PostgREST – Serve a RESTful API from Any Postgres Database

PostgREST is a tool that creates a fully RESTful API from existing PostgreSQL databases, offering a more efficient and standards-compliant alternative to custom API development. It achieves impressive performance, with subsecond response times for up to 2000 requests per second, particularly on Heroku's free tier, thanks to its Haskell foundation and optimized database interactions. Key features include security through JSON Web Tokens (JWT) for authentication, with authorization managed by database role information. It supports multiple API versions via database schemas, ensuring flexibility in table and view exposure. PostgREST also provides self-documentation using the OpenAPI standard, allowing for interactive API documentation through tools like Swagger-UI. Data integrity is maintained through declarative constraints in the database, preventing data corruption. To get started, users can download the appropriate binary from the latest release and access usage instructions via the help command. For more comprehensive information, the official documentation is available online. The project encourages community support through platforms like Patreon and welcomes contributions, with a list of sponsors and backers accessible on its GitHub page.
