Feather Icons vs Simple 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 Feather Icons against Simple 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. Feather Icons boasts an impressive 287 icons (licensed under MIT), while Simple Icons counters with 3,200 highly-polished icons (licensed under CC0 1.0 (Public Domain)).
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 Feather Icons and Simple 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.
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 Feather Icons and the CC0 1.0 (Public Domain) license used by Simple Icons will ensure your project remains risk-free.
Feather 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.
Simple Icons uses CC0 1.0 (Public Domain). All copyrights have been waived. You can copy, modify, distribute, and use the icons for any purpose — including commercial — without attribution.
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 Feather Icons and Simple Icons.
- Feather Icons Performance: Because Feather 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.
- Simple Icons Performance: Similarly, Simple 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 { Home } from 'react-feather'
export default function App() {
return <Home size={24} />
}import {
SiGithub,
SiVercel,
SiStripe,
SiReact,
SiNextdotjs,
SiTailwindcss,
} from '@icons-pack/react-simple-icons'
// All components use 'Si' prefix + PascalCase brand name
export function TechStack() {
return (
<div className="flex items-center gap-4">
{/* Use currentColor — inherits from parent */}
<SiGithub size={24} />
<SiVercel size={24} />
{/* Use official brand color */}
<SiStripe size={24} color="#635BFF" />
<SiReact size={24} color="#61DAFB" />
{/* Social links row */}
<a href="https://github.com" aria-label="GitHub">
<SiGithub size={20} className="text-gray-600 hover:text-gray-900" />
</a>
</div>
)
