Find C++ engineers and maintainers

The list above ranks the most-starred public C++ repositories, drawn from the public GitHub graph. Across 25,005 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 C++project is a small group of people who actually shipped it. They’re the C++engineers, 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.
