Ragas
Freemium
Open-source framework for testing and evaluating LLM applications
What is Ragas?
Ragas is an open source framework for testing and evaluating LLM applications. It is positioned as a quality layer for teams that want to assess application behavior while building and then keep monitoring quality after deployment.
The homepage highlights three core capabilities: metrics for evaluating performance and robustness, synthetic test data generation for building evaluation sets, and online monitoring for production use. The product is presented as a framework for working on RAG and other LLM application quality checks with a single toolset.
What can Ragas do?
Synthetic evaluation data
Generate synthetic evaluation data that is described as high quality, diverse, and customized to your requirements.
Online monitoring
Monitor application quality in production and use the resulting insights to improve the application over time.
Development-to-production workflow
Support quality workflows across development and production rather than limiting evaluation to a single stage.
Use Cases
“Model and application evaluation”
Create evaluation metrics to understand how an LLM application is performing and where it is fragile.
“Synthetic dataset creation”
Generate synthetic test data to build evaluation sets tailored to a specific application or domain.
“Production quality monitoring”
Monitor deployed applications and review production quality signals to guide improvements.
“End-to-end quality workflows”
Use the same framework across build and deploy stages when quality checks need to stay consistent.
