gitdiagram.comAbout GitDiagram
GitDiagram turns any GitHub repository into an interactive architecture diagram, which is the fastest way to get oriented in a codebase you did not write. You paste a repository URL, or simply replace 'hub' with 'diagram' in any GitHub URL, and it generates a visualization of how the project is structured and how its parts relate. The diagram is interactive rather than a static image, so you can explore the structure instead of squinting at a rendered PNG, and the site provides example repositories such as FastAPI, Streamlit, Flask, api-analytics, and Monkeytype so you can see the output quality before pointing it at your own code. Private repositories are supported by supplying your own API key. The utility is mostly in the first ten minutes of contact with unfamiliar code: evaluating a dependency before adopting it, onboarding onto a new team's service, reviewing an open-source project you are about to contribute to, or producing an architecture overview for documentation without hand-drawing one that goes stale immediately. Because the URL-substitution trick works on any GitHub link, it also fits naturally into the way people already share repositories — no install step, no local setup, nothing to configure. The project is made by Ahmed Khaleel, is open source, and is funded through GitHub sponsorship and a single sponsor slot on the site rather than a subscription.
