marccer is a static, backend-free league-race dashboard — Elo-style team ratings, Poisson/Dixon-Coles match prediction, and Monte Carlo season simulation, all computed client-side from your own league's data. No server, no database required.

This isn't a ready-to-run app you install — it's a source template you fork and configure with your own league's teams and results, then deploy as a static site. See the README for the full self-hosting walkthrough.

Fork the repo, or grab a source snapshot directly:

npm install → npm run dev to run the demo league locally.

To set up your own league: write data/teams.json and data/league.json, then run npm run init-schedule to generate the full-season fixture list. Full details in the README.

marccer is free and MIT-licensed. If it's useful to you, a coffee is always appreciated — no obligation.
