About the What’s that site running?

Find out what a website is built with: CDN, hosting, server, CMS, framework, JavaScript libraries, fonts, analytics, ad pixels, chat and payments, plus the email and business apps its DNS reveals. Every result shows the clue that gave it away.

Every result comes in two styles: plain English for everyone, and the exact technical detail for engineers, with the raw JSON one click away.

Questions

From the home page only: response headers, cookie names (never values), meta tags, script and style addresses, preconnect and dns-prefetch hints, URLs inside inline scripts, and public DNS (CNAME, MX, SPF and TXT verification records).

No. We read one page and match the addresses it mentions. Nothing from the other companies is downloaded or run.

Some tools load later (after a click or consent), live behind a login, or hide behind a CDN. Detection only sees public clues on the first page.

Public websites on the normal web ports (80 and 443) only. Private, local and IP addresses, and logins in the address, are refused, and every redirect is checked the same way.
