About

Phoenix is an open-source observability library designed for experimentation, evaluation, and troubleshooting. It allows AI engineers and data scientists to quickly visualize their data, evaluate performance, track down issues, and export data to improve. Phoenix is built by Arize AI, the company behind the industry-leading AI observability platform, and a set of core contributors. Phoenix works with OpenTelemetry and OpenInference instrumentation. The main Phoenix package is arize-phoenix. We offer several helper packages for specific use cases. Our semantic layer is to add LLM telemetry to OpenTelemetry. Automatically instrumenting popular packages. Phoenix's open-source library supports tracing for AI applications, via manual instrumentation or through integrations with LlamaIndex, Langchain, OpenAI, and others. LLM tracing records the paths taken by requests as they propagate through multiple steps or components of an LLM application.

About

telemetry.dev is an OpenTelemetry-native observability platform for AI agents and LLM applications. Developers can trace model calls, tool steps, retrievals, logs, and metrics; inspect failures, latency, token usage, and estimated cost; and compare activity by model, provider, and environment. It supports first-party TypeScript and Python SDKs, provider and framework integrations, and standard OTLP/HTTP ingest. Environment-level capture controls, SDK masking, and server-side redaction help teams manage stored prompt, response, and telemetry content.
