is to watch a post land in one of yours. You can [book a demo](/contact) and bring your messiest set of channels. Source: https://growsocialco.com/vs/buffer --- # A Hootsuite alternative that posts to WhatsApp groups Hootsuite connects WhatsApp, so the usual claim that it has no WhatsApp is wrong. What the connection does is put one-to-one customer messages into Hootsuite Inbox. It does not schedule a post into a WhatsApp group. If you need a shared inbox and enterprise approval workflows, Hootsuite is far more mature than we are. If you need to post into group chats, it has no path to it. *Figure — Hootsuite has WhatsApp. It does a different job.. The first two rows are both about WhatsApp, and they do not have the same answer.* ## Start with the thing most comparison pages get wrong Hootsuite supports WhatsApp. If you have read three other pages claiming it does not, they were written by somebody who checked a list from 2023 or who wanted the answer to be simpler. WhatsApp sits in Hootsuite's integrations, it connects to Hootsuite Inbox, and connecting it takes a verified business account and admin access in Meta Business Manager. We are opening with that because the rest of this page is a distinction, and a distinction is worthless if you have already caught the page overstating its case. ## What Hootsuite's WhatsApp connection does It puts WhatsApp conversations into an inbox. Hootsuite's own description is receiving and responding to WhatsApp messages alongside your other social channels. Somebody messages your business, the message arrives in Inbox next to your Instagram DMs and Facebook comments, and a person on your team answers it. Hootsuite has built real depth here, including handing a caller off from a phone menu into a WhatsApp thread. That is a customer-service surface, and a good one. It is built around a person writing back to another person. ## Answering a message and posting to a group are different jobs The thing a community admin does on a Tuesday evening is not answering messages. It is taking one announcement and putting it into eleven group chats, some on WhatsApp, some on Telegram, one on Discord, and then doing it again on Thursday. Nothing in Hootsuite does that. Its WhatsApp integration is a conversation tool, its group-chat coverage elsewhere is absent, and WhatsApp groups appear nowhere in its material. This is not a gap it is hiding. It is a product aimed somewhere else, and the somewhere else is a brand with customers writing in rather than a community that has to be reached. That is the job [WhatsApp group scheduling](/whatsapp-group-scheduling) is about, and it is the reason this product exists at all. ## The community channels are missing entirely Beyond WhatsApp, Hootsuite publishes to Facebook, Instagram, X, LinkedIn, TikTok, YouTube, Threads and Pinterest. All mainstream feeds. Discord does not appear. Telegram does not appear. Slack appears, but as a collaboration app: you can push a post into Slack to show a colleague, not publish to a Slack channel as an audience. GrowSocialCo posts to all three as destinations, which it inherited from the [Postiz open-source base](/vs/postiz) it is built on. That inheritance is worth being honest about. We did not build Discord and Telegram support. We got it, and then added the WhatsApp piece nobody else had. Hootsuite is the closest of the big four to having an answer here, and it is still not one. [Buffer](/vs/buffer) has no WhatsApp at all, [SocialPilot](/vs/socialpilot) has none either, and [Later](/vs/later) does not list a single group chat among the profiles in a social set. Hootsuite at least has the connection. It points at a different use for it. ## Per-seat pricing and who it punishes Hootsuite charges per user, per month, and the entry tier is a serious number before you have added a second person. For a marketing team of four who each spend their day in the tool, that is defensible. For a community setup it is the wrong shape entirely: the pattern there is many people each doing a little, a volunteer moderator who posts twice a week, an intern who handles one channel. Under per-seat pricing every one of those is a full-price seat, so the tool quietly pushes you to share a login, which is how audit trails die. We do not publish pricing, so this page cannot claim we are cheaper. What it can say is that per-seat is a model choice with a predictable victim, and if your team looks like that, price it carefully before committing. ## Where Hootsuite is clearly ahead Approval workflows. Custom permissions. Team reporting. Fifteen years of enterprise hardening and the compliance paperwork that comes with it. Case studies with named brands and attributed numbers, which is a higher standard of proof than most of this category manages. If a post cannot go out until a manager approves it, Hootsuite has solved that and we have not. Say that out loud when you are comparing, because it matters more than a channel list to some buyers and we would rather you picked the right tool than picked us. ## Where this page goes stale The claim