Phoenix is an open-source AI observability platform designed for experimentation, evaluation, and troubleshooting. It provides: - [**_Tracing_**](https://arize.com/docs/phoenix/tracing/llm-traces) - Trace your LLM application's runtime using OpenTelemetry-based instrumentation. - [**_Evaluation_**](https://arize.com/docs/phoenix/evaluation/llm-evals) - Leverage LLMs to benchmark your application's performance using response and retrieval evals. - [**_Datasets_**](https://arize.com/docs/phoenix/datasets-and-experiments/overview-datasets) - Create versioned datasets of examples for experimentation, evaluation, and fine-tuning. - [**_Experiments_**](https://arize.com/docs/phoenix/datasets-and-experiments/overview-datasets#experiments) - Track and evaluate changes to prompts, LLMs, and retrieval. - [**_Playground_**](https://arize.com/docs/phoenix/prompt-engineering/overview-prompts)- Optimize prompts, compare models, adjust parameters, and replay traced LLM calls. - [**_Prompt Management_**](https://arize.com/docs/phoenix/prompt-engineering/overview-prompts/prompt-management)- Manage and test prompt changes systematically using version control, tagging, and experimentation. - [**_PXI (Phoenix Intelligence)_**](https://arize.com/docs/phoenix/pxi) - An AI engineering agent built into Phoenix for debugging traces, iterating on prompts, and navigating the product.

Phoenix is vendor and language agnostic with out-of-the-box support for popular frameworks ([OpenAI Agents SDK](https://arize.com/docs/phoenix/tracing/integrations-tracing/openai-agents-sdk), [Claude Agent SDK](https://arize.com/docs/phoenix/integrations/python/claude-agent-sdk), [LangGraph](https://arize.com/docs/phoenix/tracing/integrations-tracing/langchain), [Vercel AI SDK](https://arize.com/docs/phoenix/tracing/integrations-tracing/vercel-ai-sdk), [Mastra](https://arize.com/docs/phoenix/integrations/typescript/mastra), [CrewAI](https://arize.com/docs/phoenix/tracing/integrations-tracing/crewai), [LlamaIndex](https://arize.com/docs/phoenix/tracing/integrations-tracing/llamaindex), [DSPy](https://arize.com/docs/phoenix/tracing/integrations-tracing/dspy)) and LLM providers ([OpenAI](https://arize.com/docs/phoenix/tracing/integrations-tracing/openai), [Anthropic](https://arize.com/docs/phoenix/tracing/integrations-tracing/anthropic), [Google GenAI](https://arize.com/docs/phoenix/tracing/integrations-tracing/google-genai), [Google ADK](https://arize.com/docs/phoenix/integrations/llm-providers/google-gen-ai/google-adk-tracing), [AWS Bedrock](https://arize.com/docs/phoenix/tracing/integrations-tracing/bedrock), [OpenRouter](https://arize.com/docs/phoenix/integrations/python/openrouter), [LiteLLM](https://arize.com/docs/phoenix/tracing/integrations-tracing/litellm), and more). For details on auto-instrumentation, check out the [OpenInference](https://github.com/Arize-ai/openinference) project. Phoenix runs practically anywhere, including your local machine, a Jupyter notebook, a containerized deployment, or in the cloud. ## Run Locally Install Phoenix via `pip` or `conda` and have a fully functional Phoenix ```shell pip install arize-phoenix phoenix serve ``` ## Deploy Phoenix container images are available via [Docker Hub](https://hub.docker.com/r/arizephoenix/phoenix) and can be deployed using Docker or Kubernetes. Arize AI also provides cloud instances at [app.phoenix.arize.com](https://app.phoenix.arize.com/). For Docker Compose, Kubernetes/Helm, and other deployment options, see the [self-hosting documentation](https://arize.com/docs/phoenix/self-hosting).

       

> [!NOTE] > The Google Cloud button builds Phoenix from source in Cloud Shell rather than deploying the prebuilt Docker Hub image. The Azure template serves plain HTTP (Azure Container Instances does not terminate TLS) — front it with a TLS proxy such as an Application Gateway before production use. ## Packages The `arize-phoenix` package includes the entire Phoenix platform. However, if you have deployed the Phoenix platform, there are lightweight Python sub-packages and TypeScript packages that can be used in conjunction with the platform. ### Python Subpackages | Package | Version & Docs | Description | | --------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------ | | [arize-phoenix-otel](https://github.com/Arize-ai/phoenix/tree/main/packages/phoenix-otel) | [](https://pypi.org/project/arize-phoenix-otel/) [](https://arize-phoenix.readthedocs.io/projects/otel/en/latest/index.html) | Provides a lightweight wrapper around OpenTelemetry primitives with Phoenix-aware defaults | | [arize-phoenix-client](https://github.com/Arize-ai/phoenix/tree/main/packages/phoenix-client) | [](https://pypi.org/project/arize-phoenix-client/) [](https://arize-phoenix.readthedocs.io/projects/client/en/latest/index.html) | Lightweight client for interacting with the Phoenix server via its OpenAPI REST interface | | [arize-phoenix-evals](https://github.com/Arize-ai/phoenix/tree/main/packages/phoenix-evals) | [](https://pypi.org/project/arize-phoenix-evals/) [](https://arize-phoenix.readthedocs.io/projects/evals/en/latest/index.html) | Tooling to evaluate LLM applications including RAG relevance, answer relevance, and more | ### TypeScript Subpackages | Package | Version & Docs | Description | | --------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------ | | [@arizeai/phoenix-otel](https://github.com/Arize-ai/phoenix/tree/main/js/packages/phoenix-otel) | [](https://www.npmjs.com/package/@arizeai/phoenix-otel) [](https://arize-ai.github.io/phoenix/) | Provides a lightweight wrapper around OpenTelemetry primitives with Phoenix-aware defaults | | [@arizeai/phoenix-client](https://github.com/Arize-ai/phoenix/tree/main/js/packages/phoenix-client) | [](https://www.npmjs.com/package/@arizeai/phoenix-client) [](https://arize-ai.github.io/phoenix/) | Client for the Arize Phoenix API | | [@arizeai/phoenix-evals](https://github.com/Arize-ai/phoenix/tree/main/js/packages/phoenix-evals) | [](https://www.npmjs.com/package/@arizeai/phoenix-evals) [](https://arize-ai.github.io/phoenix/) | TypeScript evaluation library for LLM applications (alpha release) | | [@arizeai/phoenix-mcp](https://github.com/Arize-ai/phoenix/tree/main/js/packages/phoenix-mcp) | [](https://www.npmjs.com/package/@arizeai/phoenix-mcp) [](./js/packages/phoenix-mcp/README.md) | MCP server implementation for Arize Phoenix providing unified interface to Phoenix's capabilities | | [@arizeai/phoenix-cli](https://github.com/Arize-ai/phoenix/tree/main/js/packages/phoenix-cli) | [](https://www.npmjs.com/package/@arizeai/phoenix-cli) [](https://arize.com/docs/phoenix/sdk-api-reference/typescript/arizeai-phoenix-cli) | CLI for fetching traces, datasets, and experiments for use with Claude Code, Cursor, and other coding agents | ## Tracing Integrations Phoenix is built on top of OpenTelemetry and is vendor, language, and framework agnostic.
