Open Source Alternatives to Arize AI

An AI engineering platform for the observability, evaluation, and improvement of AI agents. The software provides tools to trace agent trajectories, run span and session evaluations at scale, and debug issues using an AI engineering agent named Alyx. It is designed for AI engineers to monitor production performance, test prompts, and manage agent trajectories through a datastore called adb. The platform integrates with various models and frameworks including OpenAI, Anthropic, LangChain, and LlamaIndex. It is available as a managed SaaS service or through a local open source version called Phoenix. Users can utilize the platform to turn production signals into better agents by identifying failure modes and iterating on prompts and workflows. The system is built on OpenInference and OpenTelemetry standards to ensure interoperability across different cloud environments.
