Manual ERD editing
Add tables, define columns, set keys, and adjust structure directly on the canvas.
ERD generator
Create ERD diagrams online from scratch or from imported SQL.
Use DataPilot ERD to sketch new schemas, import DDL, organize tables visually, and keep one browser-based entity relationship diagram that is easier to review than raw SQL alone.
SQL import
Paste SQL to generate the first version of your model faster instead of redrawing everything.
Shareable workspaces
Open the same diagram with other people for review and discussion.
When to use a free ERD generator
- You are designing a new schema and want a visual draft before implementation.
- You inherited SQL scripts and need a faster way to inspect the structure.
- You need one shareable diagram for onboarding, discussion, or review.
Review structure quickly
Keep one diagram open while engineers, analysts, and product stakeholders align on table boundaries and naming.
Refine before implementation
Adjust relationships and field definitions before a schema reaches migrations, test data, or downstream reporting work.
Share the current model
Use one workspace as the visual reference instead of sending disconnected screenshots or fragments of DDL.
