Testimonials

We have had a long private beta period with intensive testing 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

Thanks so much for the application! It’s really brilliant, definitely will make web development much simpler!

Bobby Dilley

Thanks works like a charm so far!

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!
