Best free programming fonts in 2018

This is not just a simple list of monospaced fonts for formatting code snippets. It’s a very selective set of typefaces that are designed and optimized for programming and contain ligatures for common programming multi-character combinations.

The ligatures are just a font rendering feature, so the code remains ASCII-compatible.

Fira Code

Fira Code is an extension of Fira Mono, that adds a lot of ligatures. For preview images, details, and pull requests visit the Fira Code Github repo.

Hasklig

Hasklig is a fork of Source Code Pro that adds ligatures for code.

Composite glyphs are problematic in languages such as Haskell that use operators like =>, –< or >>= extensively. The readability of complex code improves with ligatures.

Some Haskell programmers use Unicode symbols (⇒, ← etc.), which are valid in the GHC. However, the symbols are one character wide and eye-straining. And when displayed as substitutes to the underlying multi-character representation, the characters go out of alignment.

  • Includes 14 styles: 7 weights (ExtraLight, Light, Regular, Medium, SemiBold, Bold, Black) plus matching italics
