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 Iconoir against Lucide 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. Iconoir boasts an impressive 1,384 icons (licensed under MIT), while Lucide Icons counters with 1,960 highly-polished icons (licensed under ISC).

Below, we dive into the technical details: bundle size impacts, tree-shaking capabilities, TypeScript support, explicit commercial licensing rules, and real-world implementation examples.

⚠️ Upgrading to Lucide React v1.0?

The lucide-react 1.0 release introduced breaking changes — many icons were renamed (e.g. BarChart2ChartBar, PlusCircleCirclePlus). If your build fails with module '"lucide-react"' has no exported member, read our migration guide.

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 Iconoir and the ISC license used by Lucide Icons will ensure your project remains risk-free.

IconoirMIT

Iconoir 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.

✓ COMMERCIAL USE
Free for personal, commercial, and SaaS projects without recurring fees.
Lucide IconsISC

Lucide Icons uses the ISC License, which is functionally equivalent to the MIT License but written in simpler language. You are free to use it in commercial projects, modify icons, and redistribute without restriction. The only condition is preserving the copyright notice.

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 Iconoir and Lucide Icons.

  • Iconoir Performance: Because Iconoir 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.
  • Lucide Icons Performance: Similarly, Lucide 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.

    </div>
  )
}
