Laminar
Open-source platform to trace, evaluate, and improve AI agents.

Laminar is an open-source observability platform built specifically for AI agents, enabling developers to trace LLM calls, tool use, and custom functions. It provides agent debugging, browser session replay, signal extraction from traces, SQL-based data querying, and evaluation pipelines. Teams can use it both during development and in production to understand agent behavior and iterate quickly.
Developers integrate Laminar with two lines of code alongside their existing AI frameworks, which then captures traces of every LLM call, tool execution, and function, enabling replay, signal extraction, and evaluation.
