FDB4 is a free football results database and statistics platform built for supporters, researchers, and anyone curious about match patterns. It indexes more than half a million results across club and national football, with coverage of tournaments, teams, players, referees, and historical matchups. Its flagship feature finds teams with the longest active runs of consecutive matches without a draw, while draw statistics, current streaks, records, and a draw predictor help users explore how often matches end level.

Visitors can browse results and fixtures by date, country, tournament, or team, review league tables, compare head-to-head histories, and examine Elo ratings and charts. FDB4 also offers tools including a pitch editor, margin calculator, accumulator tax and Kelly stake calculators, alongside educational material about odds, outcomes, and betting systems. A football-themed 1v1 browser game is available to play online or offline, with a leaderboard.

Developers can access the data through a REST API, an MCP server for AI agents, and embeddable widgets. FDB4 states that its statistics and tools are not betting advice
