Postwire
Postwire is a social media auto poster tool that takes one content package from your AI agent and publishes a version fitted to each platform's rules.
For indie developers running several products with an AI agent. Your agent posts one package a day; Postwire derives each platform's post, publishes through official APIs, and lets a Chrome extension on your Mac fill the rest. You stop copying, trimming and clicking publish on every site.
Postwire distributes what your agent writes; it does not write content and makes no promise of reach, engagement or follower growth. X is posted through the official API only. Xiaohongshu (RED) is never auto-published: the extension fills the note and a human always clicks publish. Instagram, Facebook and Threads need your own Meta app, with your accounts added as Testers while the app is unreviewed. Platforms without an API are filled by the Chrome extension, which only works while your Mac is awake and the ops Chrome profile is open.
Postiz
Postiz is an open-source social media scheduling tool that you can self-host with Docker or use as a hosted service, with integrations for many networks.
Open source and self-hostable, so you can read the code and keep data on your own server.
A broad list of integrations, a visual calendar and team features.
Offers a public API, so it can be driven from scripts and automation tools.
Self-hosting means running and updating the server, database and workers yourself.
Like other schedulers it posts through platform integrations, so platforms without one are outside its scope.
Self-hosting Postiz is free under its open-source license; the hosted version has paid plans. See postiz.com for current pricing.
