PolyCMS is an open-source content management system for modern web applications, inspired by the WordPress plugin and theme ecosystem but built on top of the Laravel framework. It is designed to provide a complete foundation for content publishing, e-commerce, multi-language support, and extensible module architecture — powered by a Vue 3 admin panel with data served entirely through RESTful APIs.
Whether you're building a blog, a documentation site, an online store, or a multi-tenant SaaS platform, PolyCMS aims to give you a comprehensive starting scaffold so you can ship quickly and extend easily through integrated modules and themes. In particular, themes in PolyCMS follow a multi-theme architecture — one Main theme and an unlimited number of Sub themes can run side by side on the same installation.
We hope this ready-made foundation proves useful for building your next website, blog, or web app, saving you from having to start completely from scratch.
