How it works

1

Choose a Repository

Enter any public GitHub URL, browse open source projects, or connect your GitHub account to access private repos.

2

Automatic Analysis

Headlamp indexes your repository, maps dependencies, detects patterns, and writes documentation for you automatically.

3

Explore & Understand

Browse code, read the generated docs, visualize dependencies, and chat with an AI that understands the entire codebase.

Powerful features for code understanding

Everything you need to quickly understand and navigate any codebase
