The Convex vs Supabase discussion has been picking up, but most comparisons focus on the platforms as a whole rather than how they differ specifically for AI-driven coding.

When it comes to AI coding, Convex is leagues better than Supabase.

We built a vibe-coding platform on top of Convex and it's night and day compared to vibe coding on top of a Supabase backend.

A few key reasons: -With Convex, everything is TypeScript, which agents already understand. Supabase relies on an SDK and dashboard-driven state, agents struggle with that -In Convex, backend state is fully managed and lives in the codebase alongside frontend code. In Supabase, state lives across schema, RLS policies, migrations, and dashboards. -Keeping backend state in sync across those layers is difficult for agents and often becomes the main source of breakage. -Permissions are a major failure point when they live in a separate RLS layer instead of explicit code. -Most teams use an ORM or SDK anyway, so the practical question is how small and predictable that abstraction is. -Realtime adds another coordination surface unless it is reactive by default, which Convex handles out of the box.

Also, there is the vibes aspect, Convex just feels better, faster and more modern.

We're pretty deep in Convex, built a vibe coding platform on top of it:
