Enterprise teams are heavily investing in generative AI, but often struggle with monitoring their models' real-world behavior, risking issues such as data leaks and trust erosion. Observability platforms like Galileo and Langfuse offer solutions, with Galileo emphasizing agent reliability and real-time intervention using deep analytics, while Langfuse provides an open-source framework focused on tracing and cost transparency. Galileo is suited for enterprises needing robust runtime protection, offering advanced metrics and compliance-ready solutions with real-time guardrails. In contrast, Langfuse caters to teams seeking flexible, open-source solutions where they manage their own infrastructure and evaluations. It excels in post-hoc analysis and detailed tracing, ideal for those comfortable with self-hosting and manual interventions. The choice between these platforms depends on whether a team prioritizes comprehensive protection and intervention or prefers flexibility and visibility with minimal upfront costs.
