Scan every page of a site (or sitemap) for a word — see which pages have it and how many times.
The web version gets blocked by CORS on most sites. The extension fetches pages directly — no proxies, no block pages, just works.
Download Extension (.zip)Documents).chrome://extensions in a new tab.edge://extensions in a new tab.Browsers block cross-origin fetch() from regular web pages — this is the CORS rule and it can't be turned off. Public proxies (corsproxy.io, allorigins, etc.) get rate-limited or blocked by every modern WAF.
Browser extensions with host_permissions are exempt from CORS. The extension fetches pages exactly as your browser does when you visit them — no proxy in the middle, no block pages, no surprises.
