I should mention that I just added the following to my ‘Favourite ebook typefaces’ post from earlier this year:
Nico Verbruggen’s ebook fonts [Added 17 Oct 2026]
Nico Verbruggen, a software developed in Belgium, has taken a bunch of excellent open-source typefaces and modified them to work better on ereaders (focusing mostly on Kobo ereader devices).
You can download these modified typefaces from his ebook-fonts GitHub repository and you can see those typefaces in action (to pick your favourites) on his interactive showcase website.

So if the typefaces listed here don’t do it for you, you should definitely go there to take a look.
