Webuum is a web framework designed specifically for building websites using native Web Components and platform APIs. It emphasizes minimalism and performance, targeting scenarios where the underlying web platform provides most of the required functionality. Webuum is not intended for building web applications, but rather for websites that benefit from a lightweight, declarative approach.
The framework operates without a virtual DOM or runtime abstraction, relying entirely on native browser capabilities. Its core is compact, with a gzipped size of just 1 kB, making it significantly smaller than some other frameworks. Webuum is optimized for server-rendered sites and aims to provide instant interactivity by loading only the necessary components. Developers use HTML-first patterns to define props, parts, and behaviors through attributes and native APIs, promoting a declarative style.
Webuum is designed to be framework-agnostic and does not require a bundler or build step. It can be integrated with any server-side rendering backend, such as PHP, Astro, Laravel, or Rails. The platform is also extensible, allowing optional integration of tools like Signals, LitHtml, or custom logic as needed. This flexibility ensures that developers can enhance functionality without being constrained by the framework.
The project is released under the MIT License, and its documentation is available for both general use and for large language models. cz.
