txtai alternatives

neuml/txtai (13k stars, +161 this week): All-in-one AI framework for semantic search, LLM orchestration and language model workflows.

Below are 11 other RAG / vector repos tracked by OSS Radar that share at least two GitHub topics about what they do with txtai (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.
