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