About

c15t is an open source framework that revolutionizes how developers handle cookie consent and privacy compliance. Unlike traditional solutions that impose black-box logic and vendor lock-in, c15t gives you complete control over the user experience while maintaining full compliance. Key advantages: The framework is fully tree-shakable with minimal bundle size, making it significantly faster than alternatives like OneTrust or Usercentrics. You can scaffold a complete setup in seconds using the CLI or integrate the headless logic for maximum flexibility. c15t handles consent states, blocks requests intelligently, and provides native components for popular frameworks while maintaining the developer-friendly approach that modern web applications demand.
