Heroicons is a clean, hand-crafted library of SVG interface icons created by the Tailwind CSS team, designed for modern web apps, dashboards, and design systems. The set includes hundreds of consistent outline and solid icons optimised for React, Vue, and plain SVG workflows, making them ideal for developers and UI designers building scalable interfaces. Importantly, Heroicons are released under a permissive Creative Commons–style open licence (MIT), allowing creators to freely use, modify, and integrate the icons in both personal and commercial projects without restriction.
