Lucide

Lucide is what Feather Icons should have become. A fork that kept going when Feather stalled, now packing 1,500+ clean, consistent SVG icons on a 24px grid with first-class React, Vue, and Svelte packages. It's the default icon set for shadcn/ui, which means it's quietly everywhere in modern web apps.

If you're building anything with Tailwind and shadcn, just use Lucide — it's already there. The icons are crisp, the bundle stays small at scale, and tree-shaking works properly. Heroicons (by the Tailwind team) is the polished alternative but tops out at ~300 icons. React Icons gives you 50,000+ from every set imaginable, but the bundle bloat is real. Tabler Icons has similar scale but less ecosystem momentum.

The catch: 1,500 icons sounds like a lot until you need something niche — think industry-specific or brand icons. You'll hit gaps. And because Lucide is so popular now, your app's icon aesthetic will look like everyone else's shadcn project.
