Heroicons vs Devicons (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 Heroicons against Devicons 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. Heroicons boasts an impressive 324 icons (licensed under MIT), while Devicons counters with 800 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 Heroicons and Devicons, 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. Heroicons primarily features a outline aesthetic, whereas Devicons leans toward a original look.
Heroicons is designed with strict geometric rules and a consistent grid, ensuring that all 324 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, Devicons offers a more distinct personality. With its 800 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 Heroicons and the MIT license used by Devicons will ensure your project remains risk-free.
Heroicons 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 Heroicons and Devicons.
- Heroicons Performance: Because Heroicons 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.
- Devicons Performance: Conversely, Devicons 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 { HomeIcon } from '@heroicons/react/24/outline'
export default function App() {
return <HomeIcon className='h-6 w-6' />
}<!-- Font class usage --> <i class="devicon-react-original colored"></i> <i class="devicon-typescript-plain colored"></i> <!-- SVG usage --> <img src="https://cdn.jsdelivr.net/gh/devicons/devicon/icons/react/react-original.svg" width="24" />
