Git as in the version control system "Git" & Closer as in "how close one is"

🔎 Find how close you are to another GitHub user in less than 20 seconds

GitCloser Bi-directional BFS algorithm is located at /backend/algorithm

GitCloser is a web application that makes it super easy to find out how close you are to another GitHub user. It utilizes a Bidirectional Breadth First Search (BFS) algorithm to find the (mostly shortest) path between two users on GitHub. Implemented in Go with go routines for concurrency, the algorithm takes around 20 seconds or less for most users on GitHub.

You can try it out at gitcloser.hayasaka.moe without deploying anything youself - just type in two GitHub usernames and click "Find Path"! If you want to self host it though, it'll take a bit of configuration.
