issue-rag alternatives

zaxiu88888/issue-rag (139 stars, +139 this week): RAG over GitHub issues, with a hand-reviewed eval set and an audit of the judge itself. Reports the interval, not just the best number.

Below are 9 other RAG / vector repos tracked by OSS Radar that share at least two GitHub topics about what they do with issue-rag (platform, language and framework tags don't count), ordered by how closely their topics overlap (rarer shared topics count more), then by stars gained in the last 7 days. Topic overlap means a similar problem space, not a drop-in replacement, so check each project's README.
