Remote Access

The Web UI can be exposed beyond your LAN using Cloudflare Tunnels or accessed directly by other devices on the same network.

LAN Access

By default the server binds to 0.0.0.0, making it accessible to any device on your local network at http://<your-ip>:3000. The mode indicator in the System tab reads LAN Only.

Cloudflare Tunnel

Saturn can start a Cloudflare Tunnel to expose the Web UI over the internet with a public HTTPS URL.

Note

cloudflared must be installed and available in your PATH. Install it from Cloudflare's releases.

Starting a Tunnel

Open the Remote subtab under System and click Start Tunnel. An access warning overlay appears first — you must confirm before the tunnel activates.

Once running, the panel shows:

  • Status — Tunnel Active with a green indicator
  • URL — the public https://*.trycloudflare.com URL
  • QR code — scannable link for mobile devices

Stopping a Tunnel

Click Stop Tunnel. The mode indicator returns to LAN Only and the public URL is immediately invalidated.

LAN Fallback

If the tunnel process crashes or cloudflared is not found, the UI falls back to LAN-only mode and displays an error in the Remote panel. All local access continues to work normally.

Warning

Enabling a tunnel exposes your Saturn instance to the public internet. Anyone with the URL can access the chat interface. Use this for temporary sharing, not permanent deployment.
