Chatstead

什麼是 Chatstead？

Chatstead is a real-time team chat you run entirely on your own server — no Firebase, no Agora, no third-party services. Messaging, group chats, files, voice messages, WebRTC calls, reactions, search, push notifications and a white-label admin panel. One command installs it on a small Ubuntu VPS; add a domain and it gets a free Let's Encrypt certificate automatically. Docker too. Storage is the SQLite engine built into Node.js — no separate database. One-time licence, no subscription.
