Review Langfuse?

Reviewers describe Langfuse as a dependable observability layer for LLM apps, especially valued for tracing, debugging, monitoring token use, hallucinations, costs, latency, and request history. Users repeatedly say it is easy to integrate, works smoothly with SDKs and common workflows, and helps them find edge cases faster and build more stable systems. Several also praise the responsive team. Founders of Magic Patterns and Agentplace say it is core to their agent quality and observability in production.
