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.

One key for 4,100+ agent tools, pay per call
A single treg token routes to 4,100+ endpoints across 127 providers, so no per-provider signups or scattered key files.
See each provider's price plus measured success rate, speed, and last-answer time, and pin a preferred vendor when you want.
Pay fractions of a cent per call with the price shown before you commit, no monthly seats required.
Route calls through your existing provider keys at no markup; credentials are injected server-side and never stored on a machine.
