ownCloud is a suite of client–server software for creating and using file hosting services. ownCloud functionally has similarities to the widely used Dropbox. The primary functional difference between ownCloud and Dropbox is that ownCloud does not offer data centre capacity to host stored files. The Server Edition of ownCloud is free and open-source, thereby allowing anyone to install and operate it without charge on their own private server.
ownCloud supports extensions that allow it to work like Google Drive, with online document editing, calendar and contact synchronization, and more. Its openness avoids enforced quotas on storage space or the number of connected clients, instead having hard limits (like on storage space or number of users) defined only by the physical capabilities of the server.
The development of ownCloud was announced in January 2010, in order to provide a free software replacement to proprietary storage service providers. The company was founded in 2011 and forked the code away from KDE to github.
ownCloud Inc., the company founded by Markus Rex, Holger Dyroff and Frank Karlitschek, has attracted funding from investors, including an injection of 6.3 million US$ in 2014.
In April 2016 Karlitschek left ownCloud Inc. and founded a new Company and Project called Nextcloud in June 2016, resulting in the closure of ownCloud's U.S. operations. Some former ownCloud Inc. developers left ownCloud to form the fork with Karlitschek.
In July 2016 ownCloud GmbH, based in Nuremberg Germany, secured additional financing, and expanded its management team.
In October 2018, for the 3rd time in a row, ownCloud GmbH received the IT Awards, which is based on the vote of over 30,000 business users for their best of choice Enterprise File Sync and Share solution.
In March 2019, ownCloud launched the BayernBox in cooperation with the Bavarian State Office for Survey and Geoinformation, an ownCloud-based collaboration solution for the bavarian municipalities. The deployment involves one ownCloud instance for each of the over 2000 municipalities.
To bring the architecture of the iOS app up-to-date with the state of technology, in June 2019 ownCloud released a complete rewrite of its iOS app. It had a strong focus on security and made use of many iOS integration features for improved usability. Contrary to the old app, it was released free of charge.

For desktop machines to synchronize files with their ownCloud server, desktop clients are available for PCs running Windows, macOS, FreeBSD or Linux. Mobile clients exist for iOS and Android devices. Files and other data (such as calendars, contacts or bookmarks) can also be accessed, managed, and uploaded using a web browser without any additional software. Any updates to the file system are pushed to all computers and mobile devices connected to a user's account.
owncloud is a software only product. owncloud does not offer off-premises storage capacity. This is in contrast to the likes of Dropbox that offers both software and off-premises storage capacity. owncloud storage capacity has to be provided on user owned devices.
ownCloud files are stored in conventional directory structures, and can be accessed via WebDAV if necessary. User files are encrypted both at rest and during transit. ownCloud can synchronise with local clients running Windows (Windows XP, Vista, 7 and 8), macOS (10.6 or later), or various Linux distributions.
From the administration perspective, ownCloud permits user and group administration (via OpenID or LDAP). Content can be shared by defining granular read/write permissions between users and/or groups. Alternatively, ownCloud users can create public URLs when sharing files. Logging of file-related actions is available in the Enterprise and Education service offerings.
Furthermore, users can interact with the browser-based ODF-format word processor, bookmarking service, URL shortening suite, gallery, RSS feed reader and document viewer tools from within ownCloud. For additional extensibility, ownCloud can be augmented with "one-click" applications and connection to Dropbox, Google Drive and Amazon S3.
All ownCloud clients (Desktop, iOS, Android) support the OAuth 2 standard for Client Authentication.
For Enterprise customers, ownCloud GmbH offers apps with additional functionality. They are mainly useful for large organizations with more than 500 users. An Enterprise subscription includes support services.
ownCloud server and clients may be downloaded from the ownCloud website and from third-party repositories, such as Google Play and Apple iTunes, and repositories maintained by Linux distributions. In 2014, a dispute arose between ownCloud and Ubuntu regarding the latter allegedly neglecting maintenance of packages, resulting in the temporary removal of ownCloud from the Ubuntu repository.
ownCloud has been integrated with the GNOME desktop. Additional projects that use or link to ownCloud include a Raspberry Pi project to create a cloud storage system using the Raspberry Pi's small, low-energy form-factor.
