See what TraceTail sees
The TraceTail script runs in this browser and shows your visitor ID, the time it took and every signal behind it. No sign-up needed.

Signals behind the ID
Exactly what the SDK collected in this browser.
The code on this page
This page loads the same script you add to your site, with a demo key that only works on tracetail.io. Its requests go through the real API but are not stored or counted.
<script src="https://tracetail.io/sdk.js" data-api-key="YOUR_API_KEY"></script>
<script>
TraceTail.generateFingerprint().then(({ visitorId }) => {
// Send visitorId to your backend with the request you want to recognize.
});
</script>The button calls TraceTail.generateFingerprint({ verbose: true, refresh: true }): verbose adds the signals to the result, and refresh skips the cache so each run is measured again.
Without a key
The script computes the same visitor ID in the browser and sends nothing. Use it to try TraceTail on any page; nothing shows in a dashboard.
With your key
Each identification is also registered with the API: it counts toward your usage, shows in your dashboard and returns a request ID and a bot check. Keys only work on the domains you register.
