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.
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.
Then:
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!
Huge thanks to:
Start selling to enterprise customers with just a few lines of code. Add Single Sign-On (and more) in minutes instead of months.

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 (cv01, cv02, etc), stylistic sets (ss01, ss02 , etc) and other font features (zero, onum, calt, etc), so that everyone can choose what’s best for them. How to enable
Some ligatures can be altered or enabled using stylistic sets/character variants:
Being a programming font, Fira Code has fantastic support for ASCII/box drawing, powerline and other forms of console UIs:
Fira Code is the first programming font to offer dedicated glyphs to render progress bars:
In action:
We hope more programming fonts will adopt this convention and ship their own versions.
Unicode coverage makes Fira Code a great choice for mathematical writing:

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_macos.sh
# build the font files
./script/build.sh
# install OTFs to ~/Library/Fonts
cp distr/otf/*.otf ~/Library/FontsAlternatively, you can build Fira Code using Docker:
# install dependencies in a container and build the font files
make
# package the font files from dist/ into a zip
make packageIf you want to permanently enable certain style sets or character variations, maybe because your editor of choice does not allow you to toggle these individually, you can provide the desired features as a comma separated list to the build script via the -f / --features flag.
Default: none.
To separate different versions of your font you can specify the desired font family name with the -n / --family-name flag. The special value 'features' will append a sorted, space separated list of enabled features to the default family name.
Default: "Fira Code"
You can also limit the font weights that will be created with the -w / --weights option.
Default: "Light,Regular,Retina,Medium,SemiBold,Bold"
# locally in your shell
./script/build.sh --features "ss02,ss08,ss10,cv03,cv07,cv14" --family-name "Fira Code straight" --weights "Regular,Bold"
# or via a docker container (creates the family name 'Fira Code cv01 cv02 cv06 cv31 onum ss01 ss03 ss04 zero')
docker run --rm -v "${PWD}":/opt tonsky/firacode:latest ./script/build.sh -f "cv01,cv02,cv06,ss01,zero,onum,ss03,ss04,cv31" -n "features"
# in Git Bash from Git for Windows, or any other MSYS2 based shell, you might need to disable path conversion
