PatternFly Icons vs Teenyicons (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 PatternFly Icons against Teenyicons 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. PatternFly Icons boasts an impressive 2,884 icons (licensed under MIT), while Teenyicons counters with 1,200 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 PatternFly Icons and Teenyicons, 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. PatternFly Icons primarily features a solid aesthetic, whereas Teenyicons leans toward a outline look.
PatternFly Icons is designed with strict geometric rules and a consistent grid, ensuring that all 2,884 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, Teenyicons offers a more distinct personality. With its 1,200 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 PatternFly Icons and the MIT license used by Teenyicons will ensure your project remains risk-free.
PatternFly 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.
Teenyicons 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 PatternFly Icons and Teenyicons.
- PatternFly Icons Performance: Because PatternFly 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.
- Teenyicons Performance: Similarly, Teenyicons 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 { ServerIcon } from '@patternfly/react-icons'
export default function App() {
return <ServerIcon />
}import { Home } from 'teenyicons'
export default function App() {
return <Home className='w-4 h-4' />
