Flagpack is a free, MIT-licensed set of 250+ country flag icons by Yummygum, optimized to stay crisp at small pixel sizes.
Being purpose-built and pixel-optimized for flags, rather than flags bundled as an afterthought in a general icon set, means better rendering at the tiny sizes flags are typically used at, like language switchers and country selects.
Good specifically for country and language selector UI: not a general-purpose icon set.
MIT licensed, no attribution required; ships as SVG plus Figma components, Sketch symbols, and framework packages for React, Vue, and Svelte.
