Postiz

YES

Replaceable in one session with an AI coding agent.

An open-source social media scheduler covering a dozen platforms, with a calendar, a team workflow and a self-hosted option.

Promptfree, for everyone, and the only version there is

Self-host it. The credentials are the work.

WHAT SELF-HOSTING ACTUALLY INVOLVES
- Docker Compose gets the app running in an hour
- Registering your own application on each platform and getting publishing approved takes days
- Budget for the second part; it is the whole cost

RUNNING IT
- Compose with Postgres and Redis, a reverse proxy with TLS
- Callback URLs must match exactly what each platform has registered

TOKENS
- Stored encrypted; check the refresh works before a token expires rather than after
- A clear reconnect prompt when a platform revokes access, which they do

BACKUPS
- Postgres nightly, off the machine, restored once as a test

Include the compose file, the callback list and the backup script.

What you lose

A dozen platform integrations somebody keeps working as each one changes
Registered applications with publishing permission already approved
A hosted instance with upgrades
