Online SQL Schema Visualizer & ER Diagram Tool
Instantly convert raw SQL CREATE TABLE statements into an interactive Entity Relationship (ER) Diagram. Visualizing your database structure helps you spot missing foreign keys, understand relationships, and communicate your architecture to your team.
Supports MySQL, PostgreSQL, and SQLite syntax. No sign-up required everything runs locally in your browser.
Auto-Relationships
Our engine intelligently detects relationships. If you don't explicitly define a FOREIGN KEY, we heuristically link columns nameduser_id to the users table automatically.

Frequently Asked Questions
How do I verify relationships?
Hover over any table or connection line. The related tables and the connecting line will highlight in purple, while unrelated tables fade out. This helps isolate dependencies in spaghetti schemas.
Is my schema private?
Yes. All parsing and rendering happens client-side using JavaScript. Your proprietary database structure is never sent to our servers.
