Under 25KB — loads faster than most WP themes
Cookie consent for WordPress that doesn't tank your page speed
Most WordPress cookie plugins ship 80–200KB of JavaScript and a heap of PHP overhead. CookieBoss ships an edge-compiled vanilla-JS banner under 25KB — with Google Consent Mode v2 built in, automatic cookie scanning, and full WP Consent API compatibility.
Why WordPress sites need a different CMP
WordPress runs 43% of the web. Most cookie consent plugins were built for it — and most of them slow it down.
Caching plugins fight back
Heavy CMP plugins inject inline scripts that break full-page caches and bloat HTML. CookieBoss is a single external <script> tag — cache-friendly by design.
Plugin updates pile up
Self-hosted CMPs need plugin updates for every security fix and config change. CookieBoss config pushes instantly from the cloud — the plugin almost never needs an update.
GTM & GCM v2 are mandatory
Google Consent Mode v2 has to fire before gtag.js. Most WP plugins get the order wrong and lose first-pageview attribution. CookieBoss fires GCM defaults inline before any tag loads.
WooCommerce + analytics
Cart-abandonment tools, Meta Pixel, GA4 ecommerce — all need consent state in milliseconds. CookieBoss exposes consent via the WP Consent API and via direct JS hooks for plugins that need it.
