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.
Thanks so much for the application! It’s really brilliant, definitely will make web development much simpler!
Thanks works like a charm so far!
All I can say is - it works and I love it, it is simple, small, unobtrusive and hassle-free.
Many thanks, this is a great application. The integration with the finder makes working with FTP servers a lot more seamless. I love it!
I've been using Mountain Duck without issues for weeks now. It's massively useful.
Ever since I started using the Mountain Duck application I have loved it.
