Detect PostgreSQL in any GitHub repo

PostgreSQL is the advanced open-source relational database, known for reliability, extensions and standards compliance.

Why show PostgreSQL on your README

Showing Postgres next to the ORM (Prisma, Drizzle, SQLAlchemy) gives a complete picture of the persistence layer.

How PostgreSQL is detected

Stack Fingerprint reads the repo's full file tree in one GitHub API call and flags PostgreSQL when it finds any of these:

  • Files or folders: pg.config.js, postgresql.conf
  • Dependencies in package.json: pg, postgres
  • Dependencies in Python (requirements.txt / pyproject.toml): psycopg2, psycopg2-binary, asyncpg

PostgreSQL README badge

A static badge you can paste anywhere in Markdown:

![PostgreSQL](https://img.shields.io/badge/PostgreSQL-4169E1?style=for-the-badge&logo=postgresql&logoColor=white)

Or let the repo describe itself

Static badges go stale the moment you swap a dependency. A Stack Fingerprint card is generated from the repo, so PostgreSQL (and everything around it) appears or disappears on its own:

Replace OWNER/REPO with your repository, or open the builder to pick a theme and layout.
