Hasura vs Supabase: Which MCP should you use?

⚡

Hasura

Instant GraphQL API over Postgres

VS
🟢

Supabase

Open-source Firebase alternative on Postgres

TL;DR

Hasura gives you instant GraphQL + REST API over Postgres (or MySQL, SQL Server) with deep permission rules. Supabase gives you auto-REST (PostgREST) plus auth, storage, edge functions, realtime — broader but less GraphQL-native. Hasura wins for GraphQL-first teams; Supabase wins as a full BaaS.

Migration path

You can run Hasura on top of Supabase's Postgres — point Hasura Cloud at the Supabase database connection string. This gives you GraphQL on Supabase. Going the other way (remove Hasura, use Supabase's auto-APIs) requires rewriting GraphQL queries as PostgREST calls or pg_graphql queries. Auth layer usually needs a rewrite either way.
