Bunny Fonts is a EU-based font service that is designed to be a direct drop-in replacement for Google Fonts. The service is offered for free by the content delivery network (CDN) provider Bunny. Simply swap "https://fonts.bunny.net/css" in place of "https://fonts.googleapis.com/css" on your website's source code to use Bunny Fonts instead of Google Fonts.
European alternatives to Google Fonts
Google Fonts is a font service by USA-based company Google. The fonts on the service are all under a free software license. Which means they can be freely used. Currently it is only allowed to use the service in the European Union with the user's consent or with a legitimate interest.
This pages lists European Google Fonts alternatives from companies based in a member state of the European Union (EU) or the European Free Trade Association (EFTA).
Self-hosted & Open Source
