Ragas is one of 20 APIs that [Evals](https://apis.io/providers/evals/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Open-Source, RAG, Faithfulness, Context Recall, and Library. The published artifact set on APIs.io includes API documentation and a GitHub repository.

Ragas is an open-source evaluation library focused on retrieval-augmented generation, described in its own docs as "a library that helps you move from 'vibe checks' to systematic evaluation loops for your AI applications." It exposes LLM-driven metrics for RAG (faithfulness, context recall, answer relevancy), integrates with LangChain and LlamaIndex, and supports custom metric authoring as a complement to other eval platforms (Weave, LangSmith).
