How to stop auto restart?

Hello. I want to stop this ‘auto restarting’ thing after editing a file.
I want to restart it only if I save, how can I do this?

Sure, you can use a watch.json file. See https://glitch.com/help/restart/. Note that there’s no ‘save’ option in Glitch, though. But you can make it so it only triggers a restart after changing a specific file for example.
