  Commit Mono is an anonymous and neutral programming typeface.

The Commit Mono font has a feature that it calls "smart kerning". Monaspace has a similar feature that it calls "texture healing." Characters are moved around slightly, or swapped out for a slightly larger or smaller character to even out the spacing, for example, when a wide character like an 'm' is followed by a narrow character like an 'l'.

  Display typographical ligatures in Emacs

Apparently "smart kerning" uses the ligatures mechanism. I use Mickey Peterson's ligature.el package for ligatures support. To get the smart kerning to work I added more ligatures by hand using this package. For example the website shows the effect when you type "Moi": the "o" will shift a bit away from the "M" when you type the "i". To get that to work I added a "Moi" ligature:
