Any idea how these guys make money?

You have to pay for the mobile apps.

They take donations. I've donated to get a "key" for my copy of Cryptomator, but it doesn't do anything to the software, it's just there to turn off the thing that asks you to donate, I believe. I use it as the primary way to encrypt sensitive documents before cloud syncing them, so I figured it was worth a donation.

gocryptfs is another option.

Love gocryptfs but it doesn't work well on Mac. securefs[1] works fine on both Linux & Mac.

do you know what advantages that has over rclone[1], which is much more popular?

I guess both securefs & gocryptfs are more tailored towards mounting encrypted folders locally (i.e. they don't have any support at all for cloud storage systems, that part is left to other tools).

But I guess you can do the same with rclone given that it supports encryption, mounting and the local filesystem.

I am not sure however how they compare in simultaneous read/write access by multiple users.

Depending on the use-case rclone's crypt remote might suit.

Another vote for rclone. Let's you easily turn any cloud storage service into one with E2EE encryption. And with 'rclone mount' you can get a network file system easily with decent performance and good local caching.

Also check out RCX if you're on Android.

Cryptomator works on iOS devices, rclone does not :)

Naive question: Why is this a reason to switch?

Boxcryptor clients (client software) probably will stop being updated sometime in the foreseeable future, which at least for mobile will make Boxcryptor nonviable, even in the accountless mode.

Unfortunately Cryptomator isn’t as reliable as Boxcryptor.

I have not had this experience. I switched to Cryptomator because it was a much smoother and more reliable experience for my use cases. What issues did you have?

Just today I was lamenting the lack of Document Provider APIs on Cryptomator Android, I'd like to use it to encrypt my Obsidian vault. Alas the issue is locked and the milestone keeps shifting.

Cryptomator has been good to me otherwise!

This really is the dealbreaker for me, I bought the android version, but it's pretty useless without the document provider

Any hints on setting up remote server? What service should be used for file uploads, that wouldn't require much maintenance and be stable?

Does cryptomator only work with Dropbox?

No. It's works with most cloud storage, either with their own client or cyber duck/mountain duck.
