What is Nextcloud?
You should have full control over your data. We help you achieve that: a safe home for all your data. Secure, under your control and developed in an open, transparent and trustworthy way. We are Nextcloud.
Nextcloud offers industry-leading on-premises file sync and online collaboration technology. Our expertise is in combining the convenience and ease of use of consumer-grade solutions like Dropbox and Google Drive with the security, privacy and control business needs.
Our self-hosted solutions ensure you know where data is, who has access, and that even meta-data does not leak.
We create three products, integrated and acting as one:
Nextcloud Files offers an on-premise Universal File Access and sync platform with powerful collaboration capabilities and desktop, mobile and web interfaces.
Nextcloud Talk delivers on-premises, private audio/video conferencing and text chat through browser and mobile interfaces with integrated screen sharing and SIP integration.
Nextcloud Groupware integrates Calendar, Contacts, Mail and other productivity features to help teams get their work done faster and easier.
Our products integrate powerful capabilities to control and monitor data exchange and communication, including our unique File Access Control and workflow features, extensive audit logs, fine-grained sharing controls and more.
Security is Nextcloud users' greatest concerns and our prime advantage over competitors. Nextcloud features a host of unique, innovative security technologies from brute force protection to advanced server side and integrated end-to-end, client side encryption with enterprise-grade key handling and a wide range of security hardenings. Our security has been reviewed by trusted third parties and is backed by a USD 5000 Security Bug Bounty Program, providing the confidence that data meant to stay private will stay private.

I love open source software, and in the story of NextCloud and its OwnCloud roots, I side - overall - with NextCloud. For reasons of freedom and openness and trying to make the world a better software place. But... I won't use NextCloud in the near future and the reason is that my needs aren't met by the NextCloud client. It seeks to allow me to sync my files between multiple computers. But I have - literally - hundreds of thousands of (very small, ie <100kB) files to sync. And the NextCloud client can't cope with this. It tries to catalogue everything and gets stuck, lags, and mashes up the sync. That was the case with OpenCloud's v9 client and it's true of NextCloud v11.
I love the idea of NextCloud, but it doesn't work for me.
If you're not a special case like me, try it; I think it might be worth your while, so you can escape the tyrrany of evil services like Dropbox and Google Drive, who have your number, can read your files and must give it to the NSA if asked without telling you.
Otherwise, spare a thought for the low price, reliable and EU-based seafile.de (now SyncWerk.com).
Yes, syncing hundreds of thousands of very small files is a though challenge and the current client isn't super good at it. However, we have made progress already and are working on a more complete solution - be sure to check it out again in half a year or so ;-)

The best solution for my private cloud: more configurable and stable than others. The best for help make my docs really privates!
Nextcloud works without a flaw, havent found a single bug or con. But I would only recommend installing it through TrueNAS Scale because its only minor downside is that its a pain in the ass to install on bare metal linux distro or VM, just go with TrueNAS it is basicly intergrated and super easy, 1 click away. 10/10 and it's 100% free!
it makes you feel like owning a corporation just by installing it on a raspberry pi
wait a minute, wait a minute, it is not all milk and honey. But nothing is and the ones that know what upkeep means will understand me. Nextcloud has all the advantages: you own your data and you have access to it in multiple ways. It enables collaboration and its set of features is constantly expanding. What Nextcloud does not have? Well it is actually what you do not have: you will need time and skills for the set up and for the upkeep. This is for the case when you want to self host. Or you can opt for having it in the cloud and let, for a fee, somebody else manage it for you. Like for example the Hetzner Storage Share. Its not as easy as Google Drive, Dropbox or Onedrive, but you own the data, you know where is stored and how and who is accessing it.
absolutely useful
Nextcloud rocks. The AIO Docker image makes installation a breeze. I just wish they fixed end-to-end encryption. Apparently that has been broken since it's release a couple of years back.
