About

Fingerprints the technologies powering a website by analyzing its HTML, inline and external scripts, response headers and cookies. Detects JavaScript frameworks (Next.js, Nuxt, Astro, Remix…), CMS and site builders (WordPress, Shopify, Webflow…), e-commerce platforms, analytics and tag managers, ad and marketing pixels, live-chat widgets, A/B-testing tools, payment providers, CDNs, hosting platforms, web servers, fonts, video players, security/anti-bot vendors and error trackers — 150+ signatures in total.

Each detection includes the category, a confidence level and the evidence strings that triggered it, plus a category-grouped summary and interesting response headers. Detection uses the fetched HTML plus one lightweight header probe per site.
