The zero really stands out and looks quite different from zeroes in most other fonts. The addition of the slash means you'll never have to second guess if that character is actually an "O" or if it is a "0".

Because it's open source, Anka/Coder is freely available to anyone.

Anka/Coder has just the right balance between style and readability.

Condensed and, even to a greater extent, narrow versions allow for compact lines without sacrificing readability.
