See what any site is built with
The stack behind a URL, as JSON.

TL;DR
Send a URL to POST /technologies and get back every technology the page gives away: its CMS or shop platform, JavaScript frameworks and libraries, analytics and tag managers, CDN, web server, payment and chat providers, each with its version when the page shows it, a confidence from 0 to 100, its categories and the signals it was detected by. The page is rendered in a real browser first, so what it loads with JavaScript is found too. It costs 1 credit and calls no model.
Free plan, no credit card. 1,000 credits a month.
It reads the rendered page, its response headers, cookies, loaded scripts and JavaScript globals, and the site's DNS records, and matches them against an open database of over 7,000 fingerprints. It is also an operation of /scrape, off the same page visit as the rest, and the detect_technologies tool of the MCP server.
