Two measured signals: repositories that share topics (at least two), and repositories discussed in the same threads. Cards are ranked by stars gained this week.
Shares topics with
Repositories with at least two topics in common: most shared topics first. Topics are labels maintainers put on their own repositories, so they say what a project claims to be, not what its code does.
Repositories in the same collection, of a comparable size (within 5× in stars) and from a different owner, that were discussed in the same threads. Same-owner projects are excluded because they are usually pieces of the same tool, not rivals. A repository also stays out if the two never met in a discussion.
Privacy and security enhanced releases of Chromium for GrapheneOS. Vanadium provides the WebView and standard user-facing browser on GrapheneOS. It depends on hardening in other GrapheneOS repositories and doesn't include patches not relevant to the build targets used on GrapheneOS.
