I use it specifically to keep my files out of the cloud, but in the past I've also installed it on a DigitalOcean instance and had it function sort of like cloud storage that way.
My favorite thing about it is that you're selecting existing local folders to sync rather than moving files to a special "sync" directory, meaning it's very flexible in what you can do with it (syncing dot files between machines, as one example).
The only problem is there's no good iOS client yet, but macOS, Windows, Linux, Android are all supported.
The only thing we miss is shared doc editing but we only really used that intensively a couple of times so we didn't miss it much.
The desktop integration is pretty good. The one advantage Dropbox would have had is LAN syncing, but as we mostly work remotely this isn't a big issue.
It's not a backup solution, but rather an archive. With backups, you might expect files to be synced after changes, which my app won't do. Rather as an archive, you can just drag n' drop the files/folders you want to archive and it'll be moved to cloud storage and then you can delete the local copy of those files on your computer.
The files in this archive storage are also not meant to be shared like Dropbox or Google Drive because it's supposed to be your personal archive of files/folders, so there's no sharing functionality.
If that fits you what you are looking for, do give it a try.
A use case I had was that my Mac was running out of hard disk space and I didn't want to carry around an external hard drive or get a new Mac, just for more disk space. I tried cleaning out as much unused applications and files as I could, but there still remained large and old files that I wanted to preserve to keep a record of them.
Moving it to cloud storage for archival gets me the long-term storage and by deleting the local copies of it, I was able to get back a good chunk of space on my Mac. Not everyone may have this use case, but it was one I came across where deleting the local copy made sense.
The server was very straightforward to set up on a DO droplet. They even have an install guide for Seafile on Ubuntu 18.04

It makes it nice because I can still access all my files using the selective sync feature and if I am moving between computers, I can drop anything in those specific folders and have access to them on any computer running Resilio. As well as be confident that it will be backed up and encrypted.
If you don’t upload a lot of big files often and can deal with their restrictions for characters in file names it’s a great solution for 98% of people.
Dropbox is fabulous but expensive. If you’re a Mac person and don’t need to share folders, iCloud is much better these days as well — my spouse uses that.
Rolling your own seems like a more expensive path more likely to lead to disaster.
i have other repos stored for free in private github or bitbucket accounts, but i prefer to be a paying customer for storing some things that i feel are more critical.
edit: it looks like aws code commit storage costs are 0.06 $ gb^{-1} month^{-1} -- about 10x the cost of the wasabi storage mentioned elsewhere in this discussion. but the first 50 gb month^{-1} is free.
It's definitely cheaper for archiving files, but there are some catches like minimum file size and storage duration costs, but still overall cheaper than the other storage solutions I've come across.
