What c15t is
c15t is an open-source consent management project for teams adding privacy controls to applications. It offers components and APIs for consent banners, preference centres, consent state, and script loading. Teams can use a managed Inth backend or host the backend themselves; the self-hosted option provides consent storage, geolocation, audit logging, and policy management on the team's infrastructure. The script loader can check consent before injecting eligible scripts, unload scripts after consent is revoked, or send consent updates to scripts that remain loaded.
Documented integrations include Google Tag Manager, Google Tag, Meta Pixel, analytics tools, ad pixels, and chat widgets. React and Next.js packages include consent-aware Google Maps and YouTube components. The project lists integrations for frameworks including Next.js, React, JavaScript, TanStack Start, Nuxt, Vue, Astro, Svelte, and SvelteKit. It supports regional opt-in, opt-out, or no-banner experiences, as well as custom themes, styling, translations, and headless consent interfaces. The homepage describes support for IAB TCF 2.4, Google Consent Mode v2 signals, and more than 30 languages, including right-to-left text. The open-source packages cost nothing under the Apache 2.0 license. c15t supplies implementation tools, not legal advice; teams remain responsible for setting consent rules appropriate to their products and users.