most likely to age here is the one about group posting, not the one about the inbox. Meta has been widening what the WhatsApp Business platform permits, and if Hootsuite adds scheduled group posting, the distinction this whole page rests on collapses and the page changes that week. The date at the top is the last day somebody checked each claim against Hootsuite's own integrations page, inbox page and pricing page, all linked below. Go and check them. This page is written by an interested party and you should treat it that way. If group chats are the hard part of your week, the honest test is watching a post land in one. You can [book a demo](/contact) and bring your real channels. Source: https://growsocialco.com/vs/hootsuite --- # A Later alternative that posts to WhatsApp groups Later has repositioned around influencer marketing, and plain scheduling now lives at a sub-page rather than its homepage. Its scheduler covers eight mainstream profiles per social set, none of them WhatsApp, Discord or Telegram. If you run creator campaigns and need a media library, Later is well ahead of us. If you need to reach a group chat, it does not go there. *Figure — Where GrowSocialCo and Later actually differ. Later reaches a platform we do not. It is just not one your community sits in.* ## Later is not competing for this anymore Open Later's homepage and it does not offer to schedule your posts. It offers to run influencer campaigns, leads with insight and creator partnerships, and puts its numbers about influencer-driven purchases in front of you. The scheduler still exists. It has been moved to its own sub-page, and you have to go looking for it. That repositioning is the most useful fact on this page, because it tells you what Later intends to be good at now, and a company generally gets better at the thing its homepage is about. ## What the scheduler reaches Later sells scheduling in units it calls social sets. One set is one profile from each supported platform: Instagram, Facebook, Threads, Pinterest, TikTok, LinkedIn, YouTube and Snapchat. Eight profiles. Snapchat is worth pausing on, because it is the one platform in this whole comparison that Later reaches and we do not. If Snapchat matters to you, that is a real point in its favour and no amount of community-channel coverage makes up for it. What a social set does not contain: WhatsApp, Discord, Telegram, Slack. The set is a list of visual consumer feeds, which fits a product built around Instagram and grown outward from there. That absence is the category norm rather than a Later decision. [Buffer](/vs/buffer) lists no group chat among its sixteen channels, [SocialPilot](/vs/socialpilot) publishes to ten mainstream platforms and stops there, and [Hootsuite](/vs/hootsuite) connects WhatsApp for conversations instead of posts. Later is the most explicit of the four about which eight platforms you get. ## The social-set model assumes a shape Pricing by social set carries an assumption: that you want one profile per platform, and that growth means adding another brand rather than another room. A community operation grows the other way. It does not add a second Instagram. It adds a seventh WhatsApp group, then an eighth, because a new cohort started or a chapter opened in another city. There is no unit in Later's pricing that describes that, because the product was not built to. Ours is the [Postiz open-source base](/vs/postiz) with WhatsApp groups added, and it counts rooms rather than brands. Whether that maps to your setup is the actual question, and it is worth asking before either price matters. ## Scheduling as the front door Later's own repositioning created a gap we walked into deliberately. When a buyer types a plain query about scheduling posts, they want the tool to say yes on the first screen. Later now answers a campaign question first, and the plain answer is a click away. Plenty of buyers will not make that click. We kept scheduling as the front door, and then went narrower still: the first page we built was about a single job, getting a post into a [WhatsApp group](/whatsapp-group-scheduling) on a schedule. A narrower front door reaches fewer people and convinces more of them. ## Where Later is clearly ahead The media library. Creator discovery and influencer campaign management, which is a whole product we do not have any version of. Link-in-bio. Years of Instagram-specific depth around visual planning and grid preview, which you only build by being the tool photographers used first. Later also publishes case studies with named brands and hard numbers, which is a standard of proof this site cannot match yet, because we have four named early customers and no published figures at all. If your work is visual, campaign-shaped and creator-led, take Later. This page is not trying to talk you out of it. ## Where this page goes stale Later has been moving fast in one direction, and the direction is away from plain scheduling rather than toward group chats. The claim here most likely to age is not the channel list but the positioning, and if Later