Testimonials

We are dedicated to make Mountain Duck work well and fast. This is what our private beta testers have been saying.

This weekend I accidentally stumbled on mounting my entire vagrant disk over FTP using Mountain Duck and it’s been jaw-dropping amazing.
Michael Weigle

Bram Hilgersom

All I can say is - it works and I love it, it is simple, small, unobtrusive and hassle-free.
Rok Lipnik

Ever since I started using the Mountain Duck application I have loved it.
William Andersen Jr.

The reliability and stability of the transfers keeps getting better and better. With high-speed home internet, remove storage such as Wasabi, Google Drive, etc. makes total sense. Mountain Duck allows those to appear as reliable local storage.
Michael Thwaite

Many thanks, this is a great application. The integration with the finder makes working with FTP servers a lot more seamless. I love it!
Christian Von Alten
