Web UI

A local dashboard at http://127.0.0.1:7391 with status, traces, cost, alerts, budget, and drift views.

tj serve starts a local dashboard at http://127.0.0.1:7391/.

tj serve

The web UI is a single Vite-built bundle served by the local REST API. No external dependencies, no cloud calls.

Views

  • Status: agent overview with cost, tokens, tool calls, and active alerts.
  • Traces: trace list with span waterfall visualization. Click any span to see its full attribute set.
  • Cost: breakdown by agent, model, day, or tool. Stacked and time-series views.
  • Alerts: alert history with severity filtering. Acknowledge alerts inline.
  • Budget: view and edit daily/session cost limits per agent. Changes are written to your config file.
  • Drift: behavioral drift report with Z-score analysis. Compares the latest session against a learned baseline.

Auto-polling

The UI auto-refreshes every few seconds while a session is active. Disable from the settings menu if you’d rather refresh manually.

Sharing

By default tj serve binds to 127.0.0.1 (loopback only). To make the dashboard accessible from another machine on your network:

tj serve --host 0.0.0.0

Authentication can be enabled in Configuration. The ingest secret is separate from UI auth.

No signup, no cloud. Runs entirely on your machine.
