The problem with codingfont.com is that it overrides the line height, so you won't see what the line height will actually look like in your editor, which is something that I care about.
If your editor doesn't allow you to override the font's default line height (to whatever you like), there's a nice little tool you can use to do this to the font file itself: https://github.com/source-foundry/font-line
This is also useful for mixing and matching fonts. Nicolas Rougier uses this in NANO Emacs to hack the Victor Mono italic to have the same line height as Roboto Mono.
I think the point is that their editor does, but the website above for previewing doesn't. If you have to download and and edit the font file manually to get the website to preview it, you might as well just preview it in the editor instead.
Thanks for the send. I'm new to choosing a font for my editors, and just went through the tournament. I've got to say, Inconsolata is quite a finessed font for coding. It definitely seems to work well for me.
I do wish that site let you "exclude" certain options so they never appear in the tournament at all. It would have saved time, one or two are so awful they aren't work doing comparisons on.
It even includes Anka/Coder, my personal favorite. It doesn't include anything but Regular, not its variants like Narrow, but still quite a complete project.
Playing the font tournament is fun, especially with the font names turned off. I ended up with Fira Code (my current preference) vs Fira Mono in the final round.
i downloaded my winner, installed it, changed my editor... and immediately went back to Monaco :) there's a lot of cognitive momentum to overcome in switching fonts.
