The Swiss system, handled for you

ChessHost runs every part of a Swiss-system event so the pairings are never your problem.

Automatic Swiss Pairings

Players meet opponents on the same score and never play twice. Each new round is paired the moment results are entered.

Byes Handled

With an odd number of players, the bye is assigned automatically and fairly each round, with no tracking by you.

Tiebreaks & Standings

Scores, tiebreaks, and rankings recalculate after every round, so the standings are always correct.

TV Display

Show pairings and live standings on a TV or projector with one link, in several clean visual themes.

Trusted by organizers in 50+ countries

Swiss software anyone can use

Most Swiss chess software is built for arbiters and assumes you know the pairing rules. ChessHost is the opposite. There is no install, no spreadsheet, and no pairing knowledge required. Enter the results and the next Swiss round appears instantly, correct and ready to display or print.

It runs in any browser on a laptop, tablet, or phone, so you can run the whole Swiss event from one device. And because it is free forever with no credit card, you can run a complete Swiss tournament without ever reaching for a payment form.

Run a Swiss event free

Set up a Swiss-system tournament in under two minutes and let the software pair every round. No download, no account needed.
