CortexOps vs Arize Phoenix: AI Agent Observability Compared

Short summary

Arize Phoenix excels at notebook-based RAG development with mature OpenTelemetry support; CortexOps is better for production agents needing CI/CD evaluation gates and multi-framework tracing without span-based pricing limits. Phoenix scales for research; CortexOps scales cost-effectively for high-volume deployments. Both open source—choose based on workflow type and trace volume.

• •Phoenix: best for notebook experimentation, RAG evaluation, embeddings analysis, mature OTel conventions
• •CortexOps: best for production CI/CD gates, multi-framework agents, flat-rate $49/month pricing model
• •Span-based pricing makes Phoenix expensive at scale; CortexOps unlimited traces model favors high-volume workloads
