Fira Code: free monospaced font with programming ligatures
Problem
Programmers use a lot of symbols, often encoded with several characters. For the human brain, sequences like ->
, <=
or :=
are single logical tokens, even if they take two or three characters on the screen. Your eye spends a non-zero amount of energy to scan, parse and join multiple characters into a single logical one. Ideally, all programming languages should be designed with full-fledged Unicode symbols for operators, but that’s not the case yet.
Solution
Fira Code is a free monospaced font containing ligatures for common programming multi-character combinations. This is just a font rendering feature: underlying code remains ASCII-compatible. This helps to read and understand code faster. For some frequent sequences like ..
or //
, ligatures allow us to correct spacing.

Fira Code is a personal, free-time project with no funding and a huge feature request backlog. If you love it, consider supporting its development via GitHub Sponsors or Patreon. Any help counts!
What’s in the box?
Left: ligatures as rendered in Fira Code. Right: same character sequences without ligatures.
Fira Code comes with a huge variety of arrows. Even better: you can make them as long as you like and combine start/middle/end fragments however you want!
Fira Code is not only about ligatures. Some fine-tuning is done for punctuation and frequent letter pairs.
Fira Code comes with a few different character variants, so that everyone can choose what’s best for them. How to enable
Being a programming font, Fira Code has fantastic support for ASCII/box drawing, powerline and other forms of console UIs.
Unicode coverage makes Fira Code a great choice for mathematical writing.

Building Fira Code locally
In case you want to alter FiraCode.glyphs and build OTF/TTF/WOFF files yourself, this is the setup I use on macOS:
# install all required build tools ./script/bootstrap # build the font files ./script/build # install OTFs to ~/Library/Fonts ./script/install
