What is Laminar (LMNR)?

Open-source observability platform for AI agents and LLM applications with tracing, evaluation, and dataset management.

Laminar (lmnr) is an open-source observability platform purpose-built for AI agents and LLM applications. It provides comprehensive tracing, evaluation, and analytics capabilities that help developers understand, debug, and improve their agent systems in development and production.

The platform captures detailed traces of every agent execution — including LLM calls, tool invocations, retrieval operations, and custom spans — with automatic instrumentation for popular frameworks like LangChain, LlamaIndex, CrewAI, and OpenAI. Each trace includes input/output data, token counts, latency measurements, and cost calculations, giving developers full visibility into what their agents are doing and how much it costs.
