A locally hosted, website-based app for messaging, file transfer, and voice/video calls between devices on the same network. No internet bandwidth needed. The LAN chat app my family used stopped working one day, so I wrote my own.

| Host | Python + FastAPI server with a configuration app: start/stop, user registration, automatic local IP discovery, local TLS certificates, file-retention limits |
| Clients | Any browser on the network; no installs |
| Chat | Group chat with file transfer and status indicators |
| Calls | WebRTC voice and video over local HTTPS |
| Known issue | Local certificate generation may fail on some setups; alternatives in progress |
| Roadmap | Private messages, headless/CLI mode, PyPI distribution, dedicated clients, image previews, dark mode |
