What is ownCloud?

ownCloud Core is the server side of ownCloud Classic, a self-hosted platform for keeping files in sync across devices and sharing them with others. It provides WebDAV, CalDAV and CardDAV servers, user and group management, encryption support, external storage backends and a REST API. A plugin architecture lets apps such as Activity, Calendar and Contacts build on top of it. The server runs on PHP and works with MySQL, MariaDB, PostgreSQL or SQLite. ownCloud's newer platform, Infinite Scale (oCIS), lives in a separate repository.

Good fit if

  • You want to replace a hosted cloud drive with file sync and sharing on servers you control.
  • You already run a PHP and SQL stack and want to reuse it.
  • You need files, calendars and contacts served over standard DAV protocols.

Look elsewhere if

  • You would rather not depend on a vendor that is in the middle of relicensing its code: Nextcloud, also under AGPL.
  • You only need to keep folders in sync between devices without a central server: Syncthing.
  • You want files organized with custom properties, or one interface over several storage providers: Seafile or Cloudreve.

Before you adopt it

The code is licensed under AGPL, and the repository contains no paid parts, though the company sells enterprise support. Kiteworks acquired ownCloud in 2023, and its open source program office says it intends to relicense ownCloud repositories to Apache 2.0 once audits are done; this repository has not changed yet. Contributions need signed commits and a DCO sign-off. About 69 percent of recent commits come from one person, out of six authors. Installation follows the official manual; the README mentions a Docker Hub image, but the repository has no compose file.

Read from GitHub on 12 November 2026. How the score works

ownCloud security

Security advisories are the vulnerabilities the maintainers disclosed on GitHub, with the versions that fix them; many advisories can mean careful disclosure as much as weak code. OpenSSF Scorecard checks how a project is developed and released: reviews, protected branches, pinned dependencies, signed releases. It does not audit the code itself.
