About
Postiz is an open-source social media scheduling tool with a public API for creating posts, managing channels, and reading analytics across networks. The hosted version offers a 7-day free trial; if you want free forever, you can self-host the AGPL-licensed version on your own server. A practical pick for developers who want a Buffer-style API without the enterprise price tag.
