Ragas

Open-source evaluation framework for RAG and LLM applications.

Ragas fits teams building RAG systems who need metrics, test datasets, evaluation pipelines, faithfulness checks, retrieval quality review, and a repeatable way to compare changes before claiming the knowledge base is production-ready.

Qidao take

Ragas is strongest for RAG evaluation. It is a weaker fit for simple content generation.

Qidao fit index: 85/100

This is a Qidao method score for workflow fit, decision clarity, alternatives, risk, and practical use. It is not a user rating, paid placement, or benchmark claim.
