Typekit now supports wildcard domains
We’ve just added a feature that should make using Typekit on subdomains way easier. You can now use * as a wildcard in the authorized domains that can link to a font.
This makes it possible to use Typekit on services where every user has their own subdomain (*.myservice.com). It also gives you the flexibility to get Typekit to work on all of your Development and QA servers (*.dev.example.com, *.qa.example.com).
You can manage your authorized domain list from the “Kit Settings” tab in the Kit Editor.
