Chess Caddy handles registration, Swiss pairings, results, and live standings — all from one laptop, even with no internet. You run the room; it does the math.
No sign-up. Works offline. Your data stays in your browser.
Everything you need
No spreadsheets, no pairing cards, no second-guessing the math. Just the four things that actually make a club tournament work.
One click pairs each round by score — no rematches, balanced colors, and fair byes handled for you.
Run the whole event with no internet. Everything saves to your browser, so a dropped connection never stops play.
Enter a result and the leaderboard updates instantly — with Buchholz tiebreaks and medals for the top three.
Post pairings on the wall or hand out standings. Export the whole tournament as a file to back up or reopen later.
Add players in seconds, edit on the fly, and withdraw or re-enter anyone without breaking the standings.
Open it in any browser and start. No account, no setup, no cost — and your player data never leaves your device.
How it works
If you can run a club night, you can run Chess Caddy.
Name the tournament, pick the number of rounds, and type in your players with optional ratings.
Tap to generate pairings and board assignments, then click each result as games finish.
The leaderboard updates live with tiebreaks. Repeat each round, then crown your champion.
It's free, it's instant, and there's nothing to download.
