Review Langfuse?

Reviewers mostly see Langfuse as a dependable LLM observability tool that is easy to integrate and strong at tracing, prompt versioning, debugging, and tracking costs, latency, token use, and odd model behavior. Users also praise the helpful team, SDKs, reports, and self-hosting for regulated setups. Founders of Magic Patterns and Agentplace say it is central to tracing and improving agent quality. The main caveat: very long, tool-heavy agent runs can become hard to parse, and one reviewer notes some roadmap uncertainty.
