Production model monitoringmedium

↓ Weaknesses

Steep learning curve for non-Python developershigh

API requires Python-specific patterns, TypeScript SDK is community-maintained

Frequent breaking changes between versionsmedium

v0.1 to v0.2 migration required rewriting chain definitions

Limited language support beyond Pythonhigh

Primary SDK is in Python, and secondary languages like TypeScript have limited community support

Expensive at scale for large enterprisesmedium

Pricing model becomes costly with increased experiment tracking and artifact storage needs
