As a web design company, we work with several clients and use OwnCloud to store and transfer design assets and large files. We use lots of photography and OwnCloud has the capacity to store these files for safe keeping.
  • OwnCloud has a nice filing system where users can create lots of different folders and subfolders to help keep things organized.
  • OwnCloud has lots of space depending on your plan and it's great for holding files and storing things you wouldn't want to take up space on your desktop or an external hard drive.
  • The more files OwnCloud has, the slower it seems to be. Viewing files inside OwnCloud can be really cumbersome and I have found other tools to be much more user friendly in finding what I'm looking for.
  • Viewing photography assets stored in OwnCloud is extremely slow and not as helpful as something like Google Drive or even Dropbox would be.
It's well suited if you are storing lots of files for a project and want to keep things organized by multiple projects. It's also nice because you can package up links and send them to clients without them having to have an account.

In our research group, we used ownCloud for cloud services such as file syncing as well as file sharing—even large files—with others members of the team. It allows us to store files and share them among different people and have our own individual folders. We don't need to worry about forgetting files, because we can always reach out over the net to retrieve them.
  • Open plaform, one can federate with others' OwnCloud and share files.
  • Easy to upload and download documents.
  • Scalable and lightweight solution for cloud storing.
  • The Web user interface can be a little be slow sometimes.
  • No online video viewer by default.
  • No online document editor.
I'd easily recommend ownCloud to small businesses or teams within organizations. I've not used ownCloud in large deployments, so I'd hesitate before suggesting it in a situation where more than 10 users need support. That said, ownCloud is easy to set up and multiple instances could be used to service a large user base.

We use ownCloud in the export department of the organization to exchange files with our customers. Some users use it for their personal cloud to work from with all their files and media 100% in the cloud. It solves quick and painless file exchange with no password issues. The links can be set to expire after a certain time.
All data is on our own servers, we don't have to be afraid of misuse of our information/industrial espionage, etc. we are 100% in control of our own data.
  • 100% of our data is stored ONLY on our servers and workstation. No external hosting anywhere.
  • Open source, no recurring fees for any amount of data we need.
  • Feature rich browser based application.
  • Mature desktop sync client for PC and Mac.
  • The iOS app is sometimes slow or hangs
  • The sync conflicts are displayed in detail in the client application, but you have to resolve manually
+ Excellent for a personal or small business file server
+ Collaboration server
+ Replacing Exchange server with WebDav Calendar sharing and Contact Sharing
- Easier integration for WebDav in Outlook, you have to do some research on your own

I currently use ownCloud for cloud services such as file syncing, centralized calendar and contacts, as well as file sharing—even large files—with others. As an IT contractor, ownCloud has been great for enabling my access to business information anywhere I have access to the Internet (with limited functionality offline as well). I'm able to use my mobile device so I can schedule events that appear on my phone's calendar, as well as on my desktop/laptop machines. I don't need to worry about forgetting files, because I can always reach out over the net to retrieve them. If I save files on my laptop while with a client, I can access them on my office computer effortlessly. ownCloud is an elegant solution for much of my vital digital resources.
  • File Synchronization
  • Synchronized Contacts
  • Synchronized Calendar
  • File Sharing
  • Online Document Editor (new feature)
  • Web Media Player (new feature)

I own a computer service and support company, and I also own a Photography business. OwnCloud -- now NextCloud -- has been an indispensable suite of applications that has allowed me to continue to serve my customers on both business fronts, and has allowed me to grow my business by being able to offer real-time sync and file shares as needed. I absolutely love ownCloud, and am very grateful that this project exists.
OwnCloud has enabled me to increase my services and my offerings, therefore increasing my bottom line without substantial cost increases and without monthly subscription charges. In my opinion, there are more features and more value in ownCloud than there are on paid cloud storage/collaboration platforms.
  • Attention and dedication to making the product a world class product with continual product updates.
  • Ease of use from an administration standpoint, and a very Clear UI.
  • The price -- you can't beat free!
  • Mobile applications are great.
  • Integration with public S3 cloud providers like AWS S3 and Wasabi S3.
  • 2FA authentication is supported and works great!
  • Marketplace Add-Ons: I love this! For example, I can install an add-on that natively opens raw images. I am a photographer as well, and being able to quickly view the CR2 Raw Files direct from the camera is fantastic! This was made possible by a marketplace add-in.
  • Embedded Media Players: Photos, Music, and Video files can be viewed and played right in the browser window.
  • Sync application to keep local files on a computer updated with the files on the server.
  • Access control and permissions -- shareable links!
  • Backup and redundancy -- I wish there was a method right in the interface to completely back up the entire system. I use it on a VM, so I can snapshot and backup the VM, but there is nothing directly in the ownCloud interface to be able to do.
  • Docker/Container/MVM Function. I would love to see ownCloud natively support docker or virtualizations where it could host and spin up a VM or run containerized applications.
OwnCloud/Nextcloud is a great application for cloud storage of files, and makes sharing specific files or folders easy and fast. It also makes a great tool for real-time collaboration, including real-time chat and simultaneous editing of documents or spreadsheets. I have used ownCloud to assist clients in sending large files that could not be emailed -- for example, one of my clients is a Video Production agency. They produced a commercial to air, but could not email the file as it was 400MB. OwncCloud came to the rescue. I set up a temporary share and allowed him access to upload into that folder. Once the file was in the folder, I generated a share link that was then forwarded to TV stations for instant viewing in a browser. Each TV station then downloaded it and was able to add it to their scheduling system quickly.
From the Photography side... I am able to deliver large amounts of files quickly and easily to my clients, and they can download or view on mobile devices easily.
Since I use ownCloud on a daily basis, I cannot think of any reason why I would not use this software.

