FREE SQL-TO-ER DIAGRAM TOOL RUNS ENTIRELY IN BROWSER

The tool at sqltoerdiagram.com allows developers to paste SQL code and instantly generate corresponding ER diagrams. Since all processing happens client-side, no SQL statements or schema information leaves the user's browser. Features include support for standard SQL syntax and automatic diagram generation without manual configuration. The minimalist approach removes barriers to quick schema visualization, useful for documentation, onboarding, or understanding existing database structures. The project has gained traction on Hacker News with 145 points and 27 comments, suggesting developer interest in privacy-preserving tools. It addresses a common workflow where teams need to diagram databases but may hesitate uploading proprietary schemas to third-party services. No installation or authentication required—users simply visit the website and begin converting SQL immediately.
