How it works
We fetch the page from our server the way a browser would. Then we look at its HTML, response headers and cookies for the traces each technology leaves, such as script addresses, cookies and generator tags.
This finds what a visitor's browser receives. It can't see back-end software that leaves no trace, and some sites hide or delay their tools. We read the first 2 MB of the page and follow up to 3 redirects. Results are kept for one day, so repeat scans are quick.