I use it to store my personal files as the free solutions (Gdrive and such) do not offer enough storage.

We do not use it inside the organization but I think ownCloud would be a great fit for small to medium enterprise as it offers enterprise features and it's really simple to set up and operates. Of course, the main problem is that you need to host it but there is a lot of cloud-hosted instances of ownCloud that can be worth it IMO.
  • Great sync apps on Windows, macOS, Android, and iOS. (was even better then gDrive client for a while but they caught up)
  • A lot of Security features including End-to-End encryption, server-side encryption
  • Control on where your data is stored
  • Plugin marketplace allows for unlimited features
  • Incomparable transfer speed if hosted locally
  • Always has the latest feature because it's open source
  • Expiration date/timer on sharing (either to someone directly or on links)
  • Requires you to manage the infrastructure, software updates, backups and security because it is self-hosted
  • The picture viewer in ownCloud is not really snappy by default (You need to setup plugins or some kind of cache)
  • No video viewer by default
  • The web UI requires a cache setup to have reasonable load times (to be fair, it is recommended in the admin page)
  • I stopped using the calendar and contacts plugins because after each update they would break
OwnCloud is a great replacement to local SMB shares, in my opinion. It supports Webdav and it can be easily and safely published on the internet for remote access to the data without VPN. OwnCloud would also be great for a small to medium enterprise that can't afford the real enterprise alternatives, need way too much storage or need/want to control where their data is stored. I don't think ownCloud is well suited for big enterprises unless you really need to control/secure your data. I feel it would need a lot of investment to scale on a large user and data scale and stay responsive.

I use OwnCloud for my personal documents. I want to keep my data and the corporate data on a separate system since there is no reason to use expensive corporate resources for my own.

With OwnCloud, I have the exact same enterprise level feature that we have with the corporate system but for my own personal needs.

I share documents and folders with my friends and family, browse my online pictures, listen to music, edit documents, in a very secure manner.
  • Many plugins, for video, audio, documents, integrations, etc.
  • Very secure, including end-user file encryption.
  • Open, I can federate with my friends' OwnCloud and share/backup documents.
  • You host your own data, maybe it's better to use an hosted version of OwnCloud to keep the files at a different location.
  • The WebUI can be very slow sometimes.
If you want to keep control of your files, for yourself or for your company, OwnCloud is the self-hosted cloud for you. There is no real competition when it's time for self-hosting. If you are looking for a hosted version, be sure to compare with the big players like Dropbox, Google and Microsoft. It's cheap, highly available, and secure.

OwnCloud is used as a way to upload, managed, and access documents across the district, especially when we are not in the same building. It is used across our organization and also used in our department.
  • Easy to upload and download documents
  • Easy and efficient to use
  • Easy to organize
  • I haven’t come across many issues.
I have a giant Excel spreadsheet and a Notebook document I use to upload for someone else to look at. They are able to download and look at it as if we were sharing the same screen. I appreciate being able to upload large documents and not having to send it through an email in a compressed or Zip file.

We use ownCloud across the whole organization. We manage file sharing in a secure way with employees, partners, and customers through our private cloud infrastructure. We have implemented our own ownCloud Solution based on an appliances format, so we can deploy ownCloud in a few minutes with enhanced features developed by ourselves. The information from several sources is replicated to the exact folder of ownCloud so it is available in real time by the suitable people with the suitable permissions.
  • Easy to deploy
  • Easy to manage
  • Cost-effective
I believe that ownCloud is suitable for any kind of company for normal file synchronization and file sharing. It is less recommended for companies that use very large files based on images.

