By default, all installed apps start automatically when umbrelOS boots. You can control this by stopping apps you don't want running.

Right-click the app icon on your home screen and select Stop or Restart. When an app is stopped, its icon will indicate that it's not running.
Click a stopped app's icon on your home screen to start it again.
There's no separate auto-start setting — simply stop the app. Stopped apps stay stopped even when you reboot your Umbrel. This makes it easy to keep apps installed without having them use resources in the background. When you're ready to use the app again, just click it to start it.
