The first analytics that joins pageviews, page-load time, click heatmap, JavaScript errors and Web Vitals on the same visitor record — so marketing and engineering finally look at the same screen.
Dogfooded on this very site. The numbers below come from the real clycyo.com tracker.
Dev tab · live on every visitor record. Hover to pause.
One <script> tag in your <head>. SPA route changes, page-load time, click events, Web Vitals and JS errors are captured automatically.
On signup, call window.webanalytics.identify(email). Every anonymous event from before the signup merges into one journey.
Call track('subscription_paid', { revenue, plan }) from your Stripe / Polar webhook. Acquisition is already attached.

GET https://clycyo.com/api/public/demoIdentify a user when they sign up. The anonymous pageviews from before the signup stay attached.
Track revenue when they upgrade. The first-touch UTM, referrer, country, device, and even the page-load time of the very first visit are still on the same record.
No new platform when you scale. No re-instrumentation. No vendor migration.
// 1. Identify on signup
window.webanalytics.identify(user.email, {
name: user.name,
source: 'newsletter',
provider: 'beehiiv',
});
// 2. Track meaningful product events
window.webanalytics.track('feature_activated', {
feature: 'team_invites',
count: 3,
});
// 3. Track revenue from your Stripe webhook
window.webanalytics.track('subscription_paid', {
revenue: 29,
currency: 'USD',
plan: 'Pro',
order_id: invoice.id,
});Every metric below comes from the same Postgres that powers the live dashboard. No mock layer, no sampling, no extra setup.
Pair every revenue event with the first-touch UTM source, medium, and campaign captured on the visitor's very first pageview. Export the join, hand it to the CFO.

| Organic search | € 2,310 | 7 paying |
| Direct | € 1,160 | 4 paying |
| Hacker News | € 590 | 2 paying |
Tagged links plus identify(email, { source }) means every confirmed subscriber lands on the same visitor record. Filter by campaign UTM. Watch deliverability translate into pipeline.

The tracker captures navigationStart → loadEventEnd on every initial pageview, and SPA frame-time on every route change. The journey timeline shows it next to every visit, so you can see exactly when a slow page cost you a conversion.
