Testing AI agents can involve reviewing outputs, traces, and how they handle tools or safety-related checks. Compare evaluation methods, safety evaluations, and tool-call checks with trace ingestion and support for the SDK languages you use. Dataset limits and regression runs may shape how you organize repeat evaluations; free plans and paid-from prices add cost considerations. DeepEval, AgentClash, and Future AGI AI Evaluation SDK are among the opening entries, followed by Noveum and MLflow GenAI Evaluation. The products are presented in ranked best-of order, so weigh that ordering with the evaluation coverage and workflow details relevant to your work.
