Open Source User Interface (UI) Software

Material UI is an open-source React component library that implements Google's Material Design. It's comprehensive and can be used in production out of the box. A meticulous implementation of Material Design; every Material UI component meets the highest standards of form and function. Start quickly with Material Design or use the advanced theming feature to easily tailor the components to your needs. CSS utilities allow you to move faster and make for a smooth developer experience when styling any component. Reach out for the Figma Design Kit and the Sync plugin to bridge the gap between development and design when using Material UI.

Dash is a Python framework for building beautiful analytical web applications without any JavaScript. Built on top of Plotly.js, React and Flask, Dash easily achieves what an entire team of designers and engineers normally would. It ties modern UI controls and displays such as dropdown menus, sliders and graphs directly to your analytical Python code, and creates exceptional, interactive analytics apps. Dash apps are very lightweight, requiring only a limited number of lines of Python or R code; and every aesthetic element can be customized and rendered in the web. It’s also not just for dashboards. You have full control over the look and feel of your apps, so you can style them to look any way you want.

Atropos is a lightweight, open-source JavaScript library designed to add visually striking 3D parallax and hover effects to webpage elements — giving a sense of depth and interactivity when users hover or touch elements (cards, images, UI components). It works not only with vanilla JavaScript, but also provides integrations or support for modern frameworks (React, Vue, Web Components, etc.), making it easy to incorporate into a variety of web projects. Because Atropos is very small (just ~2 KB minified + gzipped) and has zero dependencies, it's ideal for performance-conscious applications and does not bloat bundle size. Developers can customize parameters — for example, perspective, rotation, scale, and responsiveness to pointer/touch events — to fine-tune how elements respond to user interaction.
