Mixpost vs Postiz: Better Option for Social Media Posting?
Mixpost vs Postiz: one free tier is the whole product, the other is three platforms. Plus MIT vs AGPL and the real three-year cost of self-hosting.
Mixpost vs Postiz looks like a coin flip until you find out what each one means by “free.” Postiz self-hosted hands you the entire product: every platform, the API, MCP, AI generation, nothing held back. Mixpost’s free Lite edition hands you three destinations, Facebook Pages, X and Mastodon, and puts Instagram behind a $299 license.
That is the fact that decides this for most people, and it is buried on both websites.
If you have already decided Mixpost is not the one and want the wider field, we compared the best Mixpost alternatives separately. The other decider here is a line of legal text. Mixpost’s free edition ships under MIT, Postiz under AGPL-3.0. If you intend to build anything commercial on top, that clause outranks every feature row below.
I run a hosted tool in this category, disclosed properly further down. The first two thirds of this is about choosing between these two, including the parts where hosted tools like mine are the wrong answer.
Mixpost vs Postiz: At a Glance
Reach for Mixpost when the AGPL scares your lawyer, when you would rather pay $299 once than $29 every month, or when your team writes Laravel and wants source they can actually modify.
Reach for Postiz when you want every feature free on your own hardware, when your audience sits on Discord, Telegram or Mastodon, or when you want a hosted escape hatch if maintenance stops being fun.
Both answers assume a server you maintain. If that assumption is the thing you are actually questioning, see what a managed plan covers, and I will be specific later about when it is the wrong call.
Are Mixpost and Postiz Even the Same Category?
Closer than most pairs, but they are built by different kinds of teams for different kinds of buyers.
Postiz is a TypeScript and Node application with an agentic bent. The marketing leads with AI copilots, a smart agent, and a CLI. It self-hosts under AGPL-3.0 through Docker, and there is a hosted cloud plan if you decide the servers are not worth it. The project has passed 34,000 GitHub stars since mid-2023.
Mixpost is a Laravel package built by Inovector, and it self-hosts only. There is no Mixpost cloud, and that is deliberate. The pitch is data ownership: your posts, tokens and media never leave hardware you control. It sits around 3,500 stars with a repo dating to 2022.
The structural difference is how each one splits free from paid. Postiz splits by hosting: run it yourself and you get everything, or pay to have it run for you. Mixpost splits by edition: Lite is free and deliberately limited, Pro is $299 and unlocks the product. Same “open source” label, different meaning.
Who Mixpost Is Built For
Mixpost is built for agencies, privacy-sensitive businesses, and Laravel developers. The pricing is a one-time purchase rather than a subscription, which is unusual enough in this category to be the main reason people pick it.
Three editions on the pricing page. Lite is free and MIT-licensed. Pro is $299 one-time and adds every platform, the API, MCP, the AI assistant, approval flows, white labeling and multi-tenant workspaces. Enterprise is $1,199 and adds subscription management and billing so you can run a SaaS on top of it, which a Pro license explicitly does not permit.
Two details deserve emphasis because they are easy to misread.
First, “one-time payment” comes with an asterisk. You get a perpetual fallback license, so the software keeps working forever, but updates are included for one year. After that, renewal is optional and paid. Calling it “lifetime” without that qualifier oversells it.
Second, the free Lite edition supports exactly three destinations: Facebook Pages, X, and Mastodon. Instagram, LinkedIn, TikTok, YouTube, Pinterest, Threads, Bluesky and Google Business Profile are all Pro-only. If you came for a free self-hosted tool that posts to Instagram, Lite will not do it.
Mixpost’s own pages disagree slightly on the Pro total. Its FAQ enumerates eleven and omits Pixelfed, while the Pro plan card and the homepage both list Pixelfed, which would make twelve. Either way the Lite-to-Pro jump from three is the number that matters.
The API and the MCP server are also Pro features. Mixpost does ship a genuine built-in MCP server over streamable HTTP, covering workspaces, accounts, posts, tags and media, and it is not a community wrapper. But you reach it at your own domain, after you have stood up the server and bought the license.
Who Postiz Is Built For
Postiz is built for people who want maximum capability at minimum cost and are willing to run infrastructure to get it. Self-hosted, under AGPL-3.0, you get every feature: all platforms, the API, webhooks, MCP, the AI copilot, analytics. Nothing is edition-gated.
If you would rather not run it, the cloud plans are $29 a month for 5 channels, $39 for 10, $49 for 30 and $99 for 100, with a 7-day trial. That optionality is something Mixpost does not offer at all.
Platform reach is where Postiz separates. Its provider docs list 21 platforms with a connect flow plus 10 more reachable through the API, so the “30+” figure holds. Be aware what is inside it: WordPress, Medium, Dev.to and Hashnode are blogs, Listmonk is newsletters, and Skool and Whop are communities. As conventional social networks the count is lower. Still, Mastodon, Bluesky, Discord, Telegram, Slack, Reddit, Farcaster and Nostr are all reachable, which is a wider net than Mixpost casts.
