Data Architecture & Modeling Hub
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.
100% Client-Side Privacy: Schema DDL and database structures never leave browser memory. Operations execute entirely in local browser tab memory.
