Pre-Built File System

CloudFS is a full‐featured file system, delivered through a powerful set of APIs that provides faster and more seamless integration to application layers than simple object stores provided by public clouds. Developers can leverage pre‐built files and folders along with upload, download, sync, and other media services. Sign up now.

Security & Encryption

CloudFS provides developers with the same private key encryption on top of AWS’s “11 9’s” infrastructure that Bitcasa uses for its Turn-key Drive and personal drive services, ensuring that the data stored in the applications and services you create is always kept safe and secure. Sign up now.

Data Ownership

Unlike other 3rd party cloud services APIs, CloudFS enables you to maintain ownership of your UX, your users, and their data. Using transparent authentication, applications talk directly to CloudFS via access tokens provided by your application server, with no end‐points to implement. Sign up now.

Free Prototyping

By setting up a free CloudFS account, you can develop and test your app before putting it into production. Use up to 25GBs of storage and 10,000 API calls a month to prototype your new storage feature, before upgrading to paid plans that include unlimited file size and end user accounts. Sign up now.
