Convex is TypeScript-native realtime backend with tightly-integrated functions + DB. Supabase is Postgres-first BaaS with auth + storage + realtime. Pick Convex for TS-first realtime, Supabase for SQL-first apps.

## At a glance

| Dimension | Convex | Supabase |
|---|---|---|
| Primary language | TypeScript-native | SQL + any client |
| Database | Document-style with ACID transactions | **Postgres** ✓ |
| Realtime | **First class — every query is reactive** ✓ | Realtime channels |
| Function model | **TypeScript functions tightly coupled to DB** ✓ | Edge functions (Deno) |
| Auth | Built-in + integrations | Built-in (Supabase Auth) |
| Storage | Built-in | Built-in |
| pgvector / embeddings | Vector index built in | Postgres pgvector |
| Ops complexity | **Lightest — single platform** ✓ | Postgres + extensions to manage |
| Best for | TypeScript-first realtime apps | SQL-first apps with broad BaaS |

## Verdict

Convex is the right pick for TypeScript-first apps where realtime is core — every query is reactive by default, functions are tightly coupled to the DB, and operations are simpler than running Postgres. Supabase is the right pick for SQL-first apps that want a familiar Postgres + auth + storage + realtime + edge stack. For Next.js apps with heavy realtime requirements, Convex. For traditional SQL backend with the standard BaaS surface, Supabase.

## When to pick which

- **Convex** — TypeScript-first realtime apps, single-platform simplicity.
- **Supabase** — SQL-first apps, broad BaaS, Postgres familiarity.
