Nextcloud Reviews 

Unreliable service on WebDAV. Deleted critical therapy data in syncing. I've switched to Dropbox for syncing mobile app data and intend to use Nextcloud only for backup and collaboration.

Sehr gute Cloud! Finde es super, dass man die Handy Bilder mit der App synchronisieren kann.

My experience so far - next is to delete the app and pick a trustworthy app and company

I have tested nextcloud as a self-hosted app - verdict do not go for it, unless you want to loose your local files for good

now I have decided to give it a go with IONOS ( super bad experiences so far) + Nextcloud, they offer managed Nextcloud installation on their Cloudservers.

So far my experience is zero star - the app is so buggy, all this open source things are risky... luckily I had redundant backup otherwise my work files would have been gone.

they have an App Store offering various app to extend the functionality of NextCloud - well most of the app there are developed by third-party "weekend developers" and they even dare to feature some of the app - one would think it is a sigil of a solid app, well it is not!

So far Nextcloud for me is next-in a hundred years-cloud. People I don't know what you think, the basic functionality of a cloud storage is an ironclad, solid, robust sync app - well yours is not definitely none of the above.

this is the thing with this open-source apps - seems like a cheaper option, at the end you end up paying the price of possible data-loss, nerve wrecking, and not even close production-ready environment.

End note: I am not a programmer / coder ... so that why I gave a 2nd chance with a managed Nextcloud via IONOS - well so far it makes no difference.
It is just ridiculous.

What the Nextcloud app perfectly delivers along with IONOS ist Nothing but disappointment, sleepless night hoping that all the files are synced, and not lost in space and annoyance pure beyond compare.

Very useful file hosting services, especially during the pandemic, it helps a lot to work from home.

Just love the fact that, I Own My Data. Also the price that's right it's free as in beer.

Nextcloud offers the world's best experience for self-hosting, as far as I have been able to research. Yes, you need to do some technical heavy-lifting, but there's a wealth of great advice out there.

All of their programming code is public, which means you can verify their claims for yourself (more importantly, so can the whole internet).

Go slow, there's a learning curve, but it can save you hundreds or thousands to provide your family with the same features of proprietary cloud providers.

Lost all my files on their Free 8 GB Nextcloud.

It's quite a shady company that I am not sure can really be trusted. I have exposed various issues over the years with Nextcloud which do not seem to be taken seriously.

rich plugin system so you can run web apps for everything from chat to mail.

Excellent product, and honest service.
