Material UI vs. Open Props

What is Material UI ?

Material UI also known as MUI is a popular ui framework that helps developers build modern, good-looking websites. MUI provides a collection of ready-made components like buttons, forms, menus, and cards that follow Google’s Material Design which is a clean and consistent visual style.

As it built on React, MUI saves you time by letting you use these predesigned parts instead of starting everything from scratch.

Whether you're building a small personal project or a large web application, MUI helps make your site look professional and work well on both computers and mobile devices.

Key Features of Material UI

×

• Rich Component Set: Buttons, dialogs, data grids, pickers, more.
• Accessibility: Prefers WCAG best practices and ARIA attributes.
• Material Theming: Customizable palettes, typography, and spacing.
• CSS-in-JS: Dynamic styling via Emotion or styled-components.
• Dark Mode Support: Easy theme toggling built-in.
• Tree Shaking: Supports importing specific components to reduce bundle.

Advantages of Material UI

• Comprehensive Component Library: It covers almost every common UI need: buttons, forms, grids, modals, tables, tooltips, and more. It constantly updated with new components and features.
• Customizable Themes: Lets you easily change colors, typography, spacing, and more. plus you can create your own design system or match an existing brand style as well.
• Enterprise-Ready: It is used in production by large companies and apps as its stable, well-documented, and actively maintained by a strong development team.
• Responsive Design Support: Components that adapt to different screen sizes with built-in responsive utilities.
• Internationalization (i18n) Support: Easily supports multiple languages and right-to-left (RTL) layouts.
• Layout System: Built-in grid and flexbox systems simplify layout creation.
• Seamless Integration with React: It is designed specifically for React, with hooks, states, and props handled smoothly.

Disadvantages of Material UI

• Styling Confusion: Multiple styling options like styled components, emotion, sx prop, makeStyles etc, can be overwhelming or inconsistent.
• Learning Curve: New developers may find MUI's system like themes, styling with sx, custom breakpoints complex at first time.
• Some Features Are Paid: MUI X Pro and Premium components like advanced data grid require a commercial license.
• Look Can Be Generic: Many apps using MUI may look similar if not customized enough. Extra effort is needed to give your app a unique appearance.
• Too Tied to React: MUI only works with React. Not usable in plain HTML/JS or other frameworks like Vue or Angular.
• Bundle Size: It can increase the size of your app bundle if not optimized specially with MUI X.

What is Open Props?

Open Props is a modern CSS framework built entirely around CSS custom properties (variables). Instead of sending prebuilt UI components or heavy utility classes, it provides a set of reusable design tokens that you can apply anywhere. Think of it as a toolbox of modern CSS features rather than a ready-made UI kit.

It’s not a traditional framework like Bootstrap or Tailwind. Instead, it’s closer to a design system foundation—a library of variables for colors, typography, shadows, gradients, animations, spacing, and sizes. Developers can use these variables in raw CSS, Sass, or even combine them with other frameworks.

Because it’s framework-agnostic, Open Props works well with plain HTML, React, Vue, Angular, or even with utility-first libraries like Tailwind.

Key Features of Open Props

×

• Design Tokens Out-of-the-Box: Colors, gradients, fonts, shadows, borders, animations, spacing.
• Framework-Agnostic: Works with vanilla CSS, SCSS, PostCSS, Tailwind, or any frontend setup.
• Utility Classes (Optional): Comes with optional helpers like margin: var(--size-3).
• Theming Made Simple: Supports dark/light mode with just a few variable overrides.
• Modern CSS-Only: No JavaScript, only pure CSS properties.
• Lightweight by Design: Extremely small bundle size compared to component-heavy frameworks.
• CDN Ready: Drop in via a <link> or import with NPM.

Advantages of Open Props

• Flexible: Can be used standalone or alongside other CSS frameworks.
• Theming Support: Switch to dark mode or brand colors by redefining tokens.
• Beginner-Friendly: Easy for anyone who already knows CSS variables.
• Ultra Lightweight: Just variables, no unnecessary bloat.
• Encourages Best Practices: Pushes developers towards scalable, token-based design systems.
• Easy to Customize: Override props once to apply across your project.

Disadvantages of Open Props

• Small Community: Limited templates, examples, and resources compared to Bootstrap/Tailwind.
• Not Plug-and-Play: Great for design systems, but not ideal if you want instant UI.
• No Prebuilt Components: You’ll need to design buttons, modals, navbars yourself.
• Challenging Learning Curve for Beginners: Requires understanding of CSS variables and design tokens.
