skillrank.games
Website to track match results, get ratings for players, and perform matchmaking for your games. Inspired by elovation and built on Cloudflare Workers. Here's an example leaderboard to check out. I mostly made this website for myself meaning the frontend isn't very polished and a little brittle. Feel free to leave issues and PR's for any problems or features you'd like to see addressed.
This uses trueskill to handle ratings but with some tweaking can easily use any rating system supported in the skillratings crate.
