8 Best Postiz Alternatives for AI Agents and Social Media (2026)

The Saturday spent fixing a Temporal container instead of posting is when most people start looking for Postiz alternatives. Price rarely enters into it: the license is free, and the maintenance is the invoice. Others drive Postiz through its API and an AI agent, and want the same automation without keeping a server alive. Blotato is my top pick below for that reader if 9 platforms cover your stack, and I am the founder, so judge that entry on what its tools can reach rather than my word. You can also compare the plans yourself before reading on.

One correction before the list, because it may save you the switch entirely. The “Postiz is capped at 100 requests per hour” line repeated across this category is wrong as usually stated, and I walk through Postiz’s own documentation on it further down.

Quick Comparison: 8 Best Postiz Alternatives

Tool	Best For	Starting Price	Hosted MCP server	Key Strength
Blotato	Builders whose agent publishes to 9 platforms and answers Instagram and Facebook comments and DMs	$29/mo (20 accounts)	Yes, mcp.blotato.com/mcp (35 tools)	Publishing on 9 platforms plus Instagram and Facebook comments, DMs and DM automation behind one key
Zernio	Developers who need the widest platform and channel reach from one API	Free for 2 accounts, then $6/account/mo	Yes, mcp.zernio.com/mcp	16 social platforms plus ads, messaging and phone channels on one API key
Post Bridge	Indie builders who want a simple publishing API and MCP at one price	$39/mo (15 accounts)	Yes, www.post-bridge.com/api/mcp/mcp	MCP, REST API and an agent skill all included on the entry plan
Mixpost	Teams who want to keep self-hosting and pay once for the license	Lite free, Pro $299 one-time	Yes on Mixpost Cloud from $49/mo, cloud.mixpost.app/p/mcp, or self-run with Pro	A one-time self-hosted license with no AGPL copyleft obligation
Buffer	Creators posting to 3 channels who want the simplest possible tool	Free, then $6/channel/mo ($5 annual)	Yes, mcp.buffer.com/mcp	Over a decade of hosted publishing, with a free plan
Publer	Solo operators who want cheap, hosted bulk scheduling	Free, then $5/mo for 1 account	Business plan and up, mcp.publer.com	Bulk scheduling and a free tier, hosted by someone else
Metricool	Marketers who need detailed analytics alongside scheduling	Free, then about $20/mo annual	Yes, ai.metricool.com/mcp, any plan	Tracks up to 100 competitor profiles on its Starter plan
SocialPilot	Small agencies managing client accounts on a budget	$30/mo ($25.50 annual)	Yes, mcp.socialpilot.co/mcp	Approval workflows and client reporting at agency-friendly prices

Every hosted endpoint in that column answered an unauthenticated JSON-RPC initialize call with a 401 on 23 October 2026. That shows a live server asking for credentials, not a full test of its tools. Publer’s server lives at the root of mcp.publer.com, not at a /mcp path, which is why this post’s earlier version reported it missing.

Why People Are Looking for Postiz Alternatives

Postiz’s cloud plans start at $29 a month, and the whole draw is that you can self-host it under AGPL-3.0 for the cost of a server. I ran that break-even, maintenance included, in my Postiz pricing breakdown. The person searching for alternatives already had the cheap option and is leaving anyway.

The public issue tracker shows one recurring pain point. The open issue “Could not add provider” sat at 61 comments when I checked on 23 October 2026, most of it from self-hosters stuck at the account-connection step. Postiz’s own system requirements recommend 4 vCPU and 8 GB of RAM for a small team, plus PostgreSQL 14 or newer, Redis 6 or newer, and a Temporal stack that has been required since v2.12.0. When you host the software, a bug like the Instagram retry loop in issue #832, closed as not planned, is yours to catch. So are security patches: Postiz’s repository lists 18 security advisories published in 2026, five rated critical, and on October 24 NVD published two more that aren’t on that list, scored 9.9 and 9.6 and fixed in v2.25.3. I counted on 2 November 2026.

The newer reason is agents. Postiz now calls itself “the agentic social media scheduling platform,” and plenty of its users drive it from Claude or a script rather than the calendar. Those readers want an API and an MCP server that cover the whole job, so they get extra weight below, alongside self-hosters and dashboard users. If you are still weighing self-hosting against a managed API rather than shopping, self-hosting versus a managed API is the more useful read.

