vibeloc
Vibe Check Your Code — Analyze the ratio of human vs AI-generated contributions in your repository.
What is vibeloc?
vibeloc (Vibe LOC) analyzes your git history to quantify how much of your codebase was written by humans versus AI assistants like Codex, Claude Code, GitHub Copilot, Droid, and more.
Perfect for:
- 📊 Metrics teams tracking AI adoption
- 🔍 Tech leads auditing code authorship
- 🎯 Open source maintainers understanding contribution patterns
- 💡 Curious developers seeing their "vibe rate"
Quick Start
