## At a glance

- **Tool**: Laminar
- **Company**: Laminar (YC S24)
- **Category**: [Developer Productivity & Workflow](https://ai.dosa.dev/category/productivity)
- **Pricing model**: Freemium
- **Official website**: https://laminar.sh

## Key features

- OpenTelemetry-native tracing that auto-instruments Vercel AI SDK, LangChain, Browser Use, OpenAI, Anthropic and Gemini
- Signals that describe agent behaviors in plain English and alert in Slack
- RL-trained flow-1 model for finding errors in agent traces
- Evals SDK and CLI for local runs or CI/CD pipelines
- SQL-backed custom dashboards, data annotation and datasets
- MCP server and CLI so coding agents can query traces

## Pricing

**Model**: Freemium

The platform is open source under Apache-2.0 and can be self-hosted with Docker Compose. The managed cloud has a Free tier, Starter at $30/month, Pro at $150/month and custom Enterprise pricing, with usage-based data overages.

## Who it is for

- **Best for**: Teams building production AI agents who need tracing, failure detection and evals in one open-source platform.
- **Not ideal for**: Individual developers who only want usage stats for their own coding-agent sessions rather than instrumenting an agent application.

## Verdict

A capable, high-performance agent observability stack with a distinctive automated failure-detection model and a self-hosting option.

## Recent updates

Released v0.3.2 on October 16, 2026, and launched on Hacker News on October 19, 2026 with flow-1, an RL-trained model for detecting errors in agent traces.
