Best alternatives to c15t in 2026
Every website needs a cookie consent banner these days, but the usual options are either a heavyweight third-party script that adds load time and looks out of place on your site, or building consent logic from scratch, which is easy to get legally wrong. c15t splits the difference: it's an open-source toolkit built specifically for developers using React, Next.js, or plain JavaScript, giving you either ready-made UI components or a headless API if you want full control over the look. c15t (Apache 2.0 licensed) provides consent-aware script loading for analytics, ad pixels, and tag managers, with support for the IAB TCF 2.3 standard and Google Consent Mode v2. It ships framework-specific packages (@c15t/react, @c15t/nextjs, @c15t/scripts, @c15t/iab) and can run fully self-hosted, via a managed backend, or in offline mode. It has around 1,800 GitHub stars and is used on 2,100+ sites including Expo, Cal.com, and Zed. c15t is built by Inth (formerly Consent.io), a Y Combinator company also building a broader enterprise privacy governance platform.
