View and Edit Static HTML file in browser editor

Feature request for product/service

Cursor Web

Describe the request

Native File Visual Prototyping Sandbox where I can open a local file like file:///home/cjb/project/mockup.html
directly in a Cursor browser tab and tweak it in real-time. This would let me polish the “look and feel” using dummy data in a low-context environment before touching any of my actual production logic.
Right now, I have to spin up throwaway Flask servers to preview a local HTML mockup.

The ultimate workflow would be a “Submit & Integrate” feature. Once I’m happy with the mockup, I could just tell Cursor to merge that design into my real app. The AI would then handle the heavy lifting—like swapping out dummy text for props or API calls—only after the UI is finalized.
