description PostgREST Overview

PostgREST automatically generates a fully functional, RESTful API directly from a PostgreSQL database schema. It is incredibly simple to set up and requires zero boilerplate code for basic CRUD operations. While less feature-rich than dedicated BaaS platforms, its directness and reliance on a single, trusted source (Postgres) make it unbeatable for quick, reliable data exposure.

help PostgREST FAQ

What does PostgREST generate from a PostgreSQL database?

PostgREST exposes a REST API directly from a PostgreSQL schema, using tables, views, functions, and database roles as the contract. Instead of writing CRUD controllers, you design the database and let PostgREST map HTTP requests to SQL behavior.

How does PostgREST handle permissions?

PostgREST leans on PostgreSQL roles, grants, and Row Level Security rather than duplicating authorization rules in application code. That makes it powerful for teams that already understand Postgres, but risky if database permissions are sloppy.

How is PostgREST related to Supabase?

Supabase uses PostgREST as part of its auto-generated REST API layer for PostgreSQL projects. If you like Supabase's table API but want a self-hosted, database-first approach, standalone PostgREST is the underlying tool to study.

When would Hasura be a better fit than PostgREST?

Hasura is usually considered when a team wants GraphQL, event triggers, remote schemas, and a larger metadata layer. PostgREST is leaner and more direct, which suits projects where PostgreSQL itself is meant to remain the main source of truth.
