drawdb-io/drawdb ? reverse-engineered prompt

Build me a simple web app for designing database schemas in the browser.

I want to be able to add tables, columns, and relationships visually, then see the ER diagram update as I work. It should feel easy to use for someone who just wants to sketch a database quickly without signing up. Please include import and export for SQL scripts, and make it able to generate SQL from the diagram. I’d also like basic customization for the editor, like changing the look and layout a bit, and the ability to save my work locally so I don’t lose it.

If it makes sense, add a way to share diagrams too, but keep that optional. Make it polished, responsive, and nice to use in the browser. Look up current docs online if you need to.
