Full integration with GTM and GA4. Auto-fires compliance signals directly to prevent analytical dark spots.
Honor mandatory GPC requirements in the 12 states that require them. Automatically detect browser privacy configurations.
Async and non-blocking by design. Loaded through high-performance workers to preserve core Web Vitals and SEO rankings.
See exact consent ratios, opt-out counts, GPC broadcast signals, and visitor distributions within your panel.
Inject your brand colors, custom font profiles, and toggle positions cleanly. White-label supports full custom CSS overrides.

No complicated code paths. Just copy our single optimized tag, paste it at the top of your site's header, and ConsentKit can render the right UI for its supported jurisdictions.

Legacy compliance platforms slow down page loads, require massive setup wizards, and charge extreme enterprise rates. We've built a faster, cleaner solution.

How ConsentKit Handles It
