AI Coding ToolWordPress and React are both popular choices, but they serve different needs. WordPress is a CMS with a traditional, manual approach to building, while React is a AI Coding Tool 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.

React is a ai coding tool with an AI Score of 65/100 (AI-Assisted). Our detection engine uses 11 signal patterns to identify React-built sites.
WordPress is an open-source content management system powering everything from personal blogs to large-scale enterprise websites, making it the most widely deployed CMS on the web and a primary target for accurate fingerprinting. AIWebsiteDetector.com identifies WordPress installations using a layered set of technical signals, including 3 distinct script patterns, 2 HTML structural patterns, 2 HTTP response headers, 2 meta tag patterns, and 1 CDN domain reference — collectively providing high-confidence detection across both default and heavily customized deployments. These signals typically manifest as characteristic markup in page source, identifiable request headers returned by the server, and script references tied to WordPress core or its content delivery infrastructure. Because WordPress supports thousands of themes and plugins that can obscure surface-level indicators, the multi-signal approach ensures reliable identification even when administrators attempt to minimize the platform's visible footprint. WordPress itself is free and open-source, but hosting costs vary widely — from shared environments to managed WordPress hosting — meaning the same CMS signature can appear across dramatically different infrastructure setups, a nuance the detection engine accounts for when evaluating header and CDN patterns.
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.
