Langtrace

Langtrace is an Open Source Observability and Evaluations Platform built specifically for AI agents and LLM-powered applications. If you've ever shipped an AI prototype only to find it behaves unpredictably in production, Langtrace is the tool that bridges that gap. It provides the monitoring, performance measurement, and iterative improvement tools needed to transform experimental AI projects into reliable, enterprise-grade products. Langtrace supports popular frameworks like CrewAI, DSPy, LlamaIndex, and LangChain out of the box, along with a wide range of LLM providers and VectorDBs. Features include simple setup, vital metrics tracking, API request exploration, and prompt version control — everything you need to ship AI that actually works.
