ER diagrams that run in the browser. No server, no account, no friction.

Most database schema tools require a running server or a paid account just to render an ER diagram. We wanted something that works instantly — paste your SQL schema, get a clean visual diagram, done.

Built with Rust compiled to WebAssembly, diagram.rs parses SQL DDL (CREATE TABLE statements) and runs a layout algorithm entirely client-side. Every render happens in your browser. No data leaves your machine.

The renderer handles foreign key relationships, composite keys, and multi-schema DDL files. The output is clean and export-friendly — built for engineers who need to communicate schema structure quickly, not for making slides.
