Postiz, open-source Buffer and Hootsuite alternative, hits 38,617 GitHub stars: Reveneau

Why it mattersA small team paying a hosted scheduler can run the same job on its own server. The platform tokens then stay with the team.

A small agency pays a hosted scheduler like Buffer or Hootsuite month after month. The per-seat and per-channel limits often cost more than the base plan. Postiz does the same job on the user's own server. The project is on Trendshift's daily list for 27 October.

Postiz is at gitroomhq/postiz-app. GitHub's own API returns 38,617 stars and 7,464 forks on 27 October 2026. Trendshift ranks it 20th on its daily list the same day. The repository was created on 8 July 2023. The project has had three years to reach this count.

What it does

The README names 14 destinations the scheduler can post to. Those are Instagram, YouTube, Dribbble, LinkedIn, Reddit, TikTok, Facebook, Pinterest, Threads, X, Slack, Discord, Mastodon and Bluesky. Named features include a calendar view, cross-posting, repeated posts, post comments, delays, sets, signatures and RSS auto-post. The code is TypeScript on NextJS and NestJS. It uses Prisma for Postgres, Temporal for scheduling, and Resend for mail.

The licence is AGPL-3.0. The maintainer says the project does not gate features or limit the licence. The cloud version and the self-hosted one carry the same features.

What is new in the last month

The v2.25.0 release on 2 October 2026 adds inline comments on the post preview page. A reviewer selects text and anchors a thread to it. The reviewer can reply, resolve and mark resolved. A reviewer without a Postiz account can comment anonymously. An optional invisible reCAPTCHA v2 check guards those comments.

The same release adds a self-hosted MCP connector. Postiz Cloud can relay tool calls to a user's own Postiz instance. The relay uses the self-hosted instance's API key. An agent on the cloud account can then post into the self-hosted account.

Three security releases followed. v2.25.1 came on 11 October 2026. v2.25.2 came on 23 October 2026. v2.25.3 came on 24 October 2026. Each one resolved a security advisory. The maintainer asked all users to upgrade.

Why a reader cares

Postiz posts to the same list of platforms a marketer uses every day. The MCP connector and the public API let AI agents call Postiz directly. A coding agent inside Claude Code, Codex or Cursor can schedule a post the same way a human can. Named integrations with N8N, Make.com and Zapier give teams a second route for workflows.

A team moving off a hosted scheduler loses the vendor's uptime, patching and backups. The team then has to do that work itself. A one-person agency with ten channels and no server staff may prefer the paid version. A ten-person studio with a developer on staff gets a cheaper monthly bill. The platform tokens stay on its own server.
