Built-in Web Dashboard

LongTracer comes with a built-in, lightweight web dashboard for viewing your RAG verification traces, checking metrics, and browsing hallucination statistics.

Starting the Dashboard

You can start the dashboard server from your terminal using the CLI:

longtracer serve

By default, the dashboard runs on http://localhost:8000. Open this URL in your web browser to view your traces.

Features

  • Trace Listing: View all verified RAG queries, their sources, and the resulting trust scores.
  • Aggregated Metrics: See your project's overall health, including total traces, average trust score, and total hallucinations.
  • Pagination & Filtering: Easily page through your trace history.

Security

If you deploy the dashboard to a server, you should protect it. The built-in server supports API key authentication for both the REST endpoints and the web dashboard.

Set an API key using the environment variable:

export LONGTRACER_API_KEY="your-super-secret-key"
longtracer serve

When you visit /dashboard, you will be prompted to enter your API key to authenticate. Authentication relies on secure HTTP-only cookies and timing-safe digest comparisons.
