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.

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.

SQL DDL → Diagram Notations

Parse CREATE TABLE definitions and emit Mermaid erDiagram, DBML, or PlantUML code.

SQL DDL Input (CREATE TABLE statements)

Diagram Code Output (MERMAID)

    TEAMS ||--o{ MEMBERSHIPS : "team_id"

    USERS {
        int id PK
        string name
        string email UK
        datetime created_at
    }
    TEAMS {
        int id PK
        string team_name
        string plan
    }
    MEMBERSHIPS {

        int team_id PK,FK
        string role
