Domain Dump

Lists all domains a site contacts during its work (CDNs, scripts, XHR, etc.).

Domain Dump shows you every domain the current tab contacts while it runs: scripts, CDNs, XHR/fetch, images, fonts, iframes, WebSockets — the works. Open any site, click the extension icon, and you get a unique, deduplicated list of hosts. Toggle between root domains (eTLD+1, e.g. foo.co.uk) and full hostnames (e.g. cdn.static.foo.co.uk). Filter, copy to clipboard, or export to a text file with one click. Features: • Captures all network request types via the Chrome webRequest API • Correct eTLD+1 resolution using the Public Suffix List • Per-tab isolation — the list resets when you navigate to a new page • Filter box, copy, export to .txt, clear • The site's own domain is highlighted at the top • Dark-themed popup Privacy: Domain Dump does not collect, store, transmit, or share any data. Everything is processed locally, in the memory of the extension's service worker, and discarded when the tab is closed. The extension makes no network requests of its own — no analytics, no telemetry, no third-party SDKs. Open source (MIT license): https://github.com/yadotrof/domain-dump
