Laminar — Technical Overview
Laminar is an open-source observability platform (Apache 2.0) purpose-built for AI agents. It provides deep tracing, monitoring, and failure-detection infrastructure for teams building and operating AI agents at scale.
Key technical capabilities:
- Automatic failure detection (Signals): Detects agent failures without requiring pre-defined rules — no manual threshold configuration needed.
- Trace compression: Achieves up to 20× cheaper storage through built-in trace compression, reducing infrastructure costs at scale.
- Full-text search: Query across all span inputs, outputs, and attributes in real time.
- MCP & CLI access: Coding agents can query traces directly using SQL via MCP (Model Context Protocol) and CLI interfaces.
- Browser session recording: Captures full browser sessions for browser-based agents (e.g., Playwright, Stagehand, Browser Use).
- Self-hosting: Deploy on your own infrastructure via Docker, Helm, or Kubernetes.
- API access: Programmatic access to all platform features.
- Compliance: HIPAA & SOC 2 Type II compliant, with built-in PII redaction.
- Alerting: Slack integration for real-time failure alerts and investigation workflows.
Integrations: Claude Agent SDK, OpenAI Agents SDK, Mastra, Pydantic AI, Vercel AI SDK, LangChain, OpenHands SDK, Browser Use, Stagehand, Playwright, Anthropic SDK, OpenAI SDK, LiteLLM, DeepAgents, OpenCode SDK, Gemini API, and Slack.
