Postiz
Open-source AI social scheduler for 30+ networks, with cloud or free self-hosting.
About
Postiz is an open-source, agentic social media scheduling platform that plans and publishes to 30 or more networks, from X and Instagram to Reddit, Mastodon, Lemmy, and Nostr, through one visual calendar. Its AI copilot writes captions and generates images in any language, and AI agents such as Claude or ChatGPT can drive the whole workflow through a hosted MCP server, a CLI, and a public API that ships on every plan.
The cloud version starts at $29 a month for Standard (5 channels, 400 posts) and scales to $99 Ultimate for 100 channels, with a 7-day trial. The same code is AGPL-3.0 on GitHub and can be self-hosted with Docker at no license cost, which made it one of the fastest-growing self-hosted tools of the past year with tens of thousands of stars.

Trust score — 8/10
Scored 9/10 (TIER verified, metrics-v1). Evidence: Postiz is AGPL-3.0 on GitHub (gitroomhq/postiz-app, 37,266 stars as of Oct 2026), verified via the GitHub API; multiple independent 2026 guides confirm self-hosting via Docker, cloud pricing ($29-$99/mo), 30+ network support, and MCP/CLI agent tooling. Strengths: fully open source, strong community traction, public codebase inspectable, Docker self-host. Docked for: (1) self-hosting requires handling per-network developer-app approvals yourself; (2) analytics depth trails dedicated analytics tools. License: AGPL-3.0.
