With Animate, you get direct access to fonts from Adobe Fonts, a subscription service for premium commercial fonts. You can try a limited selection of fonts from the Adobe Fonts library with any level of Creative Cloud plan. If you have subscribed to a paid plan, you have access to the full library with thousands of fonts. See Using web fonts for step-by-step instructions on how to use Adobe Fonts with Animate.
There are no limits on the number of fonts that can be activated at the same time and no more limits on the number of monthly page views for web fonts.
