Review Langfuse?
Reviewers mostly see Langfuse as a practical observability tool that helps teams trace LLM calls, debug failures faster, monitor usage, costs, latency, and hallucinations, and version prompts without much setup. Users often praise easy integration, helpful SDKs, strong support, and the self-hosted option for regulated environments. Founders of products like Magic Patterns and Agentplace.io say it is core to tracing and improving agent quality. The main caution: complex, long-running agent traces can become hard to parse, and one reviewer notes some roadmap uncertainty.