Update, 23 October 2026: On 21 October, Railway, the cloud platform Postiz Cloud ran on at the time, disclosed that an unauthorized party may have accessed some Railway customers’ encrypted environment variables, and for some of them the decrypted contents. As a precaution, Postiz’s founder took the hosted service offline for every customer later that day, then posted the next morning that it was back up. If that night is why you are reading this, my Postiz switching guide covers what to check first, including what self-hosters on Railway should rotate. Update, 2 November: Postiz has since moved its hosted service to AWS, and its founder said on October 31 that the move was done (his post).

The Postiz Rate Limit Everyone Gets Wrong

You have probably been told Postiz is “capped at 100 requests per hour.”

Here is what Postiz’s own configuration reference says about the API_LIMIT variable today, verbatim:

Per-hour limit on the public-API create-post endpoint. Defaults to 90. It is a single value for the whole instance and does not tier by plan: channel and post quotas do that instead.

Its public API docs add that Postiz Cloud runs at 100 an hour. Three corrections fall out of that.

It applies to the create-post endpoint only. Listing integrations and uploading media are not counted.

On self-hosted it is a setting you control. The default is 90, and the same reference notes that the shipped docker-compose.yaml sets it lower, at 30, and tells you to raise it if you drive Postiz from scripts. The number quoted at you as a hard limit is a line in your own config.

It does not tier by plan. Paying for Ultimate does not buy you more requests per hour.

The same API docs add that one request can carry several posts, so even the Cloud limit caps requests, not posts. So the limit is a reason to leave Postiz Cloud at most, and self-hosting already answers it by letting you raise the cap. Our Zernio vs Postiz comparison puts both rate limits in one table if you want the numbers side by side.

Best Postiz Alternatives for 2026

I ranked these for the reader most likely to be here: someone who runs social media through an API or an agent and wants the same control without a server. The three API-first picks come first, then the best way to keep self-hosting, then the hosted schedulers for readers who mostly work in a dashboard.

1. Blotato: Best for agent builders who also answer comments and DMs

Blotato gives an agent publishing on 9 platforms plus Instagram and Facebook comments and DMs through one hosted key.

Blotato is a hosted social media API and MCP server for AI agents, and it fits when its 9 platforms cover your networks. One key schedules and publishes to all 9 and answers Instagram and Facebook comments and DMs, from $29 a month for 20 accounts.

Start with what the tools can reach. Blotato’s hosted MCP server at mcp.blotato.com/mcp exposes 35 tools (counted on the connected server on 23 October 2026, matching Blotato’s tool reference). Postiz’s MCP docs list 13, and they are candid about the boundary: “There is no getComments or replyToComment exposed via MCP.” Both publish and schedule well. The gap is everything after the post goes live: reading and answering comments (blotato_list_comments, blotato_post_comment), the DM inbox (blotato_list_conversations, blotato_send_message), eight tools for creating, editing and monitoring DM automations, and analytics (blotato_get_post_analytics, blotato_list_top_posts). The same key works over REST and inside n8n or Make through official nodes, from $29 a month. AI image and video generation comes with the plan as a supporting extra.

Where it falls short is coverage. Blotato publishes to 9 platforms against Postiz’s 30-plus, so check your list for Mastodon, Discord and the other long-tail networks before you move. The engagement tools stop at Instagram and Facebook, analytics skips LinkedIn, and there is no self-hosted build. One more thing for API readers: the 7-day trial excludes the API and MCP server, and generating a key starts the paid plan.

Pros:

• 35 MCP tools reaching comments, DMs, DM automation and analytics
• Flat price per account band: $29 covers 20 accounts with no per-post fees
• Hosted, so there is no Temporal stack, no .env file and no OAuth app to register
• REST API plus official n8n and Make nodes on the same key

Cons:

• Fewer platforms than Postiz’s 30-plus
• Engagement tools cover Instagram and Facebook only, and LinkedIn has no analytics yet
• No self-hosted or free option

Pricing: Starter $29/mo (20 accounts), Creator $97/mo (40 accounts), Agency $499/mo (100 accounts). 7-day trial, cancel anytime.

