Technology Detector
Detect web technologies, frameworks, CMS, CDNs, and analytics from any URL.
A technology detector identifies the software powering a website — its CMS, JavaScript framework, web server, CDN, analytics, and e-commerce platform. This tool fetches a URL and inspects its HTML and response headers for tell-tale signatures, reporting each technology with a confidence level. Use it for competitive research, due diligence, or simply to learn how a site is built.
Frequently asked questions
How does technology detection work?
It matches patterns in a page’s HTML, scripts, and HTTP headers against known fingerprints for frameworks, servers, and tools.
Why might a detection be wrong or missing?
Sites can hide headers, sit behind a CDN that masks the origin, or load tools dynamically, so detection is best-effort rather than definitive.
Can it detect the server behind a CDN?
Often not — a CDN like Cloudflare replaces origin headers, so only the CDN is visible.
What does the confidence level mean?
High confidence comes from a strong, unique signal such as a generator tag; medium from a looser match that could have other explanations.
Is this like Wappalyzer?
It works on the same principle of signature matching, covering common CMSs, frameworks, servers, CDNs, and analytics.
