# Suite Desktop runtime flags

Runtime flags can be used when running the Suite Desktop executable, enabling or disabling certain features. For example: `./Trezor-Suite-22.7.2.AppImage --open-devtools` will run with this flag turned on, which will result in opening DevTools on app launch.
The table below lists only the custom flags defined by Suite. For a full list, see also flags exposed by
[Electron](https://www.electronjs.org/docs/latest/api/command-line-switches) and [Chromium](https://peter.sh/experiments/chromium-command-line-switches/)
