Laminar
Open-source AI agent observability platform
Last verified August 15, 2026 · Updated daily
What Laminar is building
AI agents don't fail cleanly. They run for 40 minutes, make 200 decisions, and crash in a way that a tree of spans can't explain. Laminar is the observability layer built for that. With one line of code, it captures every LLM call, tool use, and function execution across a long-running agent session. For browser agents, it syncs screen recordings directly to traces so you can see what the agent was looking at when it made a bad decision. Its 'Signals' feature uses AI to surface failure patterns across sessions automatically, turning raw traces into a feedback loop. The product is open-source and already the default observability tool in Browser Use's documentation and OpenHands' benchmarking infrastructure.
Why this matters
The observability category was built for simple request-response LLM calls. Every major tool in the space, Datadog, LangSmith, Langfuse, was designed for chains that terminate in milliseconds. But the wave that's actually arriving is autonomous agents: pipelines that run for tens of minutes, spawn subagents, interact with browsers, write code, and fail non-deterministically. That's a fundamentally different debugging problem. Laminar is the first company purpose-built for it, and they already have real traction: Gusto, Browser Use, OpenHands, and Alai are live customers. The angel roster is deliberately strategic here. Ben Sigelman is the co-creator of OpenTelemetry, the standard that governs how observability data is generated and exported across the software industry. His bet on Laminar is a signal that agent-native observability is about to become a standards conversation, not just a tooling one.
