Website Technology Checker
Enter an address to see the CMS, framework, server and analytics technology a site runs, with evidence.
This tool reads the HTML source and the response headers your browser would normally receive from the address you enter, then works out which technologies power the site. It searches six categories: content management and e-commerce platforms, frameworks and libraries, server or CDN infrastructure, analytics and marketing scripts, live chat tools, and payment providers. Every finding traces back to something concrete, a meta generator tag, a script address, a response header or a cookie name, the tool reports what it sees rather than guessing from how a page looks.
Results arrive grouped by category; each line names the technology, the evidence behind it, a generator tag, a script address, a response header or a cookie name, and a confidence level. A certain finding comes from a generator tag or a header unique to that technology; a likely finding rests on a single indirect trace and can turn out wrong. Version numbers only appear when the page itself states them; the tool never produces a score out of a hundred, it simply lists what it found.
The tool only reads the HTML your server returns and the headers that come with it; it cannot see traces added later by JavaScript, deliberately hidden setups, or backend software that leaves no external mark. An empty category does not always mean the technology is absent, the trace may be hidden or missing from the signature list. When nothing stands out the tool says so rather than guessing, and for certainty, say for a contract, asking the site owner directly is the most reliable route.
FAQ
Does it show version numbers too?
Only when the page itself states the version explicitly; otherwise no version is guessed, only the technology's presence is reported.
If a technology isn't found, does that mean it isn't used?
No, the tool reads the HTML and headers your server returns; a trace can be hidden or loaded later by JavaScript and stay invisible. In that case the tool reports no clear trace rather than claiming it is absent.
What is the difference between a certain and a likely finding?
Certain comes from direct evidence such as a generator tag or a header unique to that technology; likely rests on a single indirect trace and can turn out to be wrong.
Is the address I enter stored anywhere?
The address is not stored permanently; if the same one is checked again shortly after, the result stays in server memory for about ten minutes to answer faster, then it is cleared.
