What Zulip actually does
Zulip is an open-source group chat application designed for team communication. It provides a structured messaging environment to help organisations manage conversations efficiently.
Best fit: Teams that require a self-hosted alternative to proprietary group chat systems to maintain complete control over their communications data.
Worth knowing: Self-hosting group chat software often brings a significant operational burden regarding backups, user management, and system updates.
Deployment notes
As a Python application, it typically requires a separate database for data persistence and a reverse proxy to handle TLS termination.
