Laminar is an open-source observability and evaluation platform purpose-built for AI agent applications. It serves AI engineering teams building agents on top of LLMs and tool-calling stacks. The "rerun at step N with preserved context" debugger lets engineers replay and edit failed agent trajectories where general-purpose LLM observability tools stop at logging.
