devbret/website-internal-links ? reverse-engineered prompt

Build me a web app that crawls a website starting from one URL, follows its internal links, and collects useful page data like SEO, accessibility, performance, security, and link structure. I want it to save the crawl results into a JSON file, then show the whole site as an interactive network graph where each page is a node and the links between pages are easy to explore.

I also want a clean dashboard that lets me click a page and see a scorecard with the page’s details, plus a separate analysis section that uses Claude to review the selected pages and suggest improvements. The app should run locally, crawl a set number of pages that I can choose in a config file, and then open in the browser on localhost.

Please keep it simple to set up, include a way to add my Anthropic API key, and make sure the frontend and backend work together smoothly. If you need to look up current docs online while building it, go ahead.
