Sublyzer provides native SDKs for 11 platforms. Each SDK auto-initializes, captures errors, sends events, and flushes data automatically. Use the tabs below to see documentation for your framework.

Use this split so you know what the SDK already does vs what you wire for product metrics.

Three patterns for SaaS funnels. No marketplace / listing events — keep names stable so Overview and reports stay comparable.

1) Signup completed

// After account creation succeeds
Sublyzer.identify(user.id);
Sublyzer.trackEvent('signup_completed', {
  method: 'email',          // or 'google', 'sso'
  plan: 'free',
  source: 'landing_hero',
});

2) Checkout / purchase

// After payment provider confirms success
Sublyzer.identify(user.id);
Sublyzer.trackEvent('checkout_completed', {
  plan: 'pro',
  amount: 29.99,
  currency: 'EUR',
  interval: 'monthly',
});

3) Trial started

// When the trial clock starts (not when they only open pricing)
Sublyzer.identify(user.id);
Sublyzer.trackEvent('trial_started', {
  plan: 'pro',
  trial_days: 14,
  source: 'pricing_cta',
});

Drop-in script for any website. Captures errors, performance metrics, page views, clicks, form submissions, and device info automatically.

Option A — Installer or SDK Customizer: download sublyzer-installer.exe or generate files at https://www.sublyzer.com/sdk-customizer (JavaScript → Browser).

Option B — Script tag (CDN):

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

Option C — Self-hosted: place downloaded sublyzer.js in your static folder:

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

There is no public npm package yet — use the installer, CDN script tag, or Customizer download above.

// sublyzer.config.js
module.exports = {
  integrationCode: 'YOUR_24_CHAR_CODE',
  apiUrl: 'https://sublyzer-backend-production.up.railway.app',
  debug: false,
};

// Track a custom event
Sublyzer.trackEvent('purchase', { plan: 'pro', amount: 29.99 });

// Track an error manually
Sublyzer.trackError('Payment failed', error.stack);

// Identify a user (links events to a specific user)
Sublyzer.identify('user_12345');

// Force flush queued events
Sublyzer.flush();

• JavaScript errors & unhandled promise rejections
• Web Vitals (LCP, CLS)
• Page load performance (DOM, TTFB, DNS, TCP)
• Page views (including SPA navigation)
• Click tracking (tag, id, class, text, coordinates)
• Form submissions
• Device & browser info

• Auto-initialization — SDK validates the integration code on startup
• Error tracking — Uncaught exceptions and errors are captured automatically
• Event batching — Events queue locally and flush in batches (threshold: 10-20 events)
• Auto-flush — Queued events are sent every 30 seconds automatically
• Graceful shutdown — Events are flushed before the process/app exits
• Session & User IDs — Persistent identifiers for tracking across sessions
• identify() — Link events to a specific user ID
• Retry on failure — Failed flushes re-queue events for the next attempt
