Open-source observability and analytics for complex LLM apps. From full instrumentation to event-driven analytics and evaluations, Laminar is the only platform you need to debug and understand your complex LLM app. Everything you need to understand and optimize your complex LLM app.

Full Tracing: Track and understand every step of execution in your LLM app by simply adding a few lines of code. Track and understand every step of execution in your LLM app by simply adding a few lines of code. Semantic events: Have a clear understanding of how your LLM app is being used by tracking semantic events. Define events, such as user sentiment, in plain English. We will catch them in the background and turn them into metrics. Evaluations: Run custom evaluations at scale. Build custom evaluation pipelines, including LLM evaluations, and run them on custom datasets. Powered by Rust: Rust allowed us to deliver unparalleled performance and reliability. Laminar can sustain high-throughput and effortlessly scale to processing of millions of tokens per second. Prompt chain management: Laminar lets you go beyond a single prompt. You can build and host complex chains, including mixtures of agents or self-relfecting LLM pipelines.
