Book a call and we'll review your install plan. Talk to sales → How is this different from the Meta Pixel? Meta Pixel is third-party (lives on Meta's domain) and cookie-based. The Comet Pixel is first-party (lives on yours) and cookieless. iOS, Brave, and ad blockers can't break it the same way. Does it conflict with my Meta or Google pixels? No, runs alongside. Cometly deduplicates events automatically and improves match quality on Meta from typically 4–5 / 10 to 9.3 / 10 without disrupting your existing campaigns. How does fingerprinting handle privacy? Fingerprints are non-identifying by default and become identified only when the user explicitly identifies themselves (form fill, signup, login). We support GDPR, CCPA, and EU consent frameworks. What if I'm using GTM? The Comet Pixel works inside Google Tag Manager, drop the snippet into a custom HTML tag, set the trigger to All Pages, done. Most GTM-based teams install in under five minutes. Can I install on a Webflow / Framer / WordPress site? Yes. One script tag in the . Works on Webflow, Framer, WordPress, custom Next.js apps, Vue apps, anything that lets you add a tag. ## One pixel. Stays alive One cookieless pixel that captures every session, click, and journey your current pixel + GA4 setup is missing — and stays alive across devices, browsers, and iOS updates.
