About
Phoenix provides a comprehensive toolkit for AI engineering, enabling developers to debug LLM application issues through detailed traces, run systematic evaluations on datasets, and monitor production AI systems in real-time. By leveraging OpenTelemetry standards, it offers a vendor-neutral approach to observability, allowing teams to compare prompts and models through experiment pipelines and ensure quality with LLM-as-judge evaluators. It is ideal for teams seeking a self-hosted alternative to managed platforms like LangSmith, providing deep insights into RAG pipelines, agentic workflows, and token usage.
