Vibe Coding Detector - by A5

Overview

Vibe Coding Detector - by A5 is a Chrome extension that helps you determine whether a website was likely created using AI or automated site-generation tools. It analyzes real, concrete signals in a page’s code, structure, metadata, and visible text to estimate how likely the site was “vibe coded.”

Built for developers, researchers, and curious builders who want explainable results, not black-box guesses.

Key Features

• AI-generation detection: Identify signals commonly associated with AI- or template-generated websites
• Clear verdicts: Get a Likely, Unclear, or Unlikely determination
• Confidence scoring: See a 0-100% confidence score for each analysis
• Explainable reasons: Understand exactly which indicators were detected
• Debug breakdown: Optional detailed view of matched rules and scoring
• Local analysis: Runs entirely in your browser with no cloud uploads
• Read-only inspection: Never modifies page content or behavior
