Open-source social scheduler available as cloud or self-hosted under AGPL.
Head-to-head
Postiz vs Mixpost (2026): which open-source scheduler should you use?
Self-hosted social scheduler sold as a one-time purchase, with free Lite edition.
Both are open-source social schedulers you can host yourself or rent as a cloud service. The catch: Mixpost's free Lite edition doesn't post to TikTok, YouTube or Instagram; you need Pro ($299 one-time). Postiz's open-source edition (AGPL-3.0) supports TikTok, YouTube and Instagram. For a free self-hosted setup that covers short-form, pick Postiz.
Quick verdict
- Pick Postiz if you want free self-hosting that posts Shorts, TikToks and Reels, or a cloud plan with unlimited posts and built-in YouTube clipping.
- Pick Mixpost if you prefer a one-time licence over a subscription, run a PHP/Laravel stack, or are an agency wanting white-label (Enterprise).

Self-hosting reality
Free software isn't free to run. You'll pay for a small server, and you have to register your own developer apps with TikTok, Meta and Google to post through their APIs. Postiz offers paid help getting those apps approved, and says Facebook, Instagram, Threads and YouTube take longest. Postiz also says new features arrive on its hosted version first.
Mixpost Pro's one-time $299 includes one year of updates and a perpetual fallback licence, so it keeps working after that year. For a creator posting for years, that can cost less than a cloud subscription.
Cloud plans compared
At $29/mo both cloud entry plans cost the same. Postiz Standard gives 5 channels and unlimited posts. Mixpost Spark caps you at 100 scheduled posts a month, which is about three a day across all accounts. If you post daily to TikTok, Shorts and Reels, Postiz is the roomier entry plan; Mixpost Momentum ($49/mo) lifts you to 500 posts and 24 channels.
A three-year cost example
On cloud plans: Postiz Standard billed yearly is $23 x 36 = $828 over three years. Mixpost Spark billed yearly is $249 x 3 = $747. Self-hosted, Mixpost Pro is $299 once (updates for the first year), and Postiz is free, plus server costs for either. The cheapest route that still posts to TikTok and YouTube is self-hosted Postiz.
How to choose
- Count your posts. Over 100 a month rules out Mixpost Spark.
- Decide who runs the server. If nobody wants to handle updates and API app approvals, go cloud.
- Check your platforms. Short-form on Mixpost needs Pro or cloud.
- Check the licence if you'll modify the code: AGPL-3.0 (Postiz) asks you to share changes when you offer it as a service.
Which should you pick?
- Solo creator, free, short-form: self-hosted Postiz.
- Prefer to buy once: Mixpost Pro at $299.
- Agency reselling a scheduler: Mixpost Enterprise.
- Don't want to run a server: either cloud plan; Postiz for unlimited posts.
Other options: free social media schedulers.
