Where your clients, classes and check-ins actually live.
Databases & backends
Postgres database, logins and row-level security for client data.
verdict › The default backend for AI-built fitness apps. Turn on row-level security or your clients can read each other.
Free tier is plenty for one gym; Pro for production.
supabase.com ↗Databases & backends
Google's database, auth and hosting for web and mobile apps.
verdict › Fine choice, but most AI builders and kits assume Supabase. Swim with the current.
Generous free Spark plan; pay-as-you-go Blaze.
firebase.google.com ↗Databases & backends
Serverless Postgres with branching, for when you want just a database.
verdict › Clean Postgres. You'll add your own logins and rules, so more work than Supabase.
Free tier; usage-based paid plans.
neon.tech ↗Databases & backends
Spreadsheet-database for class rosters, leads and member lists.
verdict › Perfect back office for a small team. Not a client-facing database at scale.
Free tier; paid per seat.
