Find and fix problems in your AI agents before users do
See every message, tool call and decision in a run, with inputs, outputs and durations, so you can pinpoint where a run broke down.
Recurring failures are grouped into issues with severity, affected users, last-seen time and a confidence score, instead of scattered alerts.
An agent investigates issues and automates follow-up across Slack, the web app and MCP, so debugging happens where your team already works.
Run scenarios against a change on a pull request and compare results with real traffic to catch regressions before merge.

The simulation platform for agent self-improvement
Run your agent through thousands of realistic scenarios and get scored feedback in minutes instead of waiting weeks for expert log review.
Create structured experiments and test ideas quickly in an AI laboratory before committing to a change.
Start from a validated metric library of industry benchmarks, customize proven metrics, or build your own to track what matters.
Create, test and track your best-performing prompts in one place, keeping a history and a single source of truth for the team.
