Ragas vs. Galileo

Ragas serves as a comprehensive framework that is open-source and focuses on testing and evaluating applications leveraging Large Language Models (LLMs). This framework features automated metrics that assess performance and resilience, in addition to the ability to create synthetic test data tailored to specific requirements, thereby ensuring quality throughout both the development and production stages. Moreover, Ragas is crafted for seamless integration with existing technology ecosystems, providing crucial insights that amplify the effectiveness of LLM applications. The initiative is propelled by a committed team that merges cutting-edge research with hands-on engineering techniques, empowering innovators to reshape the LLM application landscape. Users benefit from the ability to generate high-quality, diverse evaluation datasets customized to their unique needs, which facilitates a thorough assessment of their LLM applications in real-world situations. This methodology not only promotes quality assurance but also encourages the ongoing enhancement of applications through valuable feedback and automated performance metrics, highlighting the models' robustness and efficiency. Additionally, Ragas serves as an essential tool for developers who aspire to take their LLM projects to the next level of sophistication and success. By providing a structured approach to testing and evaluation, Ragas ultimately fosters a thriving environment for innovation in the realm of language models.

Galileo is an AI observability and eval engineering platform built to help organizations measure, protect, and improve AI applications and agents across the full development lifecycle. Now part of Cisco, Galileo is positioned around the idea that teams should not only monitor AI failures, but prevent them with production-ready guardrails. The platform helps teams capture ground truth from synthetic data, development workflows, live production traffic, and subject matter expert annotations. Galileo provides more than 20 out-of-the-box evaluations for RAG systems, agents, safety, security, and custom use cases. Its eval engineering workflow helps teams create accurate evaluators that reflect their own domain expertise instead of relying only on generic metrics. Galileo can auto-tune metrics from live feedback so evaluations become better aligned with real environments. The platform’s Luna models distill expensive LLM-as-judge evaluators into compact models that can run across production traffic at lower cost and lower latency. Galileo’s insights engine analyzes millions of signals across models, prompts, functions, context, datasets, traces, and MCP server activity to identify failure modes and recommend fixes. Teams can use these insights to debug agent behavior, improve prompts, adjust tools, detect hallucinations, and strengthen AI reliability. Galileo supports the eval-to-guardrail lifecycle, where pre-production tests become production policies that can block harmful responses, control tool access, and guide escalation paths. By combining AI observability, evals, ground-truth datasets, Luna guardrail models, agent reliability workflows, safety controls, deployment flexibility, and production monitoring, Galileo helps enterprises ship AI systems with more confidence.
