Hasura
Instant GraphQL API over Postgres
Supabase
Open-source Firebase alternative on Postgres
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.
Pick Hasura when you want first-class GraphQL over an existing DB with rich permissions.
Pick Supabase when you want a full BaaS (auth, storage, realtime) and auto-REST is enough.

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.

Yes. Both have MCP servers installable via MCPizy (mcpizy install hasura and mcpizy install supabase). They work identically across Claude Code, Claude Desktop, Cursor, Windsurf, and any other MCP-compatible client. You can install both side by side and route queries in your agent's prompt.
Supabase is a Postgres-based BaaS with auth, storage, and realtime. PlanetScale is serverless MySQL (Vitess) with branching, schema workflows, and massive horizontal scale. Supabase gives you a full backend; PlanetScale gives you a bulletproof MySQL database.
Firebase is the Google BaaS — Firestore, Auth, Cloud Functions, FCM, Remote Config. Appwrite is the open-source alternative — self-hostable, similar feature set, permissive license. For Google-tied mobile teams, Firebase. For self-host / open-source, Appwrite.
