Introducing the first platform that produces clean code directly from design elements, Overlay serves as a plugin that transforms components from Figma or Sketch into React, Vue.js, or HTML clean code components. By instantly generating developer-friendly web components from design tools, Overlay streamlines the integration process for both designers and developers. This documentation is designed to help users speed up their web design integration, ensuring a smoother workflow. We created Overlay to empower designers to independently construct pixel-perfect components without requiring knowledge of modern JavaScript frameworks. Additionally, we believe that front-end developers should focus on high-priority tasks such as performance optimization, SEO, and business logic rather than converting UX designs into code. Overlay Playgrounds are design files filled with numerous component examples that are ready for Overlay, along with comprehensive explanations that guide users in creating these components themselves and mastering the tool. While it's still feasible to utilize Overlay with other configurations, it may introduce some additional workload after obtaining the component code. Looking ahead, we plan to continually expand our range of setups to enhance versatility and user experience. This commitment to improvement will ensure that both designers and developers can benefit from a more efficient workflow in the future.
