Chiù
I'm building a small tray/menu-bar app called Chiù that automatically prevents your computer from going to sleep while there's a detectable network activity, usually a download, e.g. a Steam game download/update. I made it because I was tired of going into the system settings to disable automatic sleep manually whenever I wanted to leave a large download running. It's intentionally quite simple, but you can configure things like the activity threshold and grace period. There's also a manual keep-awake mode. It runs on Windows and macOS. I don't currently have Apple/Microsoft publisher certificates because I'd first like to see whether anyone actually finds it useful before paying for those, so the OS may show a warning on first launch. https://github.com/Ma1kovich/chiu
