Laminar is an open-source, OpenTelemetry-native observability platform purpose-built for AI agents, offering tracing, plain-language failure detection (Signals), evaluations, datasets, and dashboards. It is written in Rust for high performance, can be self-hosted via Docker Compose, and provides SDKs, a CLI, and an MCP server for querying trace data.
Use cases
- trace llm calls and tool calls in my ai agent
- detect when my agent gets stuck in a loop and alert me in slack
- run llm evals in ci/cd against datasets
- self-host an llm observability platform
- debug agent failures across thousands of traces
- query agent traces with sql from my coding agent
- build evaluation datasets from production traces
When to choose
- you are building or operating LLM agents in production and need tracing, failure detection, and evals in one platform
- you want OpenTelemetry-native tracing with auto-instrumentation for LangChain, Vercel AI SDK, OpenAI, Anthropic, and more
- you need to self-host observability infrastructure with high-performance ingestion and trace compression
When to avoid
- you only need generic application APM without LLM/agent-specific features
- you want a fully managed zero-maintenance solution and cannot run Docker services
- your project is not LLM/agent-based and would not benefit from trace analysis of agent runs
