Mountain Duck lets you mount server and cloud storage as a disk on your desktop. With Smart Synchronization, files are synchronized to the local disk when opened to allow offline usage and changes are uploaded in the background as soon as a connection is available. Open remote files with any application and work like on a local volume. Transfer files using Finder to remote servers, fast. Select files and folders to always keep offline on your computer. Other files are downloaded and cached on demand only and otherwise do not take space on your local disk. Encryption for data at rest using Cryptomator interoperable vaults prevent unauthorized access regardless of the server or cloud storage infrastructure.
Based on the solid open source foundation of Cyberduck, all major protocols are supported to connect to just about any server you want. Including FTP, SFTP, WebDAV, Azure Cloud Storage, Amazon S3, Google Cloud Storage, Google Drive, Dropbox, Backblaze B2 & OpenStack Swift.

I really wanted to like this software

I needed an SFTP connection to dev servers for Agentic OP integration for dev work. Day 1 seemed OK. Day 2 I came back to my workstation where the system was “active all night” Mountain Duck didn’t let my system go to sleep. During Day 2 I was then frought with multiple disconnects as the Agent was trying to parse files. Script failure galore. This was on a Local Area Network so there were no “Internet Connections” to be concerned. The process decided to consume 100 to 300% CPU on an M4 Mac. This doesn’t seem right for a minimal MAC install. I’ve read where Gigs of data processing can cause problems, yes.. this was a small Website with JS manipulation where the total site was less than 5MB. Finder integration was sketchy and there was no rebound from trying to kill the process manually.. a reboot was required. I don’t write this as a complaint. I write this as information as I hope the developer takes this feedback as useful information to hopefully make his product better. For now I will be finding a different solution for my needs. I can’t continue troubleshooting an issue not related to the agent and I need a reliable solution for direct SFTP connectivity
Like many other cloud mounting apps, this one has issues

Copying files from S3 to Dropbox actually worked quite well. However, I see the disks randomly disconnect, fail to refresh, and just exhibit behavior that makes it generally unusable for anything other than bulk, on-demand tasks.If you plan on mounting some remote storage (SFTP) to work with an IDE to do development this is probably not a good choice.Also, I've run into the application hanging when trying to remove files with "rm" via the terminal from S3. There didn't seem to be a way to get the command to exit, even with CTRL-C, but the file did actually delete.
One of the best

Extends my desktop to servers, sharepoint, S3 and more, reliably. But don't expect the attached disk to work exactly like your internal disk - it's a long way away! When you take that into consideration then this is one of the best tools out there.Making an S3 bucket or a SharePoint or Google drive look like a local disk is no easy task. Things you do on a local disk like renaming files, moving a hundred files to a new folder, etc. become far more difficult when the wire between you and the disk is 2,000 miles long!Take S3 for example, you can't rename or edit files in an S3 bucket yet Mountain Duck makes it seem as though you can - silently re-copying and renaming S3 objects in the background - more like a swan than a duck.
Fantastic - S3 As a Filesystem More

I love this application. I was previously on the G Suite plan with unlimited storage, but when that was phased out I needed a solution to let me have multi-system sync and offline access to large collections of data. Mountain Duck lets me do this; and with a combination of being able to use native AWS S3 and local S3 I can mix and match my storage tiers and pricing!One request here -- would be great if we could enter our own preferences on the sizes of the local cache. The existing choices jump from 10 GB (not enough for some workflows) to 500 GB (more local disk than I have). Can we just enter a number in GB?
