The decision, in plain words
For a solo builder at 5,000 monthly active users and a $50.00/mo budget for the database slot, Supabase leads at 95% fit and $25.00/mo. The two rules doing the work: budget fit (~$25/mo is 50% of your $50/mo budget); batteries included (Bundles auth, file storage, realtime — fewer services to glue at team size 1).
The gap to Convex (76% fit) is wide at these inputs — you'd need to change your requirements, not your taste, to flip it.

People also ask
Can I use Convex with React Native?
Yes — Convex ships a React client that works with React Native/Expo, and its realtime-by-default model suits mobile sync. The consideration isn't compatibility, it's the data layer: queries are TypeScript functions on Convex's document store, not SQL.
Can I use Supabase for free?
Yes — the free tier includes a 500MB database, 50K monthly auth users, 1GB file storage and 5GB egress across 2 projects (verified 2026-07-15). The catch: free projects pause after 1 week of inactivity, so it suits actively-used apps, not parked demos.
