Note: Crisp fonts on Alacritty

February 27, 2023

I’m using Alacritty on the Mac and I noticed how the font rendering is much thicker than I’m used to on iTerm. On iTerm I use the “thin strokes” setting, which is not available in Alacritty.

Turns out, you can set it with:

defaults write org.alacritty AppleFontSmoothing -int 0

If you then log in and logout again, your Alacritty will be similar to the crispness you find in iTerm.

Some people like to have this kind of crispness across the entire OS. If you are one of them:

defaults write -g AppleFontSmoothing -int 0