We use it in the whole organization as the main document server. All employees including the management have the ownCloud desktop sync apps installed. Virtual users own different main folders (e.g. SALES, FINANCE etc.) and these are shared to groups read-only, read-write. Each user gets, therefore, a different set of folders according to the needs of each employee etc. Some people use it on a mobile, too.

It solves the key problem the company had when I joined it and no document server/cloud storage was present: each of the at-the-time few employees had its own set of files and folders and data were exchanged only via emails. Another important aspect is auto-backup of all company data to remote server. Easier collaboration on documents is also important.
  • Runs fine on a inexpensive Linux VPS with a few CPU cores and little RAM and is able to serve well for dozens of users. The scalability at almost no extra cost is perfect.
  • Sync clients are available for all major platforms: MS Windows, Mac OS X, GNU/Linux, and mobile apps on Android and iOS are available too and work very well. We use all these platforms and are able to exchange documents transparently.
  • Initial setting up the environment for users - such as creating a few user groups, virtual users owning particular folders and assigning users to these groups, is quite easy and quick. Auto-sync of data to local devices on all platforms is also perfect, users don't have to manually select anything, default is to sync (or admin can set on the desktop clients how big folders are auto-synced).
  • Inability to easily collaboratively edit the same document by several people. Some advances have been made with Collabora (LibreOffice online) but it is still very sub-par compared to Office365 and desktop/online Office editing Sharepoint or OneDrive documents.
  • Apps for Calendar and Contacts are not part of the basic core, and although now quite supported they cannot still be easily deployed in common email clients such as Outlook or Thunderbird, separate CalDAV and CardDAV plugins need to be installed. Embedding an email solution and plugins for major email clients so they can work just by entering username and password would be good.
  • Risk of moving important folders/files to another location just by random drag-and-drop on Windows. Sometimes this breaks public links that cannot be restored anymore. Reverting such mistake by any of the users is impossible automatically.
  • When some user deletes some data in a shared folder it is put into recycle bin of the owner of the folder. The user who deleted cannot himself/herself revert such action as he/she does not see the recycle bin (trash) of the owner. Also, there is no log in the recycle bin who deleted that file or folder.
Perfect for a smaller company having no solid document server. Without any major costs you can go from 3 to 30 to 60 users with the same hardware or VPS and if self-managed, no payment per user per month. Less appropriate when users absolutely require collaborative editing of documents. Pick Office365 or G Suite (Google Documents for work) instead.

We use OwnCloud to share work with clients. Before this we were using WeTransfer, but the issue is you can't go back and look at files.

Using OwnCloud meant we could host the files on our own server, therefore having full control over the usage, and then we could just simply set up users for clients and then files are just shared in their own folder within OwnCloud.

Owncloud also allows sharable links, so clients can easily send downloads to us through there.
  • File Sharing - getting sharable URL of a file for quick access
  • Users - we can make clients their own accounts so they can store their own files
  • Security - Its really nice knowing the files are hosted on our server, as we know it's secure!
  • I think the UI is a little outdated now
  • The usage on our server seemed quite large compared to others
  • I think adding a built in file editor would be super useful
It's perfectly suited for agencies, where customers and clients are constantly sharing files with each other. Owncloud allows for this, and it's really easy to go back and see what files were shared and when! Having an archive is really useful as we don't have to go back to the client and request it again!

ownCloud is currently used as an access point for mobile users to connect with the corporate office.
  • Fast access times
  • Easily managed
  • Scalability
  • Newest releases not supported in updated Ubuntu servers
  • Major issues connecting with Windows server shares on any version past 8.1
  • Unreliable admin user password resets
Easy to setup and maintain on linux systems but lacks usability if used in a Windows server environment when SMB shares need to be mapped.

We use ownCloud to share docs within the organization as well as with outside vendors and consultants. It addresses the problem of sending larger docs to other team members in a way that is easy to access and download.
  • Ability to share docs with others. You can email a link, and share with people outside the company.
  • Share directly to another person's account within the company.
  • Creating folders of docs and ability to share is helpful.
  • It would be VERY helpful if there were a way to share videos without the other person having to download them.
  • It would be nice if a person can view docs without having to download them.
ownCloud is well suited for a company that needs to share many docs with one another.
