Our Recommendation
Choose Supabase for PostgreSQL and broad ecosystem support. Pick Convex for the best TypeScript developer experience with reactive data.
“The best tool depends on what you are building and how you work. There is no universal winner. Pick the one that fits your workflow and budget, then ship something.”
When to Choose Each Tool
Choose Supabase
Want PostgreSQL with a large ecosystem
Choose Convex
Prioritise TypeScript DX and reactive queries
Overview
Supabase and Convex are both backend platforms but differ philosophically. Supabase builds on PostgreSQL, providing a familiar relational database with auth, storage, and edge functions. Convex provides a custom reactive database with TypeScript-first development, where queries automatically update when underlying data changes. Supabase is the safer, more established choice; Convex offers a more modern development experience.
When to Choose Each
Choose Supabase if you want PostgreSQL, need to use existing PostgreSQL tools, or are working with AI builders like Lovable that integrate with Supabase. Choose Convex if you are building a new TypeScript application and want the best possible developer experience with automatic reactivity.
Frequently Asked Questions
Can I use SQL with Convex?
No. Convex uses TypeScript functions for queries. If you want SQL, choose Supabase.
Which is more popular?
Supabase has significantly larger adoption, more tutorials, and broader ecosystem support.
Which has better real-time?
Convex's reactive queries are more elegant and automatic. Supabase's real-time requires explicit channel subscriptions.
