About Laminar
Laminar is an open-source LLM observability and evaluation platform that auto-instruments all major LLM SDKs and frameworks with a single initialization line, capturing full traces of LLM calls, tool use, latency, token usage, and cost. It invented browser-agent observability by automatically recording browser sessions and syncing them frame-by-frame with agent traces so developers can see exactly what the agent was seeing during a run. Datasets can be built from span data for evaluations, fine-tuning, and prompt engineering, and the platform is fully self-hostable.
