Server Setup

The app works with any standard LibreChat server. During onboarding, you'll enter your server URL (e.g., https://chat.example.com or http://192.168.1.100:3080).

Required Configuration

Add the following to your LibreChat server's .env file:

# Safety net for native app clients.
# The app sends a browser User-Agent to pass the uaParser middleware,
# but if it ever fails to parse, this prevents ban point accumulation.
NON_BROWSER_VIOLATION_SCORE=0

Without this setting, the server's violation system may accumulate ban points against the Android client if the User-Agent check fails, eventually locking the account out.

Notes

• Registration — The app respects your server's registration settings. If registration is disabled server-side, only the login form is shown.
