NexusUI

What NexusUI is
NexusUI is a free, open-source web tool that turns screenshots, mockups, and wireframes into editable React code with Tailwind CSS styling. It produces TypeScript components and can organize code for frameworks such as Next.js, including splitting components automatically. The generated interface has an interactive preview powered by Sandpack, where users can edit TSX in the browser with Monaco and Sandpack. The preview can be resized for mobile, tablet, and desktop, and the tool describes its output as using responsive flex and grid layouts. Uploads accept PNG, JPG, and WEBP images up to 10 MB. Users can copy or export generated code to their own repository. NexusUI supports React, Next.js, Tailwind CSS, and TypeScript. Its site links to local setup instructions; running it locally requires Node.js 18 or later and a valid Gemini API key. The documentation says API routes use the key server-side only, and advises checking quotas and key validity if generation fails.
