The booking backend for sports venues that don't have one. Courts, halls, classes — double-booking made impossible at the database level, with a clean API ready to plug in.
The hard parts of a booking system, solved at the root.
Book half a hall? The whole court disappears. It's database physics, not a check you can forget.
60/90/120′ slots on a 30′ grid, with anti-fragmentation rules: no unsellable half-hours.
Capacity classes with an instructor, auto-generated every week, skipping closures on their own.
OpenAPI ready. Any system books with a Bearer token. Spec → generated client.
An account, a few courts, and you're online. Your branded public page is ready.
