Living database documentation
Move from one-off diagrams to living documentation that stays in sync with your schema, backed by a private on-premise agent.
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.
Beyond diagrams
Keep your database documented forever, not just today.
You just explored a schema. What if the whole database stayed documented — with alerts on every schema change and scheduled SQL exports — through an on-premise agent that never opens your DB to the cloud?
Schema change alerts + scheduled SQL exports
Get notified when your schema changes and schedule SQL exports without exposing the DB to the cloud.
Manual ERD editing
Add tables, define columns, set keys, and adjust structure directly on the canvas.
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.
Related ERD workflows
SQL to ERD
Convert DDL into a first visual schema and keep editing from there.
Large database schema visualizer
Isolate the relevant part of a large schema instead of reviewing the whole canvas at once.
Schema review tool
Keep review sessions organized with one shared visual reference and controlled editing.
Diagram notes
Leave sticky-note documentation and review context next to the model.
