Two variable, open source fonts from github
Mona Sans is described as a strong and versatile typeface inspired by industrial-era grotesques. It is designed to work well for product, web, and print.
Hubot Sans is described as Mona’s robotic sidekick, with more geometric accents giving it a technical and idiosyncratic feel suitable for headers and pull quotes.
Both fonts come in a variable font format, allowing control over weight, width, and slant through a single font file. This provides thousands of style variations.
