Untitled UI Icons vs Remix Icon (2026)
When building modern web applications, choosing the right icon library can significantly impact both your application's aesthetic and its performance. In this comprehensive comparison, we pit Untitled UI Icons against Remix Icon to help you make an informed decision for your React, Next.js, Vue, or Svelte project.
Together, these libraries represent some of the most popular open-source UI assets available today. Untitled UI Icons boasts an impressive 1,179 icons (licensed under MIT), while Remix Icon counters with 3,229 highly-polished icons (licensed under Apache 2.0).
Below, we dive into the technical details: bundle size impacts, tree-shaking capabilities, TypeScript support, explicit commercial licensing rules, and real-world implementation examples.
TECHNICAL FEATURE COMPARISON
When comparing Untitled UI Icons and Remix Icon, developer experience features like TypeScript definitions and tree-shaking support are just as important as the icon count. Review the matrix below to see how they stack up.
DESIGN AESTHETICS & VISUAL STYLE
Beyond the code, the visual identity of your application is heavily influenced by your choice of iconography. Untitled UI Icons primarily features a outline aesthetic, whereas Remix Icon leans toward a line look.
Untitled UI Icons is designed with strict geometric rules and a consistent grid, ensuring that all 1,179 icons share the same visual weight. This makes it particularly well-suited for professional dashboards, enterprise SaaS products, and minimal user interfaces.
On the other hand, Remix Icon offers a more distinct personality. With its 3,229 carefully crafted icons, it can bring warmth and character to consumer-facing mobile apps, marketing websites, and creative portfolios.
LICENSING & COMMERCIAL USE DEEP-DIVE
Legal compliance is critical when selecting assets for a commercial software project. Understanding the nuances between the MIT license used by Untitled UI Icons and the Apache 2.0 license used by Remix Icon will ensure your project remains risk-free.
Untitled UI Icons uses the MIT License — one of the most permissive open-source licenses. You can use it in any commercial project, modify the icons, and redistribute them freely. The only requirement is preserving the copyright notice in copies of the software.
Remix Icon uses the Apache 2.0 License, which allows free commercial use, modification, and distribution. It also includes an express patent grant. You must include a copy of the license and provide attribution when redistributing original files.
PERFORMANCE & BUNDLE SIZE
Modern front-end frameworks like React and Next.js heavily penalize large JavaScript bundles. This makes tree-shaking—the ability of a bundler to remove unused code—a crucial factor when choosing between Untitled UI Icons and Remix Icon.
- Untitled UI Icons Performance: Because Untitled UI Icons supports tree-shaking, importing a single icon will only add a tiny fraction of a kilobyte to your final bundle. You can safely install the entire package without performance concerns.
- Remix Icon Performance: Conversely, Remix Icon lacks complete tree-shaking support. To maintain high performance, consider importing individual SVG files directly rather than using the main package export.
REACT IMPORT SYNTAX & INTEGRATION
Here is how you actually write the code to import and use each library in a React or Next.js component. Both libraries offer distinct APIs and integration patterns.
import { Home01 } from '@untitledui/icons'
export default function App() {
return <Home01 size={24} color='currentColor' />
}import 'remixicon/fonts/remixicon.css'
export default function App() {
return <i className='ri-home-line'></i>
