Google Fonts is a free library launched by Google in 2010 that lets you browse, test and use more than a thousand open source font families, on a website as in any software. It is widely used for its variable fonts and its coverage of the world's languages and scripts.

Publisher and date
Publisher: Google, United States.
Date: 2010.
Type of tool: Open source font library and web font hosting service.
Strengths
An entirely free and open catalogue, many variable fonts, very broad coverage of the world's languages and scripts, and direct integration into tools such as Figma.
Who it is for
Everyone, from web developers to graphic designers, including companies looking to avoid licensing fees.
Pricing model
Free, under open source licences. In Europe, a German court ruled in 2022 that loading fonts from Google's servers could raise issues under the GDPR: it is therefore recommended to host them directly on your own website.
Signature typefaces
Roboto, Open Sans, Montserrat, Poppins and Inter.