brings scheduling back to its front door, the section above stops being true. The date at the top is the last day somebody checked every claim on this page against Later's own scheduler page, pricing page and homepage, all linked below. Check them yourself, especially the social-set contents, since that is the part that decides whether Later reaches your audience. If your audience is in group chats, the test that settles it takes one post. You can [book a demo](/contact) and bring the rooms you run. Source: https://growsocialco.com/vs/later --- # A Postiz alternative that posts to WhatsApp groups GrowSocialCo is built on Postiz's open-source base, so the calendar, the network list and the posting workflow are close cousins. The difference that matters is WhatsApp: Postiz has no WhatsApp provider at all, and GrowSocialCo posts into WhatsApp groups. If you do not run group chats, Postiz is the simpler choice and you can host it yourself. *Figure — Where GrowSocialCo and Postiz actually differ. The second row is the one people assume differs. It does not.* ## Most of this software is the same software GrowSocialCo is a fork of Postiz. The calendar you plan in, the queue that pushes one post to several accounts, the provider code behind most of the channels: that is Postiz's work, published under the AGPL-3.0 licence, and we build on top of it. That is an odd thing to open a comparison page with, so here is why it is the first thing you should know. If you are weighing these two products, the features you would normally compare line by line are mostly shared. Comparing them on "does it have a visual calendar" would waste your afternoon. One difference decides this, and it is the one below. ## Postiz does not post to WhatsApp Not to a group, not to a contact, not at all. We checked three places on 21 September 2026, and they agree. The network list on the Postiz homepage does not include WhatsApp. The provider pages in the Postiz documentation do not include WhatsApp. The integrations directory in the Postiz source repository, which has one folder per supported provider, has no WhatsApp folder in it. There is an open feature request asking for WhatsApp channel support, filed in August 2026. Somebody else wants this too. It has not been built. Meta does document its own official Groups API for approved businesses, separately from anything Postiz or GrowSocialCo builds — its [participant limit](/blog/whatsapp-groups-api-participant-limit) is 8 per group, which is not the size of the communities either product is aimed at. ## Group chat is not the gap. WhatsApp is. This is where most comparison pages in this category would overclaim, so read this row carefully: Postiz posts into group chats. It posts to Discord server channels through a bot, to Telegram groups and channels, and to Slack channels. So does GrowSocialCo, and for the same reason, which is that we inherited that code. If somebody tells you no scheduler can post into a community, they have not looked at Postiz. The gap in this category is narrower and more specific than that. It is WhatsApp, which is also where a great many communities live, particularly in India. That gap is the whole reason [WhatsApp group scheduling](/whatsapp-group-scheduling) is the page we built first. ## What sits on top of the fork WhatsApp groups as a posting target you connect like any other channel, planned in the same calendar as your Instagram and LinkedIn posts. Template Pro, so a post comes out on-brand without opening a design tool first. An Agent that helps draft what goes out next, so the calendar does not start empty. The honest framing: these exist because a small team was running its own community channels by hand and got tired of it, not because a roadmap workshop produced them. ## The two products are aiming at different things now Postiz has spent this year pointing itself somewhere specific. It ships a separate command-line agent so that Claude, Cursor or Gemini can schedule posts for you, and its own repository describes it as an agentic scheduling tool. If you want your posting driven from a terminal by a coding agent, that is a product decision aimed straight at you, and it is not one we have made. We spent the same year on a different axis: the channels a community sits in. Both are real bets, and they are not the same bet. Which one suits you depends on whether the hard part of your week is writing the posts or reaching the people. ## Where this page goes stale Postiz ships quickly. If that WhatsApp feature request lands, the central claim on this page stops being true, and the page changes that week. The date at the top is the last day a person checked every claim here against Postiz's own site, documentation and source, and every one of those checks is linked below so you can repeat it in ten minutes. We would rather you did. A comparison page written by the company that benefits from the comparison is worth exactly as much as its sources, which is why they are all listed and dated. If WhatsApp groups are part of your week, the fastest way to judge this is to watch it post into one of yours. You can [book a demo](/contact) and bring your messiest week of channels. Source: https://growsocialco.com/vs/postiz --- # A SocialPilot alternative that posts to WhatsApp groups SocialPilot is the one big competitor that prices in rupees and speaks to Indian agencies directly, which makes it the closest comparison on cost. It publishes to ten mainstream platforms, and WhatsApp, Discord and Telegram are not among them. If you bill clients for managing their feeds, SocialPilot is built for you. If you run your own community, it cannot reach where it lives. *Figure — Where GrowSocialCo and SocialPilot actually differ. Both price for India. Only one of them reaches where an Indian community sits.