Pairings without the paperwork
ChessHost generates correct pairings every round so you never touch a pairing chart again.
Automatic Pairings
Pair every round in Swiss, Round Robin, or Knockout. Opponents and colors are chosen for you and repeats are avoided.
Byes Handled
With an odd number of players, the bye is assigned automatically and fairly each round, with no tracking on your part.
Tiebreaks & Standings
Scores, tiebreaks, and rankings recalculate after every round, so standings are always correct and ready to share.
Print or Display
Show the current pairings on a TV or projector, or hand players a read-only link to find their board.
Correct pairings, zero spreadsheets
Pairing by hand means tracking every player's score, color, and past opponents, round after round. ChessHost does all of it for free. There is no install, no spreadsheet, and no pairing chart. Enter the results and the next round's pairings appear instantly, correct and ready to display or print.
It runs in any browser on a laptop, tablet, or phone, so you can pair the whole event from one device. And because it is free forever with no credit card, you can pair a full tournament without ever reaching for a payment form.
