DB Schema Visualizer
Paste your SQL CREATE TABLE statements to instantly generate an interactive ERD diagram.
About the DB Schema Visualizer
The DB Schema Visualizer by Grab-Kit is a free online tool designed for backend developers, database administrators, and software architects. Entity-Relationship Diagrams (ERDs) are the standard way to visualize database structures, showing tables, columns, data types, and the relationships between them via foreign keys. Generating these diagrams manually in drawing software is tedious, and enterprise tools are often expensive. Our tool bridges this gap by converting raw SQL code into a visual diagram instantly.
Using the tool is incredibly straightforward. Paste your SQL CREATE TABLE statements into the left input box. The tool's parser analyzes the SQL to extract table names, column types, primary keys, and foreign key constraints. It then uses Mermaid.js to render a clean, interactive ERD diagram on the right. You can click and drag the tables to rearrange them, and use the "Export as PNG" button to download a high-quality image of your schema for your documentation or presentations.
