Review Langfuse?

Reviewers mostly see Langfuse as a reliable, easy-to-adopt observability tool for LLM apps, especially for tracing, prompt versioning, debugging odd model behavior, and tracking usage, latency, cost, and hallucinations. Several say it integrates smoothly into existing workflows and helps teams fix issues faster or build cheaper, more stable systems. Founders of Magic Patterns and Agentplace say it is core to tracing and improving agent quality. The main caution is that very long, complex agent traces can become hard to parse, with some roadmap uncertainty noted.
