Show HN: Open-Source Postgres API Generator (REST > GraphQL)

Hi HN,

We are building a GUI-based API generator for PostgreSQL that turns your database into a production-ready REST API in minutes.

Why we built it:

Every project starts with Postgres, but getting an API layer in front of it means writing boilerplate or learning GraphQL.

Hasura, Supabase, PostgREST are great — but many devs (including us) just want simple, reliable REST APIs which work with existing databases.

We wanted something open source, GUI-driven, and enterprise-ready.

What it does:

Point it at your Postgres DB → generate REST APIs instantly.

Build complex queries (deep joins and nested inserts) in a no-code GUI, deploy them as APIs.

Works with your existing schema, security, and infra.

Deploy on cloud (managed) or export your API as a NodeJS app to Github!

Open source:

Core is Apache 2.0 licensed.

Repo: https://github.com/QueryDeck/querydeck

Roadmap: support for MySQL & SQL Server next.

Try it:

Demo: https://querydeck.io/demo/

Free tier on cloud, or spin it up locally with docker run ....

We’re in beta and looking for 100 early users. Your feedback will directly shape the roadmap.

Would love to hear what you think!
