Retrieval-augmented generation, embeddings, vector stores, and the memory and knowledge layers that ground models in real data.
These are our picks, not a scrape of GitHub trending: every repo here is one we covered in Repository Radar because we thought it worth tracking. Ranked by stars, with live metrics and a get-it block on each.
21 repos in this category. Browse or filter the full archive → · Compare all categories →
21 repos, our 4th-largest category (Agents & Orchestration leads with 92). Combined they're up 115% since we covered them, 4th-fastest-growing of our 9 categories. They hold 653k stars, 2k contributors and 726k weekly downloads between them. Strength runs broad, not top-heavy: the median repo (26k stars) sits close to the 31k average. 10 are breaking out and 19 still actively shipping, and Python leads on language. What's pulling ahead: claude skills and long term memory projects.
