Desk Champ

I kept running the office pool tournament on a whiteboard, and it kept ending in an argument about who had actually won. Desk Champ is the fix: pick a game, pick a format, add names, and it handles seeding, byes, fixtures and standings.

The parts I care about are the boring ones. Players submit their own results so the organiser isn't chasing anyone. Deadline emails go out automatically. There's a presentation mode that puts the bracket on the office TV with a QR code. And player records carry across competitions, so the office has a running leaderboard rather than a series of forgotten brackets.

Seventeen games supported, free, no paid tier, and you can share a competition read-only with anyone without them signing up.
