🔍 Detection Targets

Every AI fingerprint, exposed.

In the age of Vibe Coding, every AI tool leaves a unique trace. Vibe Code Detector reads them all.

🖥️
AI IDEs & Agents
Internal markers and signature patterns left by code-generation IDEs and autonomous agents.
Cursor Windsurf Trae Replit Agent Devin Claude Code
⚡
Generation Platforms
Deployment-specific signatures and generator meta tags embedded by AI web-building platforms.
v0.dev Lovable.dev Bolt.new Stackblitz Google AI Studio
🎨
Component DNA
Structural fingerprints from the most popular AI-default component libraries and icon sets.
Shadcn/UI Radix Lucide Icons Tailwind Framer Motion
📝
Prompt Artifacts
Leftover placeholder text, generic naming patterns, and embedded metadata that AI tools commonly inject.
Lorem Ipsum Feature 1/2/3 Bento Grid AI Comments
⚙️ How It Works

Multi-layer forensic analysis.

Each scan runs a weighted heuristic pipeline across four detection layers.

1
Utility Density Scan
Calculates the ratio of Tailwind utility classes per DOM element. A ratio above 4.5 is a strong indicator of prompt-based styling.
2
Component Fingerprinting
Identifies data-radix-* attributes combined with Shadcn CSS variables like --background and --foreground.
3
IDE Signature Matching
Scans for internal markers like __cursor, agent-specific class prefixes, and AI-generated comment blocks.
4
Final Score & Verdict
A weighted sum across all heuristics produces a 0–100 confidence score and a human-readable verdict: Human, Likely AI, or Almost Certainly AI.

📊 Heuristic Weights

Every signal, calibrated.

Each heuristic is assigned a weight based on its discriminative power. High-weight signals are rare in human code.
