Arize Phoenix: Open Source AI Development Platform.
This page is designed to help you find out whether Arize Phoenix is good and if it is the right choice for you.
Arize Phoenix is the open-source AI observability and evaluation platform from Arize AI, built for developers who want to trace, evaluate, troubleshoot, and improve AI applications and agents in their own environment. Phoenix supports tracing, evaluations, datasets, experiments, prompt management, and debugging workflows, and is built on open standards including OpenTelemetry and OpenInference. Within the broader Arize ecosystem, Phoenix gives developers an open-source entry point for building and testing AI systems, while Arize AX extends those same standards and workflows into a managed platform for production-scale observability, online evaluations, monitoring, and continual improvement.

Open source and free to self-host
Phoenix is open source (Elastic License 2.0) and can be run locally, in a notebook, in Docker, or on Kubernetes at no licensing cost. This gives teams full control over their data and avoids vendor lock-in, which is useful for experimentation and privacy-sensitive workloads.
Built on OpenTelemetry and OpenInference
Tracing is based on OpenTelemetry standards and the OpenInference instrumentation conventions. This makes it vendor- and framework-agnostic, with auto-instrumentation for LangChain, LlamaIndex, OpenAI, Anthropic, Bedrock, DSPy and others, and lets traces be exported to other OTel-compatible backends.
Comprehensive LLM observability and evaluation
It combines tracing, LLM-based and code-based evaluations, datasets, experiments, prompt management and a playground in one tool. Teams can inspect spans, debug retrieval and agent workflows, run evals on traces, and compare experiments as they iterate on applications.
Easy local setup and notebook-friendly
Phoenix can be launched with a simple pip install and a few lines of code, running locally or in Jupyter/Colab. This shortens the path from prototype to visibility into how an LLM app behaves, without requiring account creation or heavy infrastructure.
Clear upgrade path to Arize AX
Because Phoenix shares concepts and instrumentation with Arize's commercial AX platform, teams can begin with the free tool and later move to a managed, enterprise-grade offering with more scale, monitoring and support without re-instrumenting their code.
