About this tool
Identify the CMS, JavaScript framework, server, CDN, analytics, ads, e-commerce platform and other technologies powering any website.
The detector runs a single HTTP request, then matches the response against 80+ fingerprints across CMS, JavaScript frameworks, backend stacks, web servers, CDNs, analytics, advertising, e-commerce, page builders, UI libraries, CRM, chat widgets and consent platforms. No request is made to any third-party API — detection happens entirely on the Baaed FREE SEO Suite servers.
Frequently asked questions
How does the Tech Stack Detector work? #
It fetches the page once, then runs 80+ fingerprint rules against the response headers, cookies, meta tags, script URLs and HTML markers. No data leaves the Baaed FREE SEO Suite servers.
Why didn't it detect my framework? #
Some sites serve a heavily-minified bundle or strip every framework marker for performance. If the homepage gave no signals, try a deeper page (a product, blog post, or signed-in page) where the framework usually leaves more fingerprints.
Is this the same as BuiltWith or Wappalyzer? #
Same idea — read the page and recognise the technologies — but we run the detection ourselves with no third-party calls. Coverage is narrower than BuiltWith's paid panel data but free, instant and privacy-friendly.
