The best apps for cloud storage on a Mac
By Vishva Variya · Updated
Short answer
To mount clouds and servers without their sync apps, CloudMounter ($74 lifetime or $29 a year), ExpanDrive (free for personal use) and Mountain Duck (with Cryptomator encryption) are the main picks. ForkLift and Commander One add clouds to a dual-pane file manager. If Google Drive, Dropbox and OneDrive already sync on your Mac, Peekaboo puts them in one sidebar and one search.
How we picked. Prices and macOS requirements come from each vendor’s own site or Mac App Store listing, checked between November 2 and 7, 2026. Each app is listed for the job it does best, not ranked overall. Peekaboo is our app; it’s listed with its gaps, like the others.
Before you buy anything: Finder (built in)
Free, and the providers’ own apps put Google Drive, Dropbox and OneDrive under Locations in its sidebar. Each drive stays separate, there’s no one search across them, and Finder doesn’t show at a glance which files take space locally.

CloudMounter: Many clouds as Finder drives, no sync apps
Mounts Google Drive, Dropbox, OneDrive, S3, FTP and more as drives in Finder, without their sync apps.
- Cloud accounts mounted as Finder drives, several per service
- Drag files from one cloud to another
- S3, Backblaze, MEGA, pCloud, WebDAV, SFTP and FTP alongside the big three
Gaps: Lifetime licences are for personal use on one Mac, and the 7-day trial applies to the yearly plans only.

ExpanDrive: S3, SharePoint and servers, free for personal use
Streams S3, Google Drive, Dropbox, OneDrive, SharePoint and SFTP into Finder on demand, free for personal use.
- Files streamed on demand, with an offline cache you can pin
- Built on Apple’s File Provider: no kernel extension or reboot
- A scriptable command-line tool and Spotlight on mounted files
Gaps: Free is for personal use only; teams pay a monthly Business fee.

Mountain Duck: Servers and encrypted cloud storage
Mounts servers and cloud storage as disks, with Cryptomator encryption and files you can pin for offline work.
- Client-side encryption with Cryptomator vaults
- Smart Synchronization: pin folders to keep them offline
- FTP, SFTP, WebDAV, SMB, S3, Azure, SharePoint and the big clouds
Gaps: A direct licence covers one major version, so a new major version is a paid upgrade; the App Store edition is a subscription.

Peekaboo: One search across the drives you already sync
Finds the Google Drive, Dropbox, OneDrive, Box and iCloud Drive folders your providers’ apps already sync and shows them in one sidebar and one search, with what’s downloaded and what’s cloud-only.
- Nothing to sign in to; no cloud passwords reach the app
- Plain-English search across every drive and the Mac
- Remove Download and Download Now, with cloud files kept out of Clean Up
Gaps: It doesn’t connect to clouds itself: no S3, SFTP or WebDAV, no moving files between clouds, and it needs each provider’s app installed.

- Git status and commit from the file list
Gaps: Licences are lifetime but include only one or two years of updates, and ForkLift 4 needs macOS 14.6 or later.

Questions
Can I use Google Drive, Dropbox and OneDrive in one app on Mac?
- Yes. CloudMounter, ExpanDrive and Mountain Duck connect to all three themselves. If their own apps are already installed, Peekaboo shows all of them together in one sidebar and one search.
Is there a free app to mount cloud storage on Mac?
- ExpanDrive lists a free plan for personal use, as of November 7, 2026. Mountain Duck and CloudMounter offer trials.
Which option encrypts files before upload?
- Mountain Duck, through Cryptomator vaults. The others here don’t list client-side encryption on their own sites.