Ideal for: Builders whose agent has to handle what happens after a post goes out, on the major platforms.

Bottom line: The pick if 9 platforms cover your stack and your agent has to handle the replies as well as the posts.

2. Zernio: Best for developers who need the widest reach from one API

Zernio prices its API per connected account, with the first two free.

Breadth is the whole pitch at Zernio. It publishes to 16 social platforms and sells ads, WhatsApp, SMS, calls and phone numbers behind the same key. Its rate card lists messaging on nine channels and comments and reviews on eight. Its MCP server is large too: the agents page advertises 496 tools, with a smaller set visible by default and the rest found on demand.

The pricing is the part to model before you commit. The first two accounts are free, accounts three to ten cost $6 each, and accounts 11 to 100 cost $3 each. By Zernio’s own worked examples, 10 accounts is $48 a month and 20 is $78. Sent messages past 10,000 a month are metered on top. That is cheaper than a flat plan at a handful of accounts and dearer in the middle bands, so run your real count. Our Blotato vs Zernio breakdown walks the crossover points.

“Super easy platform to connect via MCP.” (a Trustpilot reviewer)

Pros:

• 16 social platforms, plus ads, messaging and phone channels on one API key
• Comments and reviews on eight platforms and messaging on nine channels
• First two accounts free, no credit card

Cons:

• The bill moves with every account you connect
• TikTok is on neither the messaging nor the comments list
• The breadth is a lot to learn if you only need publishing

Pricing: Accounts 1-2 free, 3-10 $6/mo each, 11-100 $3/mo each, 101+ $1/mo each. 10 accounts is $48/mo by Zernio’s own example.

Ideal for: Developers building a product on top of social APIs who need the most platforms and channels.

Bottom line: The pick when reach across platforms and channels matters more to you than a bill that stays flat.

3. Post Bridge: Best for indie builders who want one simple price

Post Bridge sells an MCP server, a REST API and an agent skill on every plan.

Post Bridge is a publishing API and MCP server for AI agents from indie founder Jack Friks, with no comment or DM tools in its published tool list. It posts to 10 platforms including Google Business, and its agent page leads with “The social media API built for AI agents.” The MCP server, the REST API and an installable agent skill are all included on the entry Marketer plan, so there is no API add-on to price separately.

Its MCP tool list, as published in its own llms.txt, covers posts, accounts, media and analytics, so an agent that needs to answer the audience needs another tool beside it. For publishing and scheduling it is clean, and the price takes one line to explain. Our Post Bridge alternatives piece goes deeper on where it fits.

Pros:

• MCP, REST API and agent skill all on the entry plan
• One price for 15 accounts, with no per-post fees
• Covers Google Business alongside the usual nine

Cons:

• No comment or DM tools in its published MCP list
• Paid plans only once the 7-day trial ends
• The next step up is $99 for 99 accounts, a big jump from 15

Pricing: Marketer $39/mo (15 accounts). Operator $99/mo (99 accounts, then $1 per account). 7-day free trial.

Ideal for: Solo builders who want their agent publishing to 10 platforms at one predictable price.

Bottom line: A tidy publishing API, as long as your agent never needs to read the replies.

4. Mixpost: Best for teams who want to self-host without the copyleft strings

Mixpost is self-hosted like Postiz, but sold as a one-time license.

If you are leaving Postiz but want to keep self-hosting, Mixpost is the natural landing spot. You pay once rather than monthly, and you run it on your own server. It is a Laravel application, so the stack is lighter than Postiz’s Temporal setup, and for a lot of teams that alone is the reason to switch.

The other reason is licensing. Postiz is AGPL-3.0, a network copyleft license, which matters if you plan to modify it and offer it as a service. Mixpost’s paid license carries no copyleft obligation, though it has its own limits: the paid editions are source-available rather than open source, you may not resell the code, and running it as a SaaS needs Enterprise. On the agent side, Mixpost ships an MCP server inside your own instance, and it now sells Mixpost Cloud as well, with a hosted MCP endpoint at cloud.mixpost.app/p/mcp from the $49 Momentum plan. That makes it the one tool here you can run either way. If Mixpost itself is the thing you are replacing, these are the strongest Mixpost alternatives.

