Mountain Duck alternative: Peekaboo vs Mountain Duck
By Vishva Variya · Updated
Mountain Duck, from the makers of Cyberduck, mounts servers and cloud storage (FTP, SFTP, WebDAV, SMB, S3, Azure, SharePoint, Google Drive, Dropbox, OneDrive and more) as disks on your Mac, with Cryptomator vaults for client-side encryption and folders you can pin to work offline. Peekaboo doesn’t connect to anything: it finds the cloud drives your providers’ apps already sync and makes them part of one library, one search and one picture of your disk.

Why pick Peekaboo over Mountain Duck?
Servers and encryption are Mountain Duck’s
If you work on SFTP or SMB servers, or want files encrypted before they leave your Mac, Mountain Duck is built for that and Peekaboo has no equivalent.
Finding across drives is Peekaboo’s
Plain-English search covers every cloud drive with the rest of your files: “pdfs from last week in Dropbox” works the same as anywhere else on the Mac.
Local space you can see
Each file shows whether it’s downloaded or only in the cloud, and Remove Download frees the copy without touching the file in the cloud.

The honest verdict
Mountain Duck is the better pick for servers, S3 and encrypted cloud storage, and Peekaboo doesn’t compete there. If what you want is one place to see and search the Google Drive, Dropbox and OneDrive folders you already sync, and to free their downloads safely, Peekaboo does that with the rest of your Mac.
