Best AI Agent Evaluation Tools 2026
Evaluating AI agents means considering how you’ll assess behavior, catch regressions, and review safety across tasks. Compare evaluation methods, safety evaluations, and tool-call checks, along with trace ingestion and SDK language support for the stack you use. Dataset limits and regression-run capabilities can shape how evaluations fit into ongoing development; free-plan availability and paid-from pricing are useful access points to weigh. Arklex, Future AGI AI Evaluation SDK, and Noveum are among the options shown, with AgentClash, Braintrust, DeepEval, Galileo, and Giskard also represented. Use the listed criteria to focus on the evaluation and trace workflows relevant to your work, and on whether language support and dataset limits meet your needs.