“The setup cost was real, but after that, posts just happen.” (a Reddit user in r/Host1AIBusiness, describing an AI agent driving a self-hosted Mixpost)

Pros:

• One-time license, with a perpetual fallback if you skip renewal
• Lighter stack than Postiz’s Temporal requirement
• No AGPL copyleft obligation
• MCP on self-hosted Pro and on Mixpost Cloud from $49/mo

Cons:

• Self-hosted, you still own uptime, updates and OAuth breakage
• Paid editions are source-available, and SaaS use needs Enterprise
• Smaller community than Postiz

Pricing: Lite is free. Pro is $299 one-time and Enterprise is $1,199 one-time, each with a year of updates. Mixpost Cloud starts at $29/mo, with the API and MCP from $49/mo.

Ideal for: Technical teams who want to keep the software on their own servers.

Bottom line: Your best bet for a lighter stack and a one-time license on your own server.

5. Buffer: Best for creators who only need three channels

Buffer’s free plan covers three channels with straightforward scheduling.

Buffer is the least exciting recommendation on this list and one I would still make to a specific reader. It has published posts reliably for over a decade with very little to maintain.

Credit where it is due on agents: Buffer ships an official MCP server at mcp.buffer.com/mcp, and its developer docs show create_post taking a shareNow mode, so an agent can publish, not just queue. Tools for ideas, templates, edit_post and delete_post sit beside it. The thin part is the per-channel bill underneath. We put the two MCP servers against each other in Postiz vs Buffer.

“we use buffer. It’s free for up to 3 channels and pretty reasonable for more.” (a Reddit user in r/AppBusiness)

Pros:

• Free plan for three channels
• Over a decade of reliable hosted publishing
• Official MCP server that can publish immediately or schedule

Cons:

• Per-channel pricing scales painfully
• Its inbox handles comments, with no DMs

Pricing: Free for 3 channels. Essentials $6/channel/mo ($5 annual), Team $12/channel/mo ($10 annual). From channel 11 Essentials drops to $4, and from channel 26 to $3.

Ideal for: Creators posting to a few channels who want zero maintenance and zero surprises.

Bottom line: Boring in the best way, if three channels is genuinely all you need.

6. Publer: Best for solo operators who want cheap hosted scheduling

Publer offers hosted scheduling with a free tier and low per-account pricing.

Five dollars a month gets you onto Publer, with a free tier below that. Bulk scheduling and post recycling are its strengths.

The per-account math is where most roundups slip. On Professional, Publer charges $5 for one account and $9 for two, and from the third account the whole plan bills at $4 each. Business runs $10, then $17, then $7 per account. So eight accounts on Professional is $32 a month on monthly billing, not the $40 a flat “$5 each” reading gives you. Team members cost extra on top. The cost per account moves as you add them, and our Publer comparison walks the math.

On agents, Publer has opened up. Its MCP help article, updated 15 October 2026, says the MCP server is available on Business and Enterprise, at mcp.publer.com with OAuth or an API key. The API is Business and up as well, so an agent workflow starts at $10 a month for one account. The account-by-account cost of that gate runs against Postiz in a separate comparison.

“It also has API and MCP now, which I’m very excited to integrate into our overall workflow.” (a Trustpilot reviewer)

Pros:

• Genuinely free tier to start
• Strong bulk scheduling and post recycling
• MCP server and API on the Business plan

Cons:

• Per-account pricing adds up, and seats cost extra on top
• API and MCP are not on the cheaper Professional plan

Pricing: Free tier available. Professional is $5/mo for one account, $9 for two, then $4 per account from the third. Business is $10, $17, then $7 per account. Yearly billing came to 20% less on Publer’s own calculator.

Ideal for: Solo creators with a handful of accounts who want the cheapest hosted option.

Bottom line: The cheapest hosted pick here while your account count stays small.

7. Metricool: Best for marketers who need analytics, not just publishing

Metricool pairs scheduling with the reporting depth open-source tools tend to skip.

Reporting is where a lightweight scheduler runs out of road, usually the day someone asks you to explain a month of performance in a deck. Metricool is built for that reader. It handles scheduling competently and reporting genuinely well, and its Starter tier analyzes up to 100 competitors. The free plan tracks 5.

