SQL to ER Diagram: paste schema, get a clean map
Paste your CREATE TABLE statements and instantly get an interactive entity-relationship diagram — runs fully in the browser, nothing uploaded anywhere.
A browser-only tool that turns SQL CREATE TABLE statements into an interactive ER diagram. It has its own SQL parser, canvas rendering tuned for hundreds of tables, and a built-in editor where changes to the code update the diagram live. Hover highlights relationships, clicking pins focus, table positions persist between sessions, and you can export to PNG or SVG. It blew up because it kills a real annoyance — visualising a schema — with zero friction and no data leaving your machine.
Why a vibe-coder should care
Anyone who has ever tried to understand a database from raw SQL knows the pain. Paste your schema, see how everything connects, and grab a clean picture for docs or a teammate — without signing up or trusting a server with your data.
