Find C engineers and maintainers

The list above ranks the most-starred public C repositories, drawn from the public GitHub graph. Across 18,150 C repositories in the public graph, the maintainers, top contributors, and recurring committers are a powerful signal for where C expertise lives.

Behind every popular Cproject is a small group of people who actually shipped it. They’re the Cengineers, library authors, and infrastructure builders worth knowing - whether you’re hiring, partnering, or doing technical research.

Refolk turns this list into a search. Ask for “C maintainers hiring”, “contributors to C repos based in Europe”, or “companies whose engineers ship C” and Refolk returns a ranked shortlist with the commits, repos, and profiles that earned each person a spot.

How this list is built

Refolk searched GitHub for public repositories whose primary language is C, ranked them by stargazer count, and kept those with at least 100 stars. The list refreshes once a day.
