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.
Ever since I started using the Mountain Duck application I have loved it.
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.
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.
You have created a great tool. I use it every day and I cannot put into words how much this has helped me with my day-to-day tasks.
For those looking to mount an IaaS virtual drive, network-drive software works best, with Mountain Duck being our top pick.
