# Convex vs Supabase: Backend-as-a-Service Comparison

Convex is a reactive backend platform with real-time sync, serverless functions, and a document database. Supabase is an open-source Firebase alternative built on PostgreSQL with auth, storage, and edge functions.

## Detailed Comparison

| Factor | Convex | Supabase | Winner |
|--------|------|------|--------|
| Real-Time Sync | Built-in reactive queries, automatic UI updates | Real-time subscriptions via PostgreSQL LISTEN/NOTIFY | Convex |
| Database | Document database with TypeScript-first schema | Full PostgreSQL with SQL, joins, extensions | Supabase |
| Developer Experience | End-to-end TypeScript, zero-config, type-safe queries | Good DX but requires SQL knowledge, more config | Convex |
| Open Source & Self-Host | Proprietary, cloud-only | Fully open source, self-hostable | Supabase |
| Serverless Functions | Integrated mutations/actions with ACID transactions | Edge Functions (Deno) with separate deployment | Convex |

## Choose Convex when...

- Building real-time reactive applications.
- Need an integrated development approach.
- Prioritize speed and responsiveness.

## Choose Supabase when...

- Focusing on SQL-centric applications.
- Need PostgreSQL's capabilities.
- Prioritize open-source solutions.

## Our Recommendation

Convex excels in real-time reactive apps with its integrated approach. Supabase is better for SQL-centric apps needing PostgreSQL's power and open-source flexibility. Convex for DX-first real-time apps; Supabase for data-heavy PostgreSQL workloads.

## Frequently Asked Questions

**Q: Which has better DX (Developer Experience)?**
A: Convex wins for TypeScript projects with its end-to-end typing. Supabase wins for teams familiar with SQL and relational modeling.

**Q: Can I use both?**
A: Technically yes, but not recommended. Choose based on your primary needs - real-time first (Convex) or SQL/relational first (Supabase).

**Q: Which is Context Studios' preference?**
A: We use Convex for most new projects due to superior TypeScript DX and automatic real-time. We use Supabase when clients need SQL or have existing Postgres data.
