Open-source social media schedulers you can self-host
Four open-source schedulers you can run yourself: Postiz, TryPost, Mixpost Lite and SkyScheduler. Licences, networks, what self-hosting takes, hosted prices.
Four open-source social media schedulers stand out: Postiz and TryPost (AGPL-3.0, most major networks), Mixpost Lite (MIT, Facebook Pages, X and Mastodon) and SkyScheduler (Bluesky only). The software is free to run on your own server, but you'll usually need your own developer app approval from each network you post to.
What this means for you
Open source means you can download the scheduler and run it on a server you control, without a monthly fee. The trade-off is work: you set it up, keep it updated, and ask networks like Meta, LinkedIn and X to approve your own app before you can post. If that sounds like too much, each tool below also sells a hosted version.
The details
| Tool | Licence | Networks it lists | Hosted version |
|---|---|---|---|
| Postiz | AGPL-3.0 | 11, from X and LinkedIn to Pinterest, Google Business Profile and Mastodon | From $23 a month billed yearly, 5 channels |
| TryPost | AGPL-3.0 | 11, including Bluesky, Mastodon and Google Business Profile | $19 a month for unlimited accounts |
| Mixpost Lite | MIT | Facebook Pages, X, Mastodon | Cloud plans from $20.75 a month billed yearly |
| SkyScheduler | Open source (licence not checked) | Bluesky | Free hosted site |
Postiz
Postiz's code is open source under AGPL-3.0 on GitHub. The hosted plans start at $29 a month, or $23 billed yearly, for 5 channels, with an API, MCP and webhooks on every plan. Postiz itself calls self-hosting a secondary option where agent features arrive later, and notes that self-hosting needs your own developer app approvals for networks such as Instagram and Facebook.
TryPost
TryPost is AGPL-3.0, and its GitHub README says the self-hosted version has every feature with no paid tiers. The hosted plan is $19 a month for one workspace with unlimited social accounts and team members. Its docs list per-network limits, for example a 3,000-character limit on LinkedIn, and note that LinkedIn Company Pages need Marketing Developer Platform access when you self-host.
Mixpost Lite
Mixpost's free Lite edition is MIT licensed and covers Facebook Pages, X and Mastodon. For the other networks, Mixpost sells a self-hosted Pro licence for a one-time $299 (one domain, one year of updates, unlimited accounts and users) and hosted Cloud plans from $20.75 a month billed yearly. Self-hosted users register their own developer apps.
SkyScheduler
SkyScheduler is a free, open-source scheduler for Bluesky only. It schedules posts and threads of up to 10 child posts, reposts on a timer, handles several accounts, and can be self-hosted on Cloudflare Workers. The hosted site is free, with a tip page.
What self-hosting really involves
- A server: you pay for hosting, keep it running and apply updates.
- Your own app approvals: to post to Meta, LinkedIn or X from your own install, you register a developer app with each and pass its review. Our API changelog tracks those platforms' rules.
- No vendor support: the free editions rely on community support.
If you'd rather not host it
The hosted versions above remove the server work. Among hosted schedulers, PlanPost costs $16.58 a month billed yearly for 15 accounts and 1,000 posts, with an API; it isn't open source, has no free plan, and its 7-day trial needs a card. For free hosted options, see our verified free social media schedulers.
What to do next
- Business owners: Unless someone on your team runs servers, start with a hosted free plan instead of self-hosting.
- Marketers and agencies: If per-seat fees are the problem, compare TryPost's hosted plan, with unlimited team members, against your current bill.
- Developers: Pick Postiz or TryPost for wide network coverage, and register your Meta, LinkedIn and X developer apps before you deploy.
