Tools to Evaluate Agents

AgentOps is explicitly built to provide observability, replay debugging, and evaluation for agents: it captures agent events, lets you rewind and replay runs, and generates analytics and cost tracking so you can turn subjective impressions into repeatable signals.

Best for: Teams and developers who want a CI-friendly observability layer, run automated evaluations, and keep an audit trail for agent runs.

Orbit is a harness that wraps agent runs into structured missions with validation gates, rubric-based scoring, checkpoint resumability, and automated retries — exactly the primitives you need to make agent evaluation repeatable and gate changes in CI.

Best for: Engineers who want to enforce tests and lint/typecheck/validation gates around agent tasks and score runs consistently before changes land.

Latitude focuses on tracing agent failures, clustering them, and generating targeted evals from real production failures, which helps convert ad-hoc observations into reproducible tests and regression suites.

Best for: Teams that need to turn real-world production errors into structured evaluations and alerts for ongoing agent quality monitoring.

Agent-QA is an agentic QA harness that lets you write end-to-end tests in natural language and run them across agent-driven flows, building execution memory across runs so tests become more stable and catch regressions.

Best for: Developers who want to express expected agent behaviours as human-readable tests and repeatedly run those end-to-end checks against agent interactions.
