Switching from FingerprintJS
Replace the library, create a TraceTail client with your API key, and keep sending visitorId to your backend. The two libraries compute different IDs, so each returning visitor gets a new ID once.
import FingerprintJS from '@fingerprintjs/fingerprintjs';
const fp = await FingerprintJS.load();
const { visitorId } = await fp.get();import { TraceTail } from '@tracetail/js';
const tracetail = new TraceTail({ apiKey: 'YOUR_API_KEY', endpoint: 'https://tracetail.io/api' });
const { visitorId } = await tracetail.generateFingerprint();Start identifying visitors today
1,000 requests free every month, no credit card required. Add a card only when you need more.
