During March 2026, this developer delivered web support for Custom Variables in Paywalls within the RevenueCat/purchases-js repository, enabling dynamic, runtime-driven paywall text for web applications. They implemented a new customVariables property and integrated it into the paywall UI using React and TypeScript, aligning web functionality with existing mobile capabilities. The demo app was updated to allow configuration and preview of custom variables at runtime, providing a practical tool for developers and QA. Additionally, they stabilized the Cypress test suite by adjusting data-testid attributes, restoring reliable end-to-end validation and laying the groundwork for production-ready, cross-platform paywall experiences.
