c15t is an open-source cookie consent manager and consent management platform for JavaScript, offering GDPR-compliant cookie banners, preference dialogs, and consent-gated script loaders. It supports multiple frameworks (React, Next.js, Vue, Nuxt, Svelte, Astro, etc.), server-side consent resolution, and integrates with Google Consent Mode v2, IAB TCF, and 40+ analytics/marketing vendors. Its self-hostable backend and policy-based regional rules make it a compelling alternative to proprietary CMPs.
