Neither approach is objectively better; it depends on where your team is more comfortable reasoning about access control.

A table would be ideal

- You need full SQL power (complex queries, joins, aggregations, stored procedures)
- Your team already knows PostgreSQL and wants to stay in that ecosystem
- Self-hosting or data-residency compliance is a requirement
- You are building a product with a large and growing dataset where analytical queries matter

You are building a product with a large and growing dataset where analytical queries matter

This is debatable. PostgreSQL can't handle this well for large dataset. It requires a different tool (ClickHouse). Convex can argue they intentionally not provide incomplete solution.

Both platforms support vector search. Supabase uses the `pgvector` PostgreSQL extension; Convex has built-in vector storage alongside its document database. Convex's reactive model is an advantage for AI apps that need real-time data updates (e.g., streaming chat with live context), while Supabase's full Postgres gives more flexibility for complex retrieval pipelines and hybrid search.

As a fair comparison, it's ideal to list some 3rd migration articles coming from both side

Supabase -> Convex
Convex -> Supabase

**Supabase → Convex**

- [Migrating from Supabase and Prisma to Convex](https://dev.to/ricardogesteves/migrating-from-supabase-and-prisma-accelerate-to-convex-jdk) – community walkthrough on dev.to
- [Is BaaS enterprise-ready? Hands-on review of Convex and Supabase](https://senacor.blog/is-backend-as-a-service-baas-enterprise-ready-a-hands-on-review-of-convex-and-supabase/) – independent engineering blog comparison

This is not a migration post, instead it's a comparison post like us. Not worth putting here.
