Vibe-Code Checker is a free Chrome extension designed to detect the AI-generated content of websites. By providing a Vibe Score ranging from 0 to 100, it enables users to understand the balance between human-crafted and AI-assisted elements on any given site. The extension operates seamlessly in the background, automatically scanning web pages and updating its score in real-time. Users can click on the icon to access a detailed breakdown of the analysis, which examines over 15 signals including AI phrases, unoptimized code, and hosting platforms.

In addition to scoring, Vibe-Code Checker offers tech stack detection, identifying technologies used in the development of a site, such as frameworks and CSS libraries. It features an analytics dashboard that tracks scores across multiple sites, allowing for comparisons and insights into web development trends. The extension prioritizes user privacy, as it processes all data locally within the browser, ensuring no information is sent to external servers. With no limitations or sign-ups required, Vibe-Code Checker is an accessible tool for anyone interested in web technology.
