Find out which CMS, frameworks, analytics and server a website uses.
The website technology checker looks at the HTML and HTTP headers of a site to detect the technologies behind it: the CMS or website builder, JavaScript frameworks, e-commerce platform, analytics and marketing tags, CDN, hosting and web server.
It's handy to research competitors, qualify leads or understand how a website was made before redesigning it.
CMS, builders, frameworks, analytics, CDNs and more.
Shown when the site reveals them.
Web server, IP address, location and HTTP version.
Grouped for a quick overview.
Each technology leaves traces: file paths, meta generator tags, cookies or HTTP headers.
Some sites hide their stack, or load tools only after a click or consent. Detection reads the first page load.
Often, from the server headers and the IP location shown in the Server section.
