Why CloudMounter

Besides its support of numerous protocols and cloud services, CloudMounter is also an ultimately safe and handy utility. The app works directly with Mac OS X Finder and Windows Explorer for the most convenient management of your files. You won't have to worry about safety of your personal information. More cloud services will be supported in the future.

Keychain support

CloudMounter does not use, store or send your personal information to any 3rd party resources. All your passwords are securely kept in Mac OS X keychain and sent directly to the servers via encrypted channels.

Finder and Explorer Integration

CloudMounter is basically a connections manager that lets you mount different cloud services and web servers on your Mac or PC as local disks. It serves as a connector between your computer and remote servers, integrating online resources directly to the native file manager.

More Cloud services

CloudMounter is not a finished project. We are constantly looking to improve and add support for other cloud services and more connection protocols. In the nearest future we hope to offer full integration with iCloud and several other cloud storages.

All supported services

CloudMounter works great with Amazon S3 storage and supports multiple cloud services.

    I’ve regularly used ExpanDrive and the native Mac client from Google, until recently. CloudMounter is simply the best of both worlds.
