Find engineers shipping RAG

The list above ranks the most-starred public repositories tagged with the RAG topic, drawn from the public GitHub graph. Across 1,530 repositories tagged this way, the maintainers and top contributors are a tight cluster of the people actually building RAG.

Looking for engineers who’ve worked on RAG for real, not just listed it on LinkedIn? The fastest path is the contributor list of these repos. Their commits, issues, and READMEs are public proof of depth.

Refolk turns this list into a search. Ask for “maintainers of top RAG repos who are hiring”, “RAG engineers in San Francisco”, or “founders shipping RAG” and Refolk returns a ranked shortlist with sources.

How this list is built

Refolk searched GitHub for public repositories tagged with the RAG topic, ranked them by stargazer count, and kept those with at least 50 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: Sun, 20 Sep 2026 20:23:41 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.

01Describe them
One plain sentence. Role, city, stack, stage, whatever matters to you.
02I read the web live
GitHub, public LinkedIn and Crunchbase records, the open web. Not a database that went stale last quarter.
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.
