Langfuse vs. Braintrust
Compare Langfuse vs. Braintrust for Observability. We want you to choose the most suitable tool for your use case, even if it’s not us.
As cloud-native environments continue to grow in complexity, observability has become essential for ensuring the reliability, performance, and scalability of modern applications. From monitoring infrastructure health, enabling deep visibility into distributed systems, or getting real-time insights into reasoning paths, token usage of LLM Agentic applications. However, traditional vendors sliced visibility into separate products (APM, Log Management, Infrastructure Monitoring, LLM Observability) and priced them in ways that forced tradeoffs making it important for team to choosing the right observability platform is critical to operational success.
The right choice depends on your priorities: cost, control, scale, and flexibility. In the following sections, we’ll compare both platforms to help you determine which best fits your needs, even if the answer isn’t us.

Langfuse overview
A popular open-source (MIT) LLM observability project, self-hostable for teams with strict data-residency needs. Strong for engineering-led teams happy to run and scale their own stack; now part of ClickHouse.
Braintrust overview
An independent, eval-first AI development platform that connects logging, evaluation in CI, and human review in one workflow, with a gateway for routing model calls and granular cost analytics. Strong for engineering teams that want production-grade evals tied to their dev loop; it's focused on LLM workloads rather than full-stack infrastructure, and its in-your-cloud (hybrid data-plane) deployment is reserved for the Enterprise tier.
