The backstory
Postiz is an open-source, AI-native social media scheduler you can self-host, covering posting, analytics, and generation across platforms. ChatGPT drafts captions and native platform schedulers cover posting, but Postiz treats generation as one feature inside an ownable, extensible tool rather than its whole reason to exist. It survived because being open-source and self-hostable gives it control, privacy, and a cost profile that a bundled feature can't undercut.
