On macOS just run `caffeinate` from the terminal (or `man caffeinate` for more info on the options). I know OP copped to “various Caffeine/Amphetamine apps” but said they're often “overkill”. In this case I think a system-provided command is less overkill than a web page that either uses a browser API or plays an empty video.

Does this stay on indefinitely? I don’t like using the command line to enable settings that I only need for an hour or so. I often forget to turn them off.

I like that OP’s site turns keeps my machine awake while it’s open, and I can just close the tab when I want my machine to behave normally.

So I like this and I'm trying it out, it seemingly works OK.

However, the GREEN background is very annoying. I don't need the whole webpage to be green for me to know it's on and working. I can't minimize the browser (firefox) because then it apparently doesn't work. So I'm left with a very big green screen sitting in the corner of my eye. Wondering too the effect of that in terms of screen color burnout (if that's even a thing anymore).

I would definitely recommend to tone down the color scheme. Stay away from green. Just go with grey and darker grey or black for your on/off schemes, including inside of the slider button.

My use case is that I have the "nosleep" computer on the side of my desk. It catches IM/chat messages (from Teams, etc.) and email (from Outlook). I don't like my primary development machine bothered by these notifications, but I do like having that machine "awake" and alert to chat/email notifications (and I can't (or shouldn't) change the default policies on that machine).

My work resets my Mac sleep timer settings on reboot or update. This is very annoying for maintaining persistent connections to servers, such as my development machine. I wrote a simple Python script to move my mouse pointer by 1-5 pixels at random intervals. Works great, and it always looks like I’m online for prying eyes in Slack.

You might need `caffeinate -d` to prevent the display from sleeping.

While this does work, I agree with OP here. The man page for caffeinate says that it prevents system sleep and, as far as I can tell, it does not do that on my M1 MBP using Monterey.

I do a `caffeinate -d` and then throw my mouse to a hot corner to activate the screen saver.

I obviously missed the NoSleep.js at the end ... but then I wonder: what is then so special about this website?

It prevents your computer from sleeping with just a webpage. Why does it need to be more special than that?

I think karrussell is talking about the live demo linked from NoSleep.js' project page: https://richtr.github.io/NoSleep.js/example/

I've been using a Zoom meeting of just myself, locked, audio and camera off. Worked like a charm when I needed to discharge a swelling battery.

That's pretty handy! I remember a coworker asking me for something similar years ago and me just making something on the fly in C++ (a glorified wrapper over "SetThreadExecutionState"): https://gist.github.com/Hamcha/3a7b3e7518e13d1fba7e

I wonder if that page would even work, his work PC at the time (late 2015) was a dual-socket Pentium III which ran surprisingly OK given the already 15+ years of age, but lacked in software support as apps like Skype and Chrome at one point started shipping binaries that required.. SSE2
