iCloud for Developers
Keep your apps connected and up to date across iOS, macOS, and now on the web with CloudKit JS. With free public storage up to 1PB, it's never been easier to build and grow your apps using CloudKit.
Capacity scales with your users.
The amount of public storage and data transfer allocated to your apps will grow with every new active user—all for free with very high limits. Calculate the amount of storage you'll gain as your number of active users grows.