* ## The closest comparison on price, and the furthest on purpose Of the big schedulers a buyer in India weighs, SocialPilot is the one that has done the obvious thing and priced in rupees. Its plans are quoted in rupees, its case studies talk about agency margin, and it does not make you convert a dollar figure in your head to work out what a year costs. That makes it the most relevant competitor on cost and, at the same time, the one aimed at a completely different person. Worth separating those two before you compare anything else. ## What SocialPilot publishes to Its own publishing page names them: Facebook, Instagram, X, TikTok, YouTube, LinkedIn, Pinterest, Threads, Bluesky and Google Business Profile. Ten mainstream platforms, and the integrations page agrees with the publishing page, which is more consistency than several rivals manage. No WhatsApp. No Discord. No Telegram. Slack does appear on the integrations page, and it is worth reading that entry carefully because the word is doing different work than you would assume. Slack is there to deliver workflow notifications to your account, so your team hears that a post went out. It is not a channel SocialPilot publishes to. We post to Slack channels as a destination, which is a different thing wearing the same logo. ## A tool for people who bill clients SocialPilot's pricing model tells you who it is for more clearly than its headline does. A flat plan fee, a set number of social accounts included, and then extra accounts and extra users added per month, each priced separately. That is agency arithmetic. You add a client, you add their accounts, your cost goes up by a predictable amount and you bill it on. The testimonials on its site say the quiet part directly, talking about managing higher volume without hurting margins. Nothing about that is a criticism. It is a well-built answer to a real business, and if that is your business, the rest of this page will not change your mind. ## The community admin is a different person The person GrowSocialCo is built for does not have clients. They have rooms. A WhatsApp group of parents, a Discord server of players, a Telegram channel of subscribers, and the same announcement that has to reach all of them by Thursday. There is no invoice at the end of it. The pressure is the copying and pasting, not the margin. SocialPilot cannot reach any of those three rooms. That is the gap [WhatsApp group scheduling](/whatsapp-group-scheduling) exists for, and the Discord and Telegram halves of it came with the [Postiz open-source base](/vs/postiz) we build on. The same holds for everyone at SocialPilot's scale. [Buffer](/vs/buffer) connects sixteen channels and none of them is a group chat, [Hootsuite](/vs/hootsuite) connects WhatsApp only as an inbox, and [Later](/vs/later) does not reach one either. Nobody selling to agencies has needed to, because an agency's clients want reach on public feeds and can measure it. ## Where its positioning weakens its own case The headline on its homepage says it is the only platform you will need. Anybody running community channels can falsify that in about four seconds, which is the risk of an absolute claim: it invites the one test that breaks it. A page that said "the only platform an agency needs for mainstream feeds" would be defensible and nearly as strong. We mention this not to score a point but because it is the exact trap this page is trying not to fall into. GrowSocialCo is not the only platform you will need either. If you want client reporting and white-label decks, we do not have them, and SocialPilot does. ## Where this page goes stale SocialPilot serves a large Indian customer base, and WhatsApp is where Indian audiences are. Of all the rivals on this site, SocialPilot is the one with the clearest commercial reason to add WhatsApp, so treat the central claim here as the one most likely to change. The date at the top is the last day somebody checked these claims against SocialPilot's own publishing, integrations and pricing pages, all three linked below. The check takes five minutes and we would rather you ran it than took our word. If your rooms are the hard part, the test that settles it is watching a post arrive in one. You can [book a demo](/contact) and bring the channels you run. Source: https://growsocialco.com/vs/socialpilot
