Review Langfuse?
Reviewers mostly see Langfuse as a reliable, easy-to-integrate observability tool that helps teams trace LLM calls, debug odd outputs, monitor tokens, latency, cost, and hallucinations, and move faster with prompt versioning and solid SDKs. Users also value self-hosting for regulated environments and praise the team’s responsiveness. A recurring caveat is that very long, tool-heavy agent traces can become hard to parse, making complex agent debugging feel less suited to the current interface. Founders of and echo its importance for production tracing and quality improvement.
