What you actually get

Built for the
post-cookie world.

First-party domain

Pixel lives on your domain, not a third-party CDN. Survives iOS Intelligent Tracking Prevention, Brave, ad blockers, and ITP-equivalent rules.

Cookieless fingerprinting

Identifies visitors by IP, user agent, screen resolution, and device characteristics. Persistent profiles across sessions without cookies.

Cross-device stitching

Mobile click → desktop demo → email follow-up. Cometly stitches them into one journey, even when the user identifies themselves days later.

Auto-tracks every page

Page views, scroll depth, time on page, form interactions, all captured with no event configuration. Custom events when you need them.

One-line install

Drop a single script tag in your <head>. No GTM-required, no manual event mapping, no client-side JavaScript SDKs to configure.

Form auto capture

The Comet Pixel picks up email, first name, and last name from standard form fields when someone submits. Those fields ride along with the identify event into Cometly so journeys and server-side conversions stay tied to a real person — no extra tags or SDK wiring for each form.

Works with your stack

Replaces a fragile pile of pixels.

Most teams come in running Meta Pixel, Google Tag, GA4, plus a few internal scripts, and losing data at every step. The Comet Pixel replaces all of it with one supported install.

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 <head>. 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.
