Show HN: Erdus – Universal ERD Converter (SQL, Prisma, JSON Schema)

1 point

9 months ago

I built an open-source tool called Erdus to solve the pain of moving between ER diagrams, SQL, and ORMs like Prisma.

It uses a strict Intermediate Representation (IR) to unify models and detect information loss. Right now it supports: - ERDPlus (old/new) ↔ IR - IR → PostgreSQL DDL - IR → Prisma schema - Loss report when features don’t map (e.g. CHECK constraints in Prisma)

Would love feedback from the HN community.
