Lucide Icons vs Octicons (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 Lucide Icons against Octicons 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. Lucide Icons boasts an impressive 1,960 icons (licensed under ISC), while Octicons counters with 280 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.
⚠️ Upgrading to Lucide React v1.0?
The lucide-react 1.0 release introduced breaking changes — many icons were renamed (e.g. BarChart2 → ChartBar, PlusCircle → CirclePlus). If your build fails with module '"lucide-react"' has no exported member, read our migration guide.
TECHNICAL FEATURE COMPARISON
When comparing Lucide Icons and Octicons, 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 ISC license used by Lucide Icons and the MIT license used by Octicons will ensure your project remains risk-free.
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.
Octicons 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 Lucide Icons and Octicons.
- Lucide Icons Performance: Because Lucide 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.
- Octicons Performance: Similarly, Octicons 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 'lucide-react'
export default function App() {
return <Home size={24} />
}import { RepoIcon } from '@primer/octicons-react'
export default function App() {
return <RepoIcon size={16} />
