What it is
A self-hosted social scheduler — the open-source answer to Buffer. One calendar publishes to X, LinkedIn, Reddit, YouTube, TikTok, Instagram, Threads, Bluesky, Mastodon and more, with AI assistance for drafting the posts.
What it is good for. Consistency, not cleverness, is what builds an audience — and manual cross-posting is precisely where solo founders quietly stop. For a B2B tool, LinkedIn and X are where buyers actually are, and queueing a month of posts in one sitting is worth more than any individual growth tactic. Self-hosting also means adding a platform never adds a subscription.
- Widest platform coverage of any open-source scheduler
- Very actively developed, with a real company behind it
- Built-in AI drafting fits an AI-assisted workflow
- Heavy stack — Next.js, NestJS, Postgres, Redis, workers. Check the server's RAM first
- Getting API approval from each platform (especially X and TikTok) is the real work, and it's tedious
- AGPL brings obligations if you ever expose a modified instance
