# Self-hosted Overlay Server

> Point Overlay Desktop at your own Overlay Server.

Set the server origin before launch:

```bash theme={null}
APP_SERVER_URL=https://your-overlay-server.example.com
```

Rules:

* Use **HTTPS** in production.
* `http://localhost:3000` is acceptable for local development only.
* The server must implement Overlay discovery and `/api/v1` contracts compatible
  with this desktop version.
* Never place owner-funded provider keys or signing secrets in the desktop app
  environment.

Self-hosting the **server** is separate from installing the desktop client.
Docker/Compose applies to Overlay Server — not to the Electron GUI.
