The Churnkey SDK is open source and actively developed, starting with React. More on the way. Use the drop-in component, the headless hook, or the core state machine — and optionally connect to Churnkey for analytics and AI-powered retention.

Three ways to integrate

  • Drop-in component

    Styled, accessible, production-ready out of the box.

  • Headless hook

    Bring your own UI; keep the logic and analytics.

  • Core state machine

    Framework-agnostic primitive for advanced wiring.
