About

Supersonic UI is a lightweight UI library with a focus on simplicity, performance, and ease of use. It provides a set of components and helpers that can be easily integrated into any web project without the need for complex build tools or frameworks.

Main motivation behind is to offer a practical and efficient solution for building content driven websites, and avoid build tools in the process.

There is a lot of other UI libraries out there, but most of them lack the features i need, or require build step and are based on less/scss. Supersonic UI has minimal css and its components can be overridden with css variables, and if you need utilities and don’t mind build step, you can just add TailwindCSS into the mix.

The library follows a progressive-enhancement approach. Its JavaScript components are activated through data-* attributes, keeping the markup simple, readable, and easy to extend.

It also includes a complete form layer with validation, submission handling, AJAX responses, and feedback patterns, giving you a practical toolkit for common website needs.
