FrontWing is an experimental headless frontend for Sylius, built with React, Remix, Vite, and Bootstrap 5. It implements the full buyer journey, including homepage, product catalog, cart, checkout, and customer account, entirely via Sylius API v2. Designed with performance and SEO in mind, it supports server-side rendering and PWA architecture. The project provides a solid foundation for building modern storefronts and can be extended to support other eCommerce platforms as well.
