Wakamai Fondue

Wakamai Fondue is a free browser tool by Pixel Ambacht: drop in a font file and it lays out everything inside it, from characters and supported languages to OpenType features and variable axes. Each feature can be previewed and toggled, and the tool generates the CSS needed to use it, so designers find stylistic sets and alternates they did not know a font had. Its retro fondue-dinner homepage makes a dry technical task feel approachable.
