Trace Inspection
Traces are compressed and analyzed by our internal agent before you read a single message. Get a summary of the full agent journey, key decisions, and issues up front.
Experiments
Compare variants side by side across prompts, harnesses, or config changes.
Surface Problematic Traces
Automatically surface runs that deviate from normal patterns without reviewing every trace.
Variant Metrics
We're heavily optimized to support custom metrics for coding agents. Track tool errors, retries, subagent spins, files read, coverage, behavior patterns, and more across every variant you ship.
Behavior Detection
Define behaviors in plain language and let our agent autonomously find traces with these behaviors.
Production Monitoring
Ingest production traces in real time and catch regressions before your users do.
