You can choose to get started with Decipher by using the HTML script tag or via a package manager below.

Log in to Decipher with your work email. You will receive a snippet to paste into your HTML head, which will look something like the example below:

Initialization (copy and paste)
<script
  src="https://browser.sentry-cdn.com/8.47.0/bundle.tracing.replay.min.js"
  integrity="sha384-VaqNrma84jlgEWxBCMOnatKAHLSjaKGmo8Biuj3NQEg1MrmeukY8s6pnaTgRVjKM"
  crossorigin="anonymous"
></script>
<script>
  Sentry.init({
    dsn: "YOUR_DSN_FROM_DECIPHER", // This will be set for you once you're logged in.
    integrations: [
        Sentry.replayIntegration({
            maskAllText: false,
            blockAllMedia: false,
            maskAllInputs: true
        }),
        // You can optionally specify log levels (see further docs)
        Sentry.captureConsoleIntegration(),
        Sentry.browserTracingIntegration(),
    ],
    replaysOnErrorSampleRate: 1.0,
    replaysSessionSampleRate: 1.0,
  });
</script>

This should be pasted into your website’s HTML head as early as possible. You can configure some of the parameters (e.g. to adjust capture rate).

Identify Users

Identify users where user information is available in your application frontend, typically after authentication or login.

For Next.js applications, ensure that this code is placed in a file that includes the "use client" directive at the top.

// Set user information in Decipher via the Sentry TypeScript SDK
Sentry.setUser({
  "email": "jane.doe@example.com",  // Recommended identifier to set
  "id": "your_internal_unique_identifier", // Optional: use if email not available
  "username": "unique_username", // Optional: use if email not available
  "account": "AcmeCo",  // Recommended: Which account/organization is this user a member of?
  "created_at": "2025-04-01T15:30:00Z", // Recommended: date this user signed up.
  "role": "client", // Optional: what is this user's role/type?
  // You can add more user information here as key/value pairs.
});

Once you’re done, simply use your website to validate that Decipher is collecting session replay data.

Log in to Decipher with your work email. You will receive a snippet to paste into your HTML head, which will look something like the example below:

            maskAllInputs: true
        }),
        // You can optionally specify log levels (see further docs)

Install the SDK

Using your package manager of choice, install the @sentry/browser SDK. This is the only package you need, no matter what framework and libraries your frontend is using.

npm install @sentry/browser --save

Log in to Decipher with your work email. You will receive a snippet to initialize the SDK — paste this at the root of your project frontend/client code. It will look something like this:

Sentry.init({
  dsn: "YOUR_DSN_FROM_DECIPHER", // This will be set for you once you're logged in.
  integrations: [
      Sentry.replayIntegration({
          maskAllText: false,
          blockAllMedia: false,
          maskAllInputs: true
      }),
      // You can optionally specify log levels (see further docs)
      Sentry.captureConsoleIntegration(),
      Sentry.browserTracingIntegration(),
  ],
  replaysOnErrorSampleRate: 1.0,
  replaysSessionSampleRate: 1.0,
  tracesSampleRate: 1.0,
});

You can configure some of the parameters (e.g. to adjust capture rate).
