Toolglade’s take

Postiz stands out in a crowded scheduling market by being genuinely open source and self-hostable with full feature parity, which is rare and valuable. Its API and MCP server make it a developer favorite and a real Buffer alternative you can own. The cloud plan at $29/month is fair, and self-hosting is free if you can run it. Non-technical users may find self-hosting a hurdle and should just use the cloud version.

About Postiz

Postiz is an open-source, self-hostable AI social media scheduler for 30+ networks, with a public API, MCP server, and a visual calendar, offered free self-hosted or from $29/month in the cloud.

Postiz is a fast-growing open-source social media scheduler created by indie hacker Nevo David that supports over 30 networks including Bluesky, Threads, Mastodon, Reddit, and Warpcast alongside the mainstream platforms. It combines a visual content calendar with AI features for generating posts and media, and it distinguishes itself with a real public API, an MCP server, and integrations with automation tools like n8n and Make. Being AGPL-3.0 licensed, it can be self-hosted at no software cost. The project has attracted a large developer community, with tens of thousands of GitHub stars and an active release cadence. A managed cloud version starts at $29/month for those who prefer not to self-host, and crucially the self-hosted build ships at full feature parity with no gating. This makes Postiz a rare pick for privacy-conscious teams, agencies, and developers who want to own their social stack and even drive it from AI assistants like Claude or ChatGPT.
