Design SQL schemas through a modern native window, intuitive visual interface. A lightweight yet powerful diagramming tool built for speed and simplicity.

No steep learning curve. Just visual database design.
Paste an existing SQL script to reverse-engineer a diagram instantly, or simply drag-and-drop tables to start designing from scratch.
Define columns, data types, and relationships using the visual editor. Use auto-layout and colored regions to keep your logic organized.
Turn your schema into professional documentation. Export high-resolution PNG images with smart cropping. Perfect for presentations, wikis, and team reviews.
From reverse-engineering legacy code to organizing complex schemas, get the clarity you need without the clutter.
Dont start from scratch. Simply paste your existing CREATE TABLE scripts into the import dialog. SQL Schema analyzes your code and automatically generates the visual Entity Relationship Diagram for you.
Define columns, data types, and primary keys without wrestling with complex menus. The clean editor allows you to modify table structures quickly, ensuring your schema is precise and production-ready.
Link your data effortlessly. Whether its One-to-Many or Many-to-Many, just drag lines between tables. Configure foreign keys and cardinality constraints visually instead of writing manual ALTER TABLE syntax.
Complex databases can get messy. Use Regions to group related tables (like 'Sales' or 'Inventory') into color-coded zones. Keep your business logic separated and your diagram easy to read.
