Fortran project architecture examples

Interactive architecture diagrams of 60 open-source Fortran repositories with a GitDiagram architecture diagram, most stars first. Each diagram shows the project's main components, how they connect, and links every part to its file on GitHub.

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.
