Our review
Pros
  • Deep agent testing covers trajectories, components, and tool-call correctness.
  • Open-source and free, with Python and TypeScript SDKs.
  • Supports safety metrics, synthetic datasets, tracing, and regression runs.
  • Combines LLM judges with configurable and code-based scorers
  • Evaluates traces, tool calls, safety issues, and human feedback
  • Supports regression tests and CI/CD workflows
Cons
  • The core product is self-hosted rather than a managed service.
  • Shared reports and monitoring require the separate Confident AI platform.
  • Its developer-focused workflow may not suit teams seeking a nontechnical evaluator.
  • Verified SDK coverage is Python
  • The built-in Safety judge is limited to Databricks managed MLflow
  • Support is centered on community resources and documentation
