What happened to the URL on file for UI Sketcher?

URL unreachable The URL on file (https://marketplace.visualstudio.com/items?itemName=pAIrprog.ui-sketcher) did not respond across three consecutive checks; the streak completed on 2026-09-28.

This reports what that URL did, not a claim that UI Sketcher itself is gone: the address on file does not confidently match UI Sketcher's own domain, so if it turns out to be a marketplace or listing page rather than UI Sketcher's own site, this observation is still accurate about the URL, just not about the product. See the methodology for how the match is made.

The vendor's own description, unedited:
UI Sketcher is an extension for Visual Studio Code that utilizes the capabilities of GPT-4 Vision to transform user interface (UI) sketches into code. Once installed, users can draw their UI on an integrated drawing board, and generate code by clicking 'Make Real'. The code is placed where the user's cursor is located in the open text file. The tool aims to offer a straightforward and time-saving way to convert UI concepts into functional code. It also allows iteration through a live preview URL, providing a real-time view of the generated user interface. Though the product hasn't been tested thoroughly across many stacks, it has shown excellent compatibility with Tailwind and Svelte. The extension also offers custom settings to tailor the generated code to the project's needs, with considerations for project packages, custom instructions, preview URL and maximum token generation. The UI Sketcher is built to handle the OpenAI API token securely, stored in a secret store managed by VSCode, ensuring user data privacy and protection.
