FairwayOS is golf tournament and league management software that gives course GMs, directors of golf, league coordinators, associations, charities and independent organizers one workspace to run an event from registration to results. Organizers take online registrations and payments through their own Stripe account, build pairings and tee sheets, run mobile live scoring with offline recovery, and publish real-time leaderboards for scramble, best ball, shamble, alternate shot and stroke play. They also manage sponsors and side contests, check players in on event morning, and communicate with players. Pricing is pure subscription: FairwayOS takes 0% of registration revenue, and only standard Stripe processing applies.
