I wrote a tiny version of this in Covid lockdowns because I felt playing trivia with friends was a bit boring, and we should all have buzzers like on game shows. I've been using it as a test project for trying out frameworks for years but I finally polished it up into a proper product. I'd love it if people try it out and give me some feedback, at the moment it sends you an emailed validation code which might put some people off trying it, if it does put you off then please let me know, I was also toying with just having free time-limited games.
