Find C++ engineers and maintainers

The list above ranks the most-starred public C++ repositories, drawn from the public GitHub graph. Across 25,625 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.

Common questions

How are these repositories ranked?

By stars, with forks and recent activity as tiebreakers, read from the public GitHub API. The methodology section above has the details.

How fresh is the data?

The ranking re-renders at least daily. Last refreshed: Mon, 21 Sep 2026 03:31:59 GMT.

Can I find the maintainers and contributors behind these repos?

Yes. Stars rank the projects; I can rank the engineers - maintainers, top contributors, and the people they work with. You start with 500 free credits, no card required.

Can I use this list for hiring?

That's the point. I read hiring signals across GitHub, LinkedIn, and the open web, so a repo list turns into a shortlist of engineers worth talking to.

Try it on the search you came here for

Stop building boolean strings. Just describe the person.

Type one sentence. I plan the search, read GitHub, public LinkedIn and Crunchbase records, and the open web as it is right now, and hand back a ranked list with the reason next to every name.

  1. 01Describe them

    One plain sentence. Role, city, stack, stage, whatever matters to you.

  2. 02I read the web live

    GitHub, public LinkedIn and Crunchbase records, the open web. Not a database that went stale last quarter.

  3. 03You read the shortlist

    Ranked, with the reasoning under every name. Open a profile, ask a follow-up, narrow it down.

  • No boolean, no filters, no seat to buy. One box.
  • Read at search time, so a profile updated yesterday counts today.
  • Every step visible as it runs, every name with its reason.
