Key takeaways
- Self-hosted Postiz is free under AGPL-3.0. You still need a server, your own platform apps and your own AI keys.
- Mixpost is the other open source choice. Lite is free under MIT, but it publishes only to Facebook Pages, X and Mastodon.
- Postiz has no enforced approval: anyone with the preview link can comment, and nothing blocks publishing. Flekh blocks it until approval.
How we chose: tools that do the same job as Postiz. We checked each price on the vendor's own page on Oct 28, 2026. Flekh is our product, and we list its weak points too.

Questions
- Is there another open source social media scheduler like Postiz?
- Yes, Mixpost. Mixpost Lite is free under the MIT license, but it publishes only to Facebook Pages, X and Mastodon. Mixpost Pro costs $299 once and adds Instagram, LinkedIn, TikTok, YouTube and more. Pro code is source-available, not open source, and its updates last 1 year.
- Is Postiz free if I self-host it?
- Yes, the self-hosted Postiz license is free under AGPL-3.0, with no feature gates. You still pay for the server: the official minimum is 2 vCPU and 2 GB RAM. You must create your own Meta, YouTube and TikTok apps, and AI features need your own API keys.
- Postiz vs Mixpost: which should I self-host?
- Pick Postiz for more channels and a free full feature set. Pick Mixpost for a one-time license and a PHP and MySQL stack. Postiz needs Postgres, Redis and Temporal. Mixpost needs PHP 8.3, MySQL and Redis. Mixpost Lite covers only 3 networks, so most teams need Pro at $299.
- What are the main Postiz competitors?
- Mixpost is the closest open source competitor. Hosted competitors include Buffer, Publer and Metricool, which all have free plans. Flekh competes only for teams that need client approval of video before posting. You cannot self-host any of the hosted tools on this page.
- Does Postiz have a client approval workflow?
- Partly. Postiz uses preview links: you send a link to one post, and the client comments without an account. There is no approved status, so nothing blocks publishing, and the link has no password. Flekh, Mixpost Pro and Publer Business have approval steps.
