Counted over GitDiagram's stored diagrams of public repositories, from the names their components and groups carry and the files they link to; the rules are the ones in the 2026 open-source architecture report. Stars are GitHub's when the diagram was last made. Rebuilt daily: hubs grow as more repositories' languages are known.
