There's often times I want to prevent a computer/laptop/VM from sleeping and while, yes, there's various Caffeine/Amphetamine apps they're often overkill. Instead, this small (12Kb) page does the job and only needs a web browser. It's just a very simple usage of a web api normally used for things like video players: https://developer.mozilla.org/en-US/docs/Web/API/Screen_Wake...
