Cookie banners should protect websites — not slow them down
Most banners load 40–80 KB of JavaScript, destroy your Core Web Vitals, and block the First Contentful Paint. On top of that: without Google Consent Mode v2, you've been losing valuable conversion data since March 2024.
Compliso does it differently. Our banner weighs only ~6 KB — up to 13x smaller than other providers. It loads asynchronously, blocks nothing, and sets the Google Consent Mode v2 default state immediately on load. Your website stays fast, your data stays complete.
Everything a cookie banner needs
And nothing it doesn't. No bloat, no overhead.
~6 KB instead of 80 KB
Our banner is up to 13x smaller than the competition. Your website stays fast — Core Web Vitals stay green.
Script Blocking
Trackers are automatically blocked until the user consents. Even dynamically injected scripts. No manual tagging required.
Google Consent Mode v2
Set immediately — before any Google script loads. Your Ads and Analytics keep working, even when consent is denied.
3 Layouts
Bar (top/bottom), Box (corner), Wall (fullscreen). Colors, buttons, text — everything customizable in the visual editor.
Multilingual
English, German, and more languages. Automatic language detection based on your visitors' browser settings.
Accessible
WCAG 2.1 AA: Focus trap, keyboard navigation, screen reader support, high contrast. We sell accessibility — our banner lives it.
A/B Testing
Test different banner designs and find out which one delivers the highest consent rate. With statistical significance.
White Label
For agencies: Your logo, your colors. No "powered by Compliso" visible. Perfect for client projects.
