About Laminar
Laminar is an open source observability platform for AI agents. It traces LLM applications, runs evaluations, labels production data and feeds results back into prompt improvements. It connects to Vercel AI SDK, LangChain, OpenAI and Anthropic with one line of code, uses OpenTelemetry-native SDKs and is written in Rust. Traces can be queried with SQL, and evaluations plug into CI/CD. A free tier is available.
