A simple web-based scraping tool that allows you to extract data from websites using CSS selectors.

Web Scraper leverages Puter.js to overcome the fundamental challenge of cross-origin requests in web browsers. Traditional web applications are restricted by CORS (Cross-Origin Resource Sharing) policies, which prevent direct requests to external domains from browser-based JavaScript.
Specifically, Web Scraper uses puter.net.fetch() to make cross-origin HTTP requests and bypass CORS restrictions without needing a proxy server. This allows the app to scrape public websites without server-side configuration.
The scraped HTML is then parsed using the browser's built-in DOMParser API, and data is extracted using standard CSS selectors via querySelectorAll().
