Best AI Agent Evaluation Tools in 2026

In short: Noveum is ranked #1 of 29 as of 4 October 2026, ahead of W&B Weave and Opik. The best-ranked option with a free plan is W&B Weave. The lowest first paid tier on this page is Amazon Bedrock Data Automation at $0.01/mo.

When you need to check how an AI agent behaves across tasks, the evaluation approach matters as much as the traces it produces. Compare evaluation methods, safety evaluations and tool-call checks, then look at regression runs, trace ingestion and SDK language support. Dataset limits and free plans can shape how you begin, while paid-from pricing helps frame ongoing costs. Noveum, DeepEval and Future AGI AI Evaluation SDK are among the first entries, alongside Opik and W&B Weave. Use the listed criteria to judge which tools cover the checks and workflow details that matter for your agents.

29 AI agent evaluation tools ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
