Our review
Pros	Traces activity from application and session through agents, traces, and spans Diagnoses retrieval, generation, tool calls, and agent handoffs Evaluates outputs and applies real-time safety guardrails	Trains glassbox Explainable Boosting Machine models. Provides global, local and group feature-importance explanations. What-if analysis and interactive views help inspect model behavior.
Cons	Its emphasis is LLM and agent workflows, not general model explanations Developer pricing scales per trace rather than using a fixed listed fee Support channels listed are limited to documentation	Python toolkit that runs in your own environment, not a hosted service. scikit-learn is the only listed integration. No generated audit reports are confirmed.
