For developers and database consultants handing a schema to a client. Open one offline HTML file, paste supported PostgreSQL/MySQL table scripts, and export an interactive diagram, editable notes, printable table views and a CSV dictionary. Retains supported ALTER TABLE relationships and MySQL comments. No database connection or schema upload. $199 once; no account or key. A SQL subset, not a full database parser. Tested in Chromium on Linux. Screenshots use the built-in synthetic example.

Could you build this?
Yes It is a self-contained offline HTML/JS file that uses client-side SQL AST parsing (e.g., sql-parser) and an SVG/canvas charting library like Mermaid or vis.js to generate ER diagrams and export tables.
