Zilla is our core brand identity display typeface. We use it for our wordmark, for headlines and throughout our design. It's a contemporary slab serif that is based on Typotheque's Tesla. It's constructed with smooth curves and true italics, which gives text an unexpectedly sophisticated industrial look and a friendly approachability in all its weights. Zilla is an open source font and will be available to download by the end of February.
Fira Sans is our secondary typeface. It is a humanist sans-serif typeface designed by Erik Spiekermann and available under an open source license. Fira Sans is available in multiple weights and localized to Cyrilic and Indic languages.
