Lucide

Lucide is a community-maintained fork of Feather Icons, grown from a few hundred icons into one of the most popular open-source line icon sets for modern web development. Every icon follows the same strict design rules — a 24px grid, 2px stroke, and rounded line caps — so the set stays visually consistent across any interface, from SaaS dashboards to documentation sites.

Official packages are maintained for React, Vue, Svelte, Solid, Angular, Preact and plain JavaScript, all fully tree-shakeable so you only bundle the icons you actually import. Icons can be customized in size, color and stroke width, and an absolute stroke width option keeps line weights consistent at any scale.
