Iosevka already provides webfonts, but there is no hosting option available. The issue to add Iosevka font to fonts.google.com doesn't seem to be processed. Therefore, I create my own Iosevka webfonts hosting using Github Page (inspired by Pvinis).
I've created a legacy version, but its massive size causes Github Pages build issue. That's why I created Iosevka-webfonts organization which contains bunch of repositories. Each repository corresponds to an Iosevka webfont variant.
The update process is processed in update-centre repository. It is scheduled to check for the new Iosevka release, then fetches webfont-type assets, and pushes changes to corresponding repository automatically.
Hope you guys enjoy it!
