Postiz

Postiz is an open-source social media scheduling tool for planning posts, managing accounts, and tracking performance in one place. It is built for teams and automation workflows that need scheduling, collaboration, and audience growth across social platforms.

It can schedule posts, measure work with analytics, and let team members collaborate, comment, and schedule posts. It also offers a public API, a NodeJS SDK, an N8N custom node, and a Make.com integration. The agent CLI is available for OpenClaw and other agents.

Postiz publishes to platforms including X, Bluesky, Mastodon, Discord, Instagram, YouTube, LinkedIn, TikTok, Reddit, and Threads, with the same feature set whether you self-host or use the hosted service. Users authenticate directly with each platform through official OAuth flows. It is built on NextJS and NestJS with a PostgreSQL database.
