Postiz is an agentic social media scheduling platform that lets AI agents like Claude, ChatGPT, and Grok plan, generate, and publish posts across 30+ social networks. Users can review and manage all scheduled content in a single visual calendar, with support for cross-posting, auto-repeating evergreen content, and automated engagement triggers. Postiz integrates with automation tools like n8n, Make.com, and Zapier, and exposes a public API, CLI, and MCP server for developers and agent-based workflows. It also includes a built-in AI image editor, team collaboration features, and per-channel analytics. Postiz is available as both a hosted cloud service and a self-hosted open-source deployment.
