Review Langfuse?
Reviewers see Langfuse as a dependable observability layer for LLM apps, especially for tracing, debugging, prompt versioning, and monitoring costs, latency, token use, hallucinations, and request history. Users repeatedly praise the easy setup, helpful SDKs and integrations, strong support, and the option to self-host when data must stay in-house. Founders of Magic Patterns and Agentplace say it is central to tracing and improving agent quality. The main caveat: very long, tool-heavy agent traces can become hard to parse.