The AGPL license is the trade. AGPL-3.0 has a network clause: if you modify Postiz and offer it as a service over a network, you owe your users the modified source. For personal or internal use that is irrelevant. If you planned to fork it into a white-labeled product for clients, read the license before you write code. This is precisely where Mixpost’s MIT Lite edition and its Enterprise license are aimed.
On requirements, Postiz asks for more moving parts. Postgres, Redis, and since v2.12.0, Temporal. Official system requirements list 2 vCPU and 2 GB RAM as the supported floor for the all-in-one Docker install, 4 GB or more once you add users, and 4 vCPU with 8 GB as the recommended spec. The out-of-memory warning people quote applies to building from source, not the official image, and has a documented fix.
Mixpost’s server requirements are PHP 8.3, MySQL, Redis, Supervisor, cron, FFmpeg and libvips. Fewer exotic services, but Mixpost publishes no CPU or RAM minimum at all.
Mixpost vs Postiz: Side by Side
| Category | Mixpost | Postiz |
|---|---|---|
| License (free edition) | MIT | AGPL-3.0 |
| Paid model | $299 one-time (Pro) | $29 to $99/mo (cloud) |
| Free edition scope | 3 platforms only | Full product, self-hosted |
| Hosted option | None, self-host only | Yes |
| Platforms | 11 to 12 on Pro, 3 on Lite | 21 with connect UI, 31 including API-only |
| GitHub stars | ~3,500 | ~34,200 |
| Stack | PHP 8.3, Laravel, MySQL, Redis | Node, Postgres, Redis, Temporal |
| REST API | Pro and Enterprise | All tiers |
| MCP server | Yes, built-in (Pro) | Yes, 9 tools |
| AI text | Yes, bring your own key (Pro) | Yes, included |
| AI images | Yes, bring your own key (Pro) | Yes, metered |
| AI video | No | Yes, metered |
| White label | Yes (Pro and Enterprise) | No |
| Multi-tenant workspaces | Yes (Pro and Enterprise) | Restricted by AGPL |
| Billing clients for it (SaaS) | Enterprise only | Restricted by AGPL |
| n8n | Vendor node, v0.1.1 (a year old) | Official node, actively updated |
The license row and the free-edition row are the two that actually decide it. Everything else is preference.
Where Mixpost Wins
MIT licensing on Lite. No copyleft, no network clause. If you are building something commercial on top of the free edition, this is a materially different legal position than AGPL.
One payment, not a subscription. $299 once against $29 a month means Postiz cloud passes it in ten months. If you plan to run this for years, the math favors Mixpost.
Built for reselling. White labeling, multi-tenant support, and an Enterprise tier with subscription management and billing. Postiz’s AGPL license points the other way.
A broader MCP surface. Mixpost’s tool list spans workspaces, accounts, posts, tags and media, against Postiz’s 9 tools. If your agent does more than schedule, that matters.
A stack many teams already run. Laravel, MySQL, Redis. No Temporal to learn. For a PHP shop this is a codebase your developers can actually modify.
Where Postiz Wins
The free version is the whole product. Self-host and you get every platform, the API, MCP and AI with nothing gated. Mixpost’s free tier gives you three destinations. For most people this alone settles it.
Far more reach. 21 connectable platforms against roughly a dozen, including Discord, Telegram, Slack, Reddit, Farcaster and Nostr, plus blog targets Mixpost does not touch.
A much larger community. Roughly ten times the GitHub stars, an active Discord, and more third-party material. When something breaks at 11pm, someone has probably hit it already.
An exit from self-hosting. If maintenance stops being worth it, move to cloud and keep your tool. Mixpost has no such path.
Better-maintained automation nodes. n8n-nodes-postiz is current and Postiz has a listed Make app. Inovector does publish its own n8n-nodes-mixpost, so this is not vendor-versus-community, but it sits at v0.1.1 and has not been republished in about a year, so automation there leans on the REST API and webhooks instead.
Video generation. Postiz generates video, metered by tier. Mixpost generates text and images through your own API key, but no video.
The Real Cost Math
The sticker prices mislead in both directions, so here is the three-year view. Self-hosting either one means a server, so assume a modest $12 a month VPS in both self-host columns.
| Scenario | Year 1 | Year 3 total |
|---|---|---|
| Mixpost Lite (3 platforms) | $144 | $432 |
| Mixpost Pro, self-hosted | $443 | $731 |
| Postiz self-hosted | $144 | $432 |
| Postiz cloud, 10 channels | $468 | $1,404 |
Postiz self-hosted is the cheapest way to get a full-featured tool, full stop. Mixpost Pro costs $299 more than Postiz self-hosted for a narrower platform list, and you are buying the license, the MIT-adjacent commercial freedom on Lite, and the white-label rights, not extra reach.
The column none of this shows is your time. Both require you to patch a server, rotate OAuth tokens when a platform expires them, and fix the queue when a worker dies. That is the invoice that does not appear on a pricing page, and it is the same invoice for both.
