Icon kits
Only the icons you use.
Pick them, name the kit, and get a font with just those: three icons weigh under a kilobyte. WOFF2 for the web, TTF for apps, the CSS (with Font Awesome’s class names if you like) and each icon’s character, in one ZIP. Free, MIT, nothing to sign up for.
As a link
The same kit from a URL, for a build step or an agent: the names, the kit’s name and whether to include Font Awesome’s classes.
