Vibe Coding Detector is a free Chrome extension designed to help users determine whether a website was created using AI or automated site builders. By analyzing a webpage's HTML, structure, metadata, and visible content, this tool provides a clear assessment of the likelihood that a site was 'vibe coded'. The extension operates entirely within the browser, ensuring user privacy and data security without reliance on external servers.

The tool offers users a verdict indicating the likelihood of AI involvement (Likely, Unclear, Unlikely), along with a confidence score ranging from 0 to 100%. Additionally, it provides specific reasons for its conclusions and an optional debug breakdown for users seeking deeper insights. Vibe Coding Detector is ideal for developers and researchers interested in understanding the digital footprint of AI-generated websites.
