Best Icon Libraries for Web and Product Design in 2026
Free icon libraries mostly differ in style and coverage: Heroicons (from the Tailwind CSS team), Lucide (a community fork of Feather), Phosphor Icons (multiple weights), and Tabler Icons (5,000+ on a consistent grid) each offer a distinct visual style at no cost. Iconify is different: it's a meta-library giving API access to icons from 200,000+ icons across every major set, including all of the above.