Three honest caveats. If you only need Facebook, X and Mastodon, Mixpost Lite is free forever and Postiz self-hosted is overkill. If you are reselling to clients, Mixpost’s Enterprise license is designed for that and AGPL fights you. And if you are a Laravel team, the value of a codebase you can read yourself is real even though it never shows up in a table.
The Third Option: Paying Someone Else to Run It
Disclosure: I built Blotato, so read this as an interested party and weigh the two sections above more heavily.
Blotato is the hosted answer to the question both tools above answer by giving you a server. It is $29 a month flat for 20 accounts, publishes to 9 platforms, and exposes a hosted MCP server at mcp.blotato.com/mcp covering publishing, scheduling, comments, messaging and analytics behind one key. There is nothing to install and no queue worker to babysit at 2am.
Where it genuinely does not compete: you cannot self-host it, and you cannot read the source. If data residency is a compliance requirement, or if owning the code is the point, neither Blotato nor any hosted tool clears that bar and you should stop reading here and go install Mixpost or Postiz.
Also, both tools above reach more destinations than our 9, and our analytics covers 5 platforms while comments and DMs cover Instagram and Facebook. And one thing to flag for anyone here for the API: our 7-day trial excludes API access, and generating a key ends the trial and starts the Starter subscription, so plan on subscribing rather than trialing. The current plans list what is included.
Use Mixpost If
- You need MIT licensing rather than AGPL copyleft.
- You want to pay once instead of monthly.
- You are white labeling or reselling to clients.
- Your team writes Laravel and wants to modify the code.
- Facebook, X and Mastodon are enough to start free.
Use Postiz If
- You want the complete product free while self-hosting.
- You need Discord, Telegram, Slack, Reddit, Farcaster or Nostr.
- You want the option to move to a hosted plan later.
- You want a larger community when something breaks.
- You need AI video generation in the same tool.
Sabrina’s Final Take
For most people asking this question, if you are willing to run Postgres, Redis and Temporal yourself, Postiz self-hosted is the stronger default. A free tool that does everything beats a free tool that does three platforms, and the community around it is ten times larger. That conclusion holds only as long as you are the one maintaining the server, which is the condition doing most of the work in that sentence.
Mixpost earns the $299 in specific cases, and they are real ones. If AGPL blocks what you are building, if you are white labeling for clients, or if your team lives in Laravel, that license is worth paying for and the one-time price ages well.
My honest advice: install Postiz self-hosted first, since it costs a VPS and an evening to find out. If the license blocks you or you need to resell it, buy Mixpost Pro without hesitation. And if you get three months in and realize the maintenance is the actual product you bought, that is when handing the servers to someone else becomes worth pricing. If self-hosting turns out not to be the requirement you thought it was, Postiz against a hosted API like Zernio is the next comparison to read.

Mixpost vs Postiz FAQs
Is Mixpost or Postiz cheaper?
Postiz, in most cases. Self-hosted Postiz is free and complete, while Mixpost’s free Lite edition covers only Facebook Pages, X and Mastodon. Mixpost Pro costs $299 one-time to unlock the rest. Postiz only costs money if you choose cloud hosting, which starts at $29 a month and passes Mixpost’s one-time price in about ten months.
What is the license difference between Mixpost and Postiz?
Mixpost Lite is MIT, which is permissive with no copyleft obligation. Postiz is AGPL-3.0, which includes a network clause: modify it and offer it as a service and you must share your modified source. For internal use the difference is academic. For building a commercial product on top, it is decisive, and it is why Mixpost sells an Enterprise license for SaaS.
Do Mixpost and Postiz both have MCP servers?
Yes, both ship official built-in MCP servers, so this is no longer a differentiator. Mixpost serves its over streamable HTTP but gates MCP behind the $299 Pro license and your own server. Postiz exposes 9 tools and includes MCP in the free self-hosted edition. Blotato, Zernio and Ayrshare all ship one too, as covered in the best social media MCP servers.
Can you self-host Mixpost for free?
Yes, the Lite edition is free and MIT-licensed, but it publishes only to Facebook Pages, X and Mastodon. Instagram, LinkedIn, TikTok, YouTube, Pinterest, Threads, Bluesky, Google Business Profile and Pixelfed require the $299 Pro license, as do the API, MCP and AI assistant.
Which supports more social platforms?
Postiz, by a wide margin. Its docs list 21 platforms with an in-app connect flow plus 10 more available through the API only. Mixpost supports eleven or twelve on Pro depending which of its own pages you read, and 3 on free Lite. Note that several Postiz targets are blogs, newsletters or communities rather than social networks, so the like-for-like gap is narrower than the raw totals suggest.
What does self-hosting either one actually require?
Mixpost needs PHP 8.3, MySQL, Redis, Supervisor, cron, FFmpeg and libvips, and publishes no CPU or RAM minimum. Postiz needs Postgres, Redis and Temporal, with official requirements listing 2 vCPU and 2 GB RAM as the supported floor, 4 GB or more for multiple users, and 8 GB as the recommended spec. Both leave you responsible for updates, OAuth token renewals and uptime.
