I've never personally used tarsnap so take everything I say with a grain of salt here. But Cryptic offers a much easier experience for the average user, being that it's entirely in-browser and not cli-based. We also give users the ability to share their files with others through the browser, which I don't think is as straightforward with tarsnap.

To play the devil's advocate, if you're already a happy user of tarsnap then you (like me, in fact) are probably quite comfortable on the command-line, and may even prefer it. As of right now Cryptic doesn't have a command-line utility, although building one is definitely on our radar! But until then you may find it more comfortable. Thanks for checking us out though!
