Review Langfuse?

Reviewers mostly see Langfuse as a practical, dependable observability tool for LLM apps, especially for tracing requests, debugging edge cases, tracking token usage, and watching cost, latency, and hallucinations. Users repeatedly praise its easy setup, strong SDKs and integrations, helpful team, and the flexibility of self-hosting for regulated environments. Founders of Magic Patterns and Agentplace say it is core to tracing and improving agent quality. The main caveat: reviewers say complex, long-running agent traces can become hard to parse, and one user notes some roadmap uncertainty.
