Radix Icons is a 342-icon set by the team behind Radix UI, the unstyled accessible-by-default React component library that ships at WorkOS. The set is intentionally small: it covers only the common UI primitives — arrows, chevrons, files, status indicators, navigation, and form affordances — drawn on a 15×15 grid with a 1.5-pixel stroke. The minimal footprint makes Radix a strong companion to existing icon families: drop it next to Phosphor or Tabler when you want a single source of truth for component-level glyphs without adding hundreds of decorative icons to your bundle. Because the geometry is conservative and the design language is essentially typographic, Radix Icons read well at the 16–24 pixel sizes typical of buttons, inputs, and table actions, where heavier sets can feel oversized.
