Cryptomator vs Boxcryptor opinions
FrankyWhiteUnfortunately, the Cryptomator apps (iOS & Android) are closed source but the rest is open source. The encryption is very good and user-friendly. It is perfect for home users.
3li0Cryptomator is a truly excellent application, I've been using it for local and cloud storage encryption and it is extremely useful. I recommend it to anyone looking to provide an extra layer of security to their cloud storage solution.
Opensource, mimics all functionality without license limitations.
JohnFastmanBoxcryptor is proprietary and costs money. Cryptomator is open source (you can check that it's implemented correctly) and it is free. Moreover, it works on Linux, which Boxcryptor does not. Cryptomator is excellent and basically a Boxcryptor killer. Mobile versions are in beta/soon ready.
Cryptomator does everything Boxcryptor does except it's free and open source, which means you can check the code for backdoors yourself, if you want. It also works on Linux, Mac and Windows. It makes encrypted copies of your files in a vault, which you can upload to, e.g. Dropbox, so that even Dropbox cannot see what you have in your files. Works with all cloud services.
Basically an open source clone of BoxCryptor

VeraCrypt vs Boxcryptor opinions
No file-per-file encryption
[TrueCrypt is not exactly "Open Source", but the source is available. See the reviews to get more information.]
Discontinued
Currently unmaintained. Last version, TrueCrypt 7.1a, is still available for download and development has continued via the forks
VeraCrypt and 
CipherShed. "The development of TrueCrypt was ended in 5/2014 after Microsoft terminated support of Windows XP. Windows 8/7/Vista and later offer integrated support for encrypted disks and virtual disk images."
TrueCrypt vs Boxcryptor opinions
TrueCrypt is still one of the best crypt tools out there, without backdoors and special general keys for authorities and the like.
DroidFS is an alternative way to use encrypted overlay filesystems on Android that uses its own internal file explorer instead of mounting virtual volumes. It currently only works with gocryptfs but support for CryFS could be added in the future.

CryptSync is a small utility that synchronizes two folders while encrypting the contents in one folder. That means one of the two folders has all files unencrypted (the files you work with) and the other folder has all the files encrypted.
Cryptsync vs Boxcryptor opinions
JohnFastmanDoes what Boxcryptor does. The advantages is that Cryptsync is open source, so you can have more confidence weaknesses will be spotted and fixed. The disadvantage is that Cryptsync is Windows-only. Crytomator is a good open source alternative that works on Windows, Mac and Linux. If you use Win only, Cryptsync is a good solution.
gocryptfs uses file-based encryption that is implemented as a mountable FUSE filesystem. Each file in gocryptfs is stored one corresponding encrypted file on the hard disk. The screenshot below shows a mounted gocryptfs filesystem (left) and the encrypted files (right).