On agents it is unusually open. Its MCP page says the server at ai.metricool.com/mcp “works with any Metricool plan, including the free account,” and the pricing page now lists the MCP on the free plan too. Your plan’s limits still apply, so the free account sees 30 days of data and 20 scheduled posts. The separate HTTP API used by Zapier and Make sits on Advanced. I put both tools’ MCP servers side by side in a head-to-head on Postiz and Metricool.

“The interface is easy to use, the calendar makes scheduling across multiple accounts pretty painless, and the analytics are solid.” (a Reddit user in r/SocialMediaManagers)

Pros:

• Reporting and competitor analysis well beyond the category norm
• Hosted MCP server on every plan, including free
• Free tier to evaluate it

Cons:

• AI creation features are secondary
• The free plan only keeps 30 days of data
• The Zapier and Make API needs the Advanced plan

Pricing: Free plan available. Starter from about $20/mo and Advanced from about $53/mo at the annual rate, $25 and $67 billed monthly.

Ideal for: Marketers who have to show results to someone else.

Bottom line: Pick it when the reporting matters as much as the posting.

8. SocialPilot: Best for small agencies managing client accounts

SocialPilot focuses on client management and approval workflows for agencies.

Agencies are SocialPilot’s core buyer, and it is a reasonable landing spot if you were self-hosting Postiz to keep client costs down. Manager approvals and a social inbox arrive on Standard, and client approvals and white-label reports on Premium.

Seats are where the price moves. Essentials is $30 a month for 7 accounts and exactly one user. Teammates mean Standard at $50, with 15 accounts and 3 users, and white-label reports start on Premium at $100. SocialPilot also runs a first-party MCP server at mcp.socialpilot.co/mcp, which answered my probe with a 401. Its REST API is a different story: the plans page lists API access on Enterprise only, so a pipeline that needs REST rather than an agent is a sales call.

“Social Pilot took my monthly Social Media scheduling from 2 weeks every month to a day and a half.” (a Trustpilot reviewer)

Pros:

• Approval workflows and a social inbox from the Standard plan
• First-party MCP server
• Low entry price for an agency-focused tool

Cons:

• The $30 Essentials tier is single-user
• White-label reports start at $100/mo
• REST API access is Enterprise only

Pricing: Essentials $30/mo (7 accounts, 1 user), Standard $50/mo (15 accounts, 3 users), Premium $100/mo (25 accounts, 6 users). Annual billing saves 15%. Extra accounts are $4/mo.

Ideal for: Small agencies who need approvals and client reporting without enterprise pricing.

Bottom line: Good value for an agency whose team works in the dashboard.

How I Chose These Postiz Alternatives

• Does it keep the API and agent story alive? Many Postiz users drive it through the API, so I flag every tool where the API or MCP sits on a higher tier.
• How far past publishing does the agent reach? Comments, DMs and analytics are where the MCP servers in this list differ most.
• Does it remove the operational load? Every pick had to reduce maintenance or make it meaningfully lighter.
• Does the pricing hold up at real account counts? Pricing that looks cheap at one profile and expensive at eight gets called out.
• Does it cover the platforms you actually use? Nobody replaces 30-plus destinations with 9 by accident, so I said plainly where coverage drops.

Pricing was read off each vendor’s own pricing page, rate card or calculator on 23 October 2026, so check the current number before you buy. Postiz’s limits and MCP tool list come from its own docs, quoted directly. Review quotes link to the thread or review they came from. The MCP column is my own reachability check, an unauthenticated JSON-RPC initialize request to each advertised endpoint, and Blotato’s tool count comes from the connected server.

How to Choose the Right Postiz Alternative

Your agent answers comments and DMs: Blotato, provided Instagram and Facebook are where your audience talks back.

The most platforms and channels from one API: Zernio, after you model the per-account bill.

A simple publishing API at one price: Post Bridge.

Self-hosting, minus the Temporal stack: Mixpost.

Cheap and hosted: Publer, or Buffer if three channels covers you.

Reports for a client or a boss: Metricool, or SocialPilot when approvals matter.

The 100-an-hour rate limit: check which Postiz you run first. Self-hosted, that number is a setting you can raise.

Thirty-plus platforms: Postiz still has the widest list, so check your networks against each tool before you move.

