Measure Every Agent Run
Spot issues faster, iterate quickly, and raise the bar with every release. Understand performance in production across your entire team.
MetricsMonitor agent performance with comprehensive metrics dashboards. Track costs, latencies, and quality scores.
Traces and LogsSee the full story behind every agent run. Capture telemetry automatically and understand what happened and how it all connects.
ScorersScore outputs with LLM-as-Judge or code. Run online evals in production or score any historical trace retroactively.
Datasets and ExperimentsDefine what good looks like, then measure against it. Build regression sets from production traces and run experiments after every change.
Continuously Improve Your Agents
Treat shipping as just the beginning. Learn from real usage, turn insights into action, and improve every release — all in one place.

Iterate FastTest agents in Studio. Switch models, tweak settings, and try different inputs.
Edit and Test PromptsNo code required. See how changes affect outputs immediately, then serve different variants in production.
Agent VersioningSave agent configurations as versions. Compare side by side and roll back when something breaks.
Assign and Test ToolsTest how agents perform with different tools. Browse MCP servers and swap configurations to find the right setup.
MemoryInspect agent memories. See active observations, browse previous reflections, and monitor token usage against context thresholds.
Bring In Your Team
Gather expert feedback on agent performance and iterate on prompts together. Share traces so anyone can understand user behavior, debug issues, or assess response quality.

Start Building, Then Invite Your TeamRun Studio on localhost. When ready, share it behind a URL — your team gets the same workspace.
AuthenticationLock down Studio with role-based access. Define who can view, edit, and execute.
Invite Domain ExpertsBring in sales, support, compliance, QA, or anyone who knows what a good response looks like. Let them review traces, build datasets, run experiments, and refine prompts — no source code access required.
