# Welcome to Traceback

> Real-time error monitoring, AI root-cause analysis, and distributed observability for modern applications.

Traceback is a developer-first observability and debugging platform built to capture exceptions, inspect distributed execution paths, and pinpoint the exact line of code responsible for failures in production.

Our automated AI reasoning engine analyzes crash contexts, symbolicated stack traces, and session replays to diagnose regressions in seconds instead of hours.

```

<Steps>
  <Step title="Initialize the SDK">
    Add the lightweight SDK to your application. Setup requires only your project DSN.

    ```bash theme={null}
    npm install @traceback/browser
    ```
  </Step>

  <Step title="Capture Unhandled & Handled Errors">
    Traceback automatically captures unhandled rejections, uncaught exceptions, and custom breadcrumbs.

    ```typescript theme={null}
    import * as Traceback from "@traceback/browser";

    Traceback.init({
      dsn: "https://tb_live_k82019482@ingest.traceback.dev/942",
      environment: "production",
      tracesSampleRate: 1.0,
      replaysSessionSampleRate: 0.1,
      replaysOnErrorSampleRate: 1.0
    });
    ```
  </Step>

  <Step title="Inspect Root Cause in Seconds">
    When an incident occurs, view the symbolicated stack trace, network requests, console logs, and AI root cause summary directly in your [dashboard](https://app.traceback.dev).
  </Step>
</Steps>
