K4.pl is a showcase website for K4, the software house brand of Web Systems, and also a store for our WordPress and WooCommerce plugins and PrestaShop modules. We built it in a headless architecture: the Vue 3 front end fetches data via REST API from WordPress and WooCommerce, and after purchasing a license and paying through Stripe, the client manages domains in the panel, downloads packages, and receives automatic updates from our license server. The site operates in two languages, achieves 94-99 points in Google PageSpeed on mobile, and thanks to the llms.txt file, is also readable for AI models and agents.
