Review Langfuse?
Reviewers mostly see Langfuse as a dependable observability tool that makes LLM apps easier to trace, debug, and improve. Users repeatedly praise detailed tracing, prompt versioning, easy integration, useful analytics around cost, latency, tokens, and hallucinations, plus the self-hosted option for sensitive environments. Several also say the team is responsive and the product “just works.” Founders of Magic Patterns and Agentplace likewise credit it for tracing model calls and improving agent quality. The main caveat: very long, complex agent traces can become hard to parse.
