Best alternatives to Laminar in 2026
When an AI agent goes wrong — takes the wrong action, loops forever, calls the wrong tool — figuring out why can mean digging through a mess of raw logs across dozens of steps. Laminar is built to make that debugging visual: it traces every LLM call, tool call and sub-agent your agent runs, whether the task finishes in one turn or hundreds of steps across parallel sub-agents, and lays it out so a developer can see exactly where things went sideways. Laminar is an open-source, OpenTelemetry-native observability platform purpose-built for AI agents (as opposed to general LLM apps), a Y Combinator S24 company with 3,100+ GitHub stars on its Apache 2.0-licensed core. It supports popular agent frameworks out of the box — Vercel AI SDK, Claude Agent SDK, OpenAI Agents SDK, LangGraph, Mastra, Browser Use, Stagehand — and adds features specific to agent debugging like automatic browser-agent tracing with synced window recordings, so you can watch what a browser-automation agent actually saw while it acted. It's Rust-powered on the backend for high trace throughput, and offers both managed Laminar Cloud and full self-hosting. Pricing runs Free (1GB, 7-day retention), Starter at $30/month (3GB, 30-day retention, unlimited seats), Pro at $150/month (10GB, 6-month retention), and custom Enterprise.
