Turn any GitHub repository into a system-architecture diagram

Paste a repo URL and GitMapper analyzes its structure to render a clear, downloadable architecture map.

How it works

Paste the repo URL

Use the full format https://github.com/owner/repo. Try this example.

Add keys (optional)

Provide a GitHub token or Gemini key in Advanced settings to avoid rate limits.

Generate the diagram

We’ll render a Mermaid system-architecture map you can preview and download.
