Devicons 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 Devicons 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. Devicons boasts an impressive 800 icons (licensed under MIT), 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 Devicons 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. Devicons primarily features a original aesthetic, whereas Untitled UI Icons leans toward a outline look.
Devicons is designed with strict geometric rules and a consistent grid, ensuring that all 800 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 MIT license used by Devicons and the MIT license used by Untitled UI Icons will ensure your project remains risk-free.
Devicons 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.
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 Devicons and Untitled UI Icons.
- Devicons Performance: Note that Devicons does not natively support tree-shaking out of the box in all environments. This means you must be careful with your import syntax to avoid accidentally bundling all 800 icons.
- 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.
