Elusive Icons vs Untitled UI Icons (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 Elusive Icons against Untitled UI Icons 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. Elusive Icons boasts an impressive 304 icons (licensed under OFL-1.1), while Untitled UI Icons counters with 1,179 highly-polished icons (licensed under MIT).
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 Elusive Icons and Untitled UI Icons, 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. Elusive Icons primarily features a solid aesthetic, whereas Untitled UI Icons leans toward a outline look.
Elusive Icons is designed with strict geometric rules and a consistent grid, ensuring that all 304 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, Untitled UI Icons offers a more distinct personality. With its 1,179 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 OFL-1.1 license used by Elusive Icons and the MIT license used by Untitled UI Icons will ensure your project remains risk-free.
Elusive Icons uses the OFL-1.1 license, a permissive open-source license that allows free commercial use in web and mobile applications.
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.
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 Elusive Icons and Untitled UI Icons.
- Elusive Icons Performance: Because Elusive 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.
- Untitled UI Icons Performance: Similarly, Untitled UI Icons is fully tree-shakable. Your Webpack or Turbopack build step will strip out any unused icons, ensuring your First Contentful Paint (FCP) metrics remain exceptional.
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 'elusive-icons/css/elusive-icons.min.css'
export default function App() {
return <i className='el el-home'></i>
}import { Home01 } from '@untitledui/icons'
export default function App() {
return <Home01 size={24} color='currentColor' />
