I asked myself “which programming language do I actually like ?” So: the same tasks written in 32 languages. You first pick which languages do you want to enter the tournament. Then they are randomly assigned to groups, then they fall into an upper and lower brackets, then a grand final. Matchmaking gives both languages the same task, avoids repeats within a cup, and rotates through tasks you haven’t seen. The whole thing is a single HTML file (about 130 KB gzipped, all 960 snippets included) and progress saved in local storage. If you want the over-the-top version and not well-tested 3D fighting-game arena with the same tournament: https://chalmovsky.com/prog-lang-cup/ I prefer the plain version though:D. You can also switch between the two mid tournament they both use the same data from the local storage. It was written with AI, so if some code snippet isn’t idiomatic, please tell me (or send a PR, it’s MIT): https://github.com/chalmovsky/com/tree/main/prog-lang-cup I’m collecting anonymous results (which language wins each duel) and will post the overall standings in a few weeks if there is some data :D.

I really enjoyed playing with this so I hope you will too!
