Remix Icon is an open-source "neutral-style" system icon set, now past 3,200 icons, each drawn in both outlined and filled versions on a 24x24 grid.
Deliberately neutral styling (no strong personality or trend-specific flourish) makes these icons easy to drop into an existing design system without clashing with other UI elements.
Good default for general product UI work where the goal is icons that stay out of the way rather than make a style statement.
Free for personal and commercial use with attribution appreciated but not required; be aware the project's license terms have shifted across versions (older releases reference Apache 2.0, current releases use a dedicated Remix Icon License), so it's worth checking the version you install.
