A visual Entity-Relationship Diagram editor for designing database schemas, available as a web app (PWA), VS Code and IntelliJ extensions, and an embeddable framework-free custom element. It imports SQL DDL, GraphQL SDL, DBML, and AML, exports DDL for many databases, and generates code for popular languages and ORMs.

Use cases

• design a database schema visually with an ER diagram
• import an existing SQL DDL dump and turn it into a diagram
• convert a DBML file from dbdiagram.io into an ER diagram
• generate TypeScript or Java code from a database schema
• edit .erd.json schema files inside VS Code or IntelliJ
• embed an ER diagram editor in my own web app
• export a schema diagram as PNG or SQL DDL

When to choose

• you want a free, offline-capable ER diagram tool that runs in the browser or your IDE
• you need to reverse-engineer a diagram from an existing SQL dump, DBML, GraphQL SDL, or AML file
• you want one schema document format shared across web, VS Code, IntelliJ, and embedded usage
• you need code generation for many languages and ORMs from a visual schema
• you want P2P encrypted real-time collaboration on schema design without a backend

When to avoid

• you need full-fidelity round-tripping of advanced database objects like views, triggers, or stored procedures
• you require a heavyweight enterprise data modeling tool with versioned model management
• you need a general-purpose diagramming tool beyond ER diagrams (e.g., UML, flowcharts)
• your workflow depends on a specific tool's proprietary features that this editor skips on import
