Green Jacket
Multi-tournament fantasy golf for people who already have a group chat about it. Start a club, run a pool for each major, invite your people, and watch the leaderboard move in real time.
Live.
It is running, people use it, and we still work on it.
Where it came from
There was always a Masters pool in the family. It ran on paper, then on a spreadsheet, and eventually the spreadsheet stopped coping — a player withdraws, a tee time moves, and somebody is up late rewriting formulas while everyone else watches the golf. So the person who had been maintaining it learned to code and rebuilt it as software. It has grown every season since, and this year it carried pools for all four majors rather than only Augusta. Trips, a weekend container for group golf trips, is rolling out next.
How it is built
Next.js and React on Vercel with Convex as the backend, which is what makes the live leaderboard live: scores stream to every client as they change rather than being polled. Clerk handles accounts, Resend sends the pool mail, and the whole thing has carried pools through all four of the season's majors since it went live in April.
A pool for The Masters: entry, purse and final standings in one view. Entrant names are blurred here, not in the product.
The leaderboard. Scoring follows the live field, so nobody is editing a spreadsheet during the tournament.
A club holds a pool for each major. Invite-only, and private by default.
Trips, rolling out now: a weekend of golf with friends, run like a tour event.
