Overview

c15t is an open source consent management framework for web apps. It ships React and Next.js components — ConsentManagerProvider, ConsentBanner and ConsentDialog — plus a headless core for other frameworks, and gates third-party scripts such as Meta Pixel behind consent. It runs against a hosted backend or self-hosted, and a CLI scaffolds an initial setup.

Best for: Development teams that want a code-controlled cookie consent banner in modern web apps
Pricing: The captured page shows no prices; it describes c15t as open source with a self-host option, but gives no figures for the hosted mode.
Runs on: Self-hostedCLI
