+### Desktop app (beta)

+The desktop app is the same proxy and dashboard in a native window, with a tray and bundled `ocx`.
+It attaches to a proxy that is already running, or starts its bundled one, and the dashboard stays
+on the proxy port (**http://localhost:10100** unless you configured another). Pick the file for your
+platform from the [latest release](https://github.com/lidge-jun/opencodex/releases/latest):

+| Linux (x86_64) | `OpenCodex-<version>-linux-x86_64.AppImage` or `-linux-amd64.deb` | The tray needs an AppIndicator-capable desktop |
