Source Foundry

Hack includes monospaced regular, bold, oblique, and bold oblique sets to cover all of your syntax highlighting needs.

Just installed it. I like how it looks so far.

Free and open source

Tried it on my sublime. This is beautiful!

I also find it good for copywriting (not just coding) because it's a bit softer than normal "coding" fonts.

Just installed it to Xcode. Looks beautiful!

Having a little trouble getting on board with the zero. Interestingly generous line-spacing, compared to other fonts in its family!
