Google Workspace for Education and Google Workspace for Nonprofits (for accredited 501(c)(3) nonprofit entities) are free and offer the same amount of storage as other Google Workspace accounts.[1]
In addition to shared apps (calendar, docs, etc.), Google provides Google Workspace Marketplace, an app store for Google Workspace users. It contains various apps, both free and paid, which can be installed to customize the Google for Education experience for the user.[2]
