Lucide Icons
Lucide is a community-driven fork of Feather Icons created when Feather development slowed, and is now one of the most actively developed open icon libraries in the ecosystem. It carries forward Feather's tight 24×24 grid and 2-pixel stroke discipline while continuously expanding the catalog to 1,771 icons. The ISC license is functionally equivalent to MIT for permissive commercial reuse. Lucide ships first-party packages for React, Vue, Svelte, Angular, Solid, Preact, React Native, and Flutter, plus plain SVGs and an icon font, which is one of the broadest framework matrices among free icon libraries. The combination of Feather's familiar geometry, active maintenance, and turnkey framework support makes Lucide a strong default — particularly for React projects and design systems that want a single library across the entire stack.
