The Developer-First Cookie Banner
c15t is an open source framework for managing cookies, consent, and privacy compliance. Built for modern web apps. It’s fully customizable, framework-agnostic, and designed to give developers full control over the user experience without black-box logic or vendor lock-in.
import {
ConsentManagerProvider,
CookieBanner,
ConsentManagerDialog
} from "@c15t/nextjs";
export default function App() {
return (
<ConsentManagerProvider options={{
mode: 'c15t',
backendURL: process.env.NEXT_PUBLIC_C15T_URL
}}>
{children}
<CookieBanner />
<ConsentManagerDialog />
</ConsentManagerProvider>
);

Why c15t?
c15t runs entirely in your frontend or edge stack, blocking requests and managing consent states with minimal overhead. Use our CLI to scaffold a cookie banner in seconds, or drop in the headless logic and fully control the experience yourself.
Faster than your Lighthouse score can blink. Minimal bundle size, fully tree-shakable. Built for speed, not bloat.
Bring your design tokens, themes, or unhinged CSS experiments. You're in control, we don't fight your stack.

Yes, please! Given the frustration we've all experienced, it blows my mind that no one has fixed this yet. Where have you been all this time? 😅

It was about time someone did that. Current solutions are too bloated or just sucks.
