Schema Architecture & Modeling Hub

Database engineering in your browser: SQL to ER diagrams, ERD to DDL, multi-dialect translation, ORM code generation (Prisma, Django, SQLAlchemy), automated data dictionaries, and schema diffing.

Dedicated SQL to ERD Tool →
100% Client-Side Privacy: Schema DDL and database structures never leave browser memory. Operations execute entirely in local browser tab memory.

DDL → ORM Code Generator

Instantly generate Prisma Schema, Django Models, or SQLAlchemy classes from SQL DDL.

  provider = "postgresql"
