Ready to rate
Players come from the FIDE and US Chess lists as you type, so ids are right from the start. Download a TRF file for submission.
Byes, late entries, withdrawals
Add a player after round 2, give a half-point bye, or withdraw someone. The next pairing takes it into account.
Forfeits done right
Record +/-, -/+ or a double forfeit. Tiebreaks use the FIDE virtual-opponent rule and the game is left out of rating.
A public page per event
Share one link. Players and parents see pairings and standings on their phones, with no account needed.
