Review Langfuse?
Reviewers mostly see Langfuse as a dependable way to trace, debug, and understand LLM apps, with repeated praise for prompt versioning, analytics on cost and latency, easy integration, and helpful SDKs. Users also value the self-hosted setup for regulated environments and say it helps catch edge cases, hallucinations, and unstable behavior faster. Founders of Magic Patterns and Agentplace.io say it is central to their agent observability. The main caveat: complex, long-running agent traces can become hard to parse, and one reviewer noted roadmap uncertainty after the ClickHouse acquisition.
