ToolifyNav verdict
Postiz is a scheduler for people who would rather let software do the scheduling. Its MCP server and API make it unusually easy to let an AI assistant produce and queue posts while a human approves on the calendar, and the open-source edition gives technical teams an exit from SaaS pricing altogether. In return you get leaner analytics than the big suites and, if self-hosting, real maintenance responsibility. For developers, automation-minded marketers and agencies juggling many channels, it is one of the most flexible options available; teams seeking turnkey reporting and governance should look at heavier platforms.
About
About Postiz
Postiz is a social media scheduler built for a world where AI agents do part of the work. Its hosted service at postiz.com and its open-source edition on GitHub — licensed AGPL-3.0, with more than 37,000 stars — are the same product, so teams can choose between a managed cloud account and running it on their own server.
The core is familiar: connect channels, compose posts, and arrange them on a visual calendar with day, week and month views, then publish to more than 30 networks, including the major social platforms plus blogging targets such as WordPress, Medium, Hashnode and Dev.to. Features such as RSS auto-posting, posting sets, signatures and team collaboration cover routine publishing.
The distinctive part is how agents plug in. Postiz ships an MCP server and CLI, so assistants such as Claude, ChatGPT, Claude Code or Codex can draft and schedule posts on your behalf while you review everything in the calendar. A public API, OAuth2 flow and SDK let developers build their own posting products on top of Postiz, and automation users can wire it into n8n, Make or Zapier for hands-free approval and publishing pipelines. Hosted plans scale by number of channels; all include unlimited posts and the MCP and API features, and start with a seven-day trial.
