Iconify is a free, open-source platform, not a single icon set, that unifies 200+ independent open-source icon sets (Material Design, Feather, Phosphor, Heroicons, and many more), totaling 300,000+ icons, accessible via one consistent API, a Figma/FigJam widget, and framework components.
The value is entirely in unification: one search interface, one icon-component API, and one Figma widget cover icon sets that would otherwise each need separate installation and syntax.
Good for teams that want the flexibility to pull from many different icon aesthetics through one tool, rather than committing to a single icon set's style upfront.
Because it aggregates 200+ independently licensed icon sets, license terms vary by set, mostly MIT, Apache, or similarly open, but always check the specific set; free with no signup required.
150,000+ open-source icons inside Figma, spanning Material, Heroicons, Feather, Phosphor, and dozens more icon sets.
