Hardcore Gym is a self-hostable backend for gym and fitness studio chains. Member signups, plan structures, biometric attendance, renewals, and dues all flow through one API. Built for owners who refused to keep their member database on someone else’s SaaS dashboard.
Most gym software is rented, monthly fees, member data locked into someone else’s cloud, no API access if the owner wants to build their own app or do payroll integration. For multi-branch gym chains, that is a recipe for vendor lock-in on the most valuable asset they have: their member list.
A server-first gym management platform with a clean API surface. Member, plan, attendance, and payment entities are all first-class with full CRUD. Branch managers get web interfaces; owners get raw data access. Biometric check-in devices integrate over standard webhook endpoints.
