Material Design Icons

Material Design Icons (MDI), maintained by the Pictogrammers community, is one of the largest open-source icon libraries available: 7,638 SVG glyphs drawn in the Material Design style and distributed under Apache 2.0. The catalog began as a community-driven complement to Google's official Material Icons, filling in gaps the official set didn't address, and has since grown to cover specialized verticals like cryptocurrency, weather, music notation, sports, food, and home automation that Google's set still doesn't include. Every icon is on a 24×24 viewport with rounded edges, even visual weight, and a familiar Material idiom. Pictogrammers publishes React, Vue, Angular, and web-component bindings, plus a font, an SVG sprite, and individual SVGs, so integration paths exist for essentially any toolchain.
