ERDHubDatabase Diagram Editor

Design, visualize, and collaborate on database schemas with a powerful DSL editor and live ERD canvas.

DSL-First Design

Define your schema in a clean, readable DSL syntax. Tables, columns, relationships, enums, indexes — all in code.

See your schema rendered as an interactive entity-relationship diagram in real time. Drag, zoom, and export.

Export production-ready DDL for PostgreSQL, MySQL, SQL Server, and SQLite with dialect-specific handling.

Edit diagrams together with live cursors, presence indicators, and CRDT-powered conflict-free syncing.
