Hue

Testing for agents built on real usage: it traces real requests, model calls and tool activity, suggests tasks worth replaying, reruns each task in a stateful environment with simulated APIs and MCPs that match production, and scores every rerun so a team can compare agent versions before shipping.

Hue Developer tool

Agent testing platform: traces real requests, model calls and tool activity, suggests tasks worth replaying from real usage and coverage gaps, reruns each task in its own stateful environment with simulated APIs and MCPs that match the real ones, and scores each rerun to compare agent versions; an SDK, or OTLP traces from any OpenTelemetry tool; sold by contact with no published price.
