Langfuse describes itself as an open source AI engineering platform for tracing, monitoring, datasets, experiments, and evaluation to help teams build production-grade LLM applications faster. Its integrated platform supports observability (hierarchical traces for LLM calls, tool invocations, and retrieval steps), evaluation (LLM-as-a-judge, heuristic functions, or human review on production data or experiments), and prompt management, along with experiments, human annotation workflows, and cost/latency monitoring with dashboards and alerts. The site states Langfuse works with stacks that support OTel instrumentation and lists native SDK support for Python and TypeScript, along with “100+ integrations,” and references multiple agent frameworks and model providers. Langfuse also states it joined ClickHouse in January 2026.