Sabrina’s Final Thoughts

Postiz is good software, and most people who leave it are trading a server they never wanted to babysit for a monthly bill. So the useful question is what your agent needs to do once it is connected.

If it only publishes, several tools here do that well, and Post Bridge or Buffer may be all you need. If it has to run the whole loop, from posting to answering Instagram and Facebook comments to reporting back, that is the job I built Blotato for, and you can compare the plans to see which account band fits. For the deeper head-to-head, our Blotato vs Postiz comparison runs the same numbers in more detail, and the step-by-step move off Postiz covers getting your queue across.

Postiz Alternatives FAQs

What is the best Postiz alternative?

It depends on why you are leaving. If your AI agent needs publishing plus Instagram and Facebook comments, DMs and analytics on one hosted key, Blotato is my pick, as long as its 9 platforms cover your stack. If you want to keep self-hosting with a lighter stack and a one-time license, Mixpost, and the full Mixpost and Postiz breakdown covers what that license buys you. If you just want cheap hosted scheduling, Publer.

Is Postiz actually free?

The software is free under AGPL-3.0 if you self-host it. You still pay for infrastructure, and Postiz recommends 4 vCPU and 8 GB of RAM for a small team plus PostgreSQL, Redis and Temporal. Its hosted plans start at $29 a month. The license costs nothing. The servers and the upkeep still do.

What is the best open-source Postiz alternative?

Mixpost is the main one people move to. Its free Lite edition is open source, while the paid self-hosted licenses from $299 are source-available. Both run a lighter Laravel stack than Postiz’s Temporal setup without AGPL’s network copyleft obligation. If open source is a principle for you rather than a price preference, Lite is the closest match.

Why do people leave Postiz?

For self-hosters, the cost is upkeep: a standard Postiz deployment runs PostgreSQL, Redis and Temporal alongside it, and keeping that stack healthy is your job. Stay on Postiz if it already runs smoothly on your own server and you post to networks outside the 9 Blotato supports, since Postiz covers 30-plus. If you do move, my Postiz switching checklist covers what to check first.

Is Postiz’s API really limited to 100 requests per hour?

Only on Postiz Cloud, and only for one endpoint. Postiz’s configuration reference defines API_LIMIT as the “per-hour limit on the public-API create-post endpoint,” defaulting to 90, and its API docs put Cloud at 100 while noting that one request can carry several posts. It does not tier by plan, and on a self-hosted install it is a setting you can raise.

What is the best free Postiz alternative?

Mixpost Lite, Metricool, Buffer and Zernio all have free options, and they answer different questions. Mixpost Lite is open source and keeps you self-hosting. Metricool’s free plan is hosted and includes its MCP server, with 30 days of data and 20 scheduled posts. Buffer’s free plan covers 3 channels, and Zernio’s first 2 accounts are free. If self-hosted Postiz already cost you nothing, leaving costs money, and the question is which cost you would rather pay.

Which Postiz alternatives have an MCP server?

All eight on this list. When I checked, a live MCP endpoint behind authentication answered for Blotato (mcp.blotato.com/mcp), Zernio (mcp.zernio.com/mcp), Post Bridge, Mixpost Cloud, Buffer (mcp.buffer.com/mcp), Publer (mcp.publer.com, Business and up), Metricool (ai.metricool.com/mcp) and SocialPilot (mcp.socialpilot.co/mcp), and Postiz’s own sits at mcp.postiz.com/mcp. An MCP server is table stakes now. The useful question is how much of the job it can do, which our social media MCP servers guide breaks down tool by tool.

How many MCP tools does Postiz expose?

Thirteen, by its own docs: integrationList, groupList, integrationSchema, triggerTool, schedulePostTool, postsListTool, postSettingsTool, generateImageTool, generateVideoOptions, videoFunctionTool, generateVideoTool, clippingTool and clippingStatusTool. They cover accounts, scheduling and publishing, listing posts, post settings, image and video generation, and clipping. Postiz’s docs state there is no getComments or replyToComment, so comment replies happen in the UI. Blotato’s MCP server exposes 35 tools, with the extra surface going to Instagram and Facebook comments, DMs and DM automation, plus analytics on 8 of its 9 platforms.
