What does SQL Schema Visualizer do?
Turn PostgreSQL, MySQL, or SQLite CREATE TABLE statements into a clear database diagram. The SQL schema visualizer maps tables, columns, data types, primary keys, foreign keys, and references so you can understand a data model without tracing raw DDL by hand.
Start from a curated database schema template or paste your own SQL. Parsing runs entirely in the browser, so private database definitions stay on your device.
Generate an organized database diagram from common CREATE TABLE syntax.
Search tables and inspect column types, primary keys, foreign keys, and relationships.
Use SaaS, e-commerce, content, project management, social, and authentication schema templates.
Copy Mermaid ER source or export the visible schema as an SVG diagram.
Common use cases
Planning a new relational database
Understanding an unfamiliar SQL schema
Documenting table relationships
Creating an ER diagram for technical review

Everything you need to know before processing your files.
It parses common terminated CREATE TABLE statements used by PostgreSQL, MySQL, and SQLite. It is intended for schema exploration rather than full dialect validation, so procedures, triggers, and ALTER TABLE statements are not rendered.
