JavaScript Frameworks & Libraries
Front-end frameworks and libraries ship telltale runtime markers, react-dom, __NEXT_DATA__, ng-version, that reveal which stack a site is built on. Search for the marker to find every site using the framework.
JavaScript frameworks organize application interfaces, while libraries provide reusable behavior such as DOM manipulation, components and styling. Websites may combine several of them, so a framework search can reveal overlapping parts of a stack. Explore jQuery, React and Next.js for examples of different source signals, from recognizable filenames to generated asset directories.
To find websites using a framework, choose a technology below and inspect its query. A Next.js homepage may reference /_next/static, while a jQuery query can target jquery.min.js. Search the marker and read the surrounding script tag in each result. If your question concerns a version, use a versioned filename or a regular expression rather than the general technology name. The regex guide explains how to build that query.
Production builds can bundle code into anonymous files, and server rendering can leave little client-side evidence. A missing marker therefore does not rule out a framework. Compare visible references with CMS platforms to understand publishing tools, or explore fonts and UI toolkits for presentation assets. Stored source examples help explain a match, but do not establish which code executes on the current site.
