JavaScript Framework
React
JavaScript FrameworkAlpine.js and React are both popular choices, but they serve different needs. Alpine.js is a JavaScript Framework with a traditional, manual approach to building, while React is a JavaScript Framework that prioritises developer or designer control.
Below you'll find a side-by-side breakdown of detection signals, AI scores, and technical fingerprints — plus our honest take on which builder wins for different use cases.

Alpine.js is a javascript framework with an AI Score of 40/100 (No-Code / Visual Builder). Our detection engine uses 4 signal patterns to identify Alpine.js-built sites.
JavaScript Framework
React is a javascript framework with an AI Score of 40/100 (No-Code / Visual Builder). Our detection engine uses 14 signal patterns to identify React-built sites.
Alpine.js is a lightweight JavaScript framework that adds reactive, Vue-like behavior directly in HTML markup without a build step — popular with developers who want interactivity on server-rendered sites (PHP, Rails, Django, static HTML) without adopting a full SPA framework. Our engine identifies Alpine.js through 2 script patterns tied to its runtime bundle and 2 HTML patterns matching its distinctive `x-data`/`x-show`-style directive attributes, which are rarely used by any other framework and make detection highly reliable. Alpine.js is an open-source library with no hosting component of its own — detection reflects a front-end dependency, not a platform. Documented at alpinejs.dev.
React is a declarative JavaScript library developed by Meta for building interactive user interfaces, widely adopted by startups, enterprise teams, and independent developers to power everything from single-page applications to complex web platforms. AIWebsiteDetector.com identifies React-powered sites through a combination of 4 distinct script patterns, 4 CDN domains, and 3 HTML patterns — including characteristic data attributes and DOM markers that React injects during rendering. These signals are cross-referenced against known React build artifacts and CDN delivery signatures to produce reliable detections across both production-minified and development builds. Because React is a frontend library rather than a full hosting platform, it frequently appears alongside other detectable technologies such as Next.js, Vite, or Webpack, making co-detection a common and useful signal for refining confidence scores. The official React documentation and release distribution are maintained at [react.dev](https://react.dev), and its presence on a site is technology-agnostic with respect to hosting provider — meaning React is detectable regardless of whether a site runs on Vercel, Netlify, AWS, or a self-hosted server.
