This is a super cool website, thank you for sharing it.

My go-to in most situations is still the Source Pro family, but so many people seem to swear by Fira Code that I need to give it a try. (Although I'm not yet sold on ligatures)

Source Code Pro just seems to fit all my applications well - terminals, emacs, vim, visual studio code. Plus the serif and sans serif versions look good to me in the browser.
