HTML/CSS Website Scraper Extension
A Chrome extension that scrapes and exports renderable HTML/CSS from any webpage so developers and designers can clone layouts for use in Cursor, v0, or other AI coding tools.
▶ WATCH THE SOURCE SEGMENT — Do this to build a $100k/mo chrome extension using AI (Cursor AI, Claude)01 THE IDEA
The specific extension built in the video scrapes the full HTML and CSS of any active browser tab and exports it as a standalone renderable file that can be pasted directly into an HTML editor or fed into AI coding assistants like Cursor or v0. This solves a real workflow pain point for developers and designers who want to reference or remix existing web layouts without manually inspecting elements.
The tool was built in under 30 minutes using Claude for code generation and Cursor for file management — demonstrating the speed possible with AI tooling. The extension works on most sites (Twitter/X, Wikipedia, NYT, Arc) but is blocked by sites with strict Content Security Policies like YouTube. Publishing to the Chrome Store requires only a $5 one-time developer fee, and the extension structure (manifest.json, popup.html, popup.js, background.js) is a reusable template for future extensions.

03 THE VERDICT
This is a genuinely useful developer tool with a clear, underserved niche at the intersection of AI coding assistants and web design cloning. The build time is measured in hours, the distribution cost is $5, and the target user (AI-assisted developer) is the fastest-growing segment in tech right now. Add a freemium model with premium features like AI-powered component extraction and this could easily reach $10K+/mo.
