Explore an interactive map of GitHub projects clustered by shared stargazers.

anvaka github io map is a browser-based visualization of GitHub repositories. The official page describes it as a map where each dot is a project, and projects within the same cluster are usually close together when many users have starred both repositories. The project README says the current map release covers 690,000+ GitHub projects and 1,500+ clusters.
Free to use in the browser. The project is available as a public GitHub Pages site with a public GitHub repository.
The map turns GitHub discovery into a spatial exploration experience. Instead of showing a search list or ranking table, it visualizes repository neighborhoods based on shared stargazers, making it easier to spot adjacent tools, languages, and communities.
