Retrieval-Augmented Generation NLP Tools

Tools and frameworks implementing RAG systems that combine document retrieval with LLM-based generation for knowledge-base question answering, semantic search, and context-aware responses. Does NOT include general information retrieval, semantic search without LLM integration, or knowledge graph construction without retrieval components.

There are 31 retrieval-augmented generation tools tracked. 3 score above 50 (established tier). The highest-rated is web-arena-x/webarena at 55/100 with 1,398 stars.
