RAG Pipeline Optimization Vector Databases

Tools for benchmarking, evaluating, and optimizing RAG pipeline components (chunking, embedding, retrieval methods). Includes frameworks for testing configurations, comparing techniques, and improving retrieval quality. Does NOT include full RAG applications, domain-specific implementations, or vector database backends themselves.

There are 20 rag pipeline optimization tools tracked. 1 score above 50 (established tier). The highest-rated is danny-avila/rag_api at 64/100 with 772 stars. 1 of the top 10 are actively maintained.
