AI Website Builder
React
AI Coding ToolLovable and React are both popular choices, but they serve different needs. Lovable is a AI Website Builder with heavy AI involvement in the build process, 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.

AI Website Builder
Lovable is a ai website builder with an AI Score of 90/100 (AI-Native). Our detection engine uses 23 signal patterns to identify Lovable-built sites.
AI Coding Tool
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.
Lovable is an AI-powered web application builder targeted at founders, product teams, and non-technical creators who want to generate and deploy full-stack web apps through natural language prompts. Sites built with Lovable carry a distinctive technical fingerprint that AIWebsiteDetector.com's engine identifies through a combination of 5 script patterns, 4 CDN domains, 8 HTML patterns, 3 HTTP headers, and 3 meta tag patterns — making it one of the more richly signaled AI builders in our detection database. Key detection signals include characteristic HTML attributes and structural markup injected at build time, alongside CDN domain references and HTTP response headers that persist even when sites use custom domains. Script loading patterns tied to Lovable's runtime infrastructure provide particularly reliable indicators, as these are difficult to strip or obfuscate without breaking core application functionality. Lovable projects are typically hosted on Lovable's own infrastructure by default, with the option to connect custom domains — a deployment pattern that contributes to the consistency and high confidence of detections across the sites we scan.
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.
