Free football tools for fans & developers
15 calculators, simulators, and predictors. No signup, no ads, no data leaves your browser. Built around our football data API but useful on their own.
Each tool pairs with a TheStatsAPI endpoint: the odds and betting calculators run on the Football Odds API, the prediction tools on xG and match stats, and the World Cup tools on the fixtures API. Use a tool to prototype, then wire it to live data.
