ERD Tool

Online ERD tool for visual database diagrams.

ERD Studio helps teams design database diagrams in the browser while keeping DBML as the source. Use it when you need an ERD editor, ERD viewer, or schema review workspace that supports both visual editing and source editing.

Use Cases

What this workflow is for.

01

Create database tables visually on a canvas.

02

Review foreign key relationships with detailed or simplified relation views.

03

Export diagrams or share a read-only ERD link with reviewers.

04

Use category colors to keep large ERDs easier to scan.

Workflow

How ERD Studio supports it.

Visual editing for database tables

Create tables, add columns inline, edit names and types, and connect relationships without leaving the canvas.

Relationship review built into the canvas

Switch between detailed relationship notation and simple relation lines depending on whether you are modeling or reviewing.

Source-aware ERD workflow

The diagram is connected to DBML, so visual changes and source changes remain part of the same schema workflow.
