c15t

c15t is a developer-first, open-source consent management platform designed to help modern web applications manage user privacy and compliance, especially for things like cookie banners, consent dialogs, and script loading in a way that supports GDPR and other privacy regulations. Rather than relying on heavy third-party scripts or services, it offers a flexible, headless engine that web teams can integrate directly into their front-end and edge stacks with minimal overhead, giving full control over user experience and data handling. c15t runs entirely in the front end or at the edge, blocking or allowing scripts based on user decisions and tracking those states for observability and auditing. It provides framework-agnostic core logic as well as adapters and components for popular frameworks like React and Next.js, making it easy to scaffold banner UIs, preference centers, and consent dialogs while keeping performance high and bundle sizes low.
