About Postiz
Postiz is an open source social media scheduler that works with AI agents, a public API and a visual calendar. It is built for teams that want to plan posts across many channels from one place.
What it does
You can schedule posts to more than 30 networks from a single calendar and review what the AI agents have drafted before it goes live. Agents such as ChatGPT or Claude can use the CLI and MCP server to create and schedule posts. Developers can build their own posting features with OAuth2, an SDK and the public API. Automation tools such as n8n and Make.com can also draft, approve and publish posts.
Key features
- Schedule posts to 30+ channels from one calendar
- AI agents draft and schedule posts
- Public API and OAuth2 for developers
- CLI and MCP server access
- Connects to n8n and Make.com
Who it's for
Postiz suits marketers who want AI help with posting, developers who build publishing features and automation teams. It is less suited to users who only want a simple scheduler without integrations.
Pricing and good to know
Postiz is open source under the AGPL-3.0 licence, so you can run it on your own servers. The hosted service lists a start price of $0 with a 7-day trial. Self-hosting means you handle updates and channel setup yourself, and AI agent output should be reviewed before posts are published.
