Sublyzer captures errors, performance, sessions, and security signals from your app. You need a 24-character integration code from the dashboard, then one of the install paths below.

You need your 24-character integration code from the dashboard (Integrations → your app). No secret API keys in the browser — just that code.

The SDK is not on npm. Install via the Windows wizard, a script tag, or download from the SDK Customizer.

Manual — script tag (CDN)

<script
  src="https://www.sublyzer.com/sublyzer.js"
  data-integration-code="YOUR_24_CHAR_CODE"
  defer
></script>

Local dev: add data-api-url="http://localhost:3001"

Manual — download + self-host (Next.js / React)

1. Open SDK Customizer → paste code → Download (sublyzer.js + sublyzer.config.js)
2. Save to public/sdks/sublyzer.js
3. Add the script tag in your layout or HTML:

<script
  src="/sdks/sublyzer.js"
  data-integration-code="YOUR_24_CHAR_CODE"
  defer
></script>

Installer — what it does

The .exe downloads the same canonical sublyzer.js and writes it into your project (e.g. public/sdks/sublyzer.js) plus config snippets for your framework. Same files as the Customizer download.

If you downloaded sublyzer.js from the Customizer or installer, place it under public/sdks/sublyzer.js (Next.js) or your static assets folder:

<script
  src="/sdks/sublyzer.js"
  data-integration-code="YOUR_24_CHAR_CODE"
  defer
></script>

Or load from production CDN: https://www.sublyzer.com/sublyzer.js

After install:

• Open your site and trigger a few page views
• Check the integration dashboard — events appear within seconds
• Use Sublyzer.flush() on page hide if you batch heavily

• Never put API secrets in browser SDKs — only the public integration code.
• Avoid PII in custom events; use opaque user IDs with identify().
• For server apps, prefer generated Node/Python/PHP SDKs from the Customizer or installer.
