An ownCloud Classic (OC10) app that enables sharing files with external users via email address. When a file is shared with a guest, they receive an email invitation with a link to create an account. Guest users have access only to files shared with them and can use a configurable whitelist of allowed apps (such as file viewers, text editors, and activity tracking).
Enable the app in the ownCloud admin panel:
sudo -u www-data php occ app:enable guestsTo invite a guest, type their email address in the sharing dialog. The guest receives an email with instructions to create an account. Administrators can configure the allowed apps for guest users in the admin settings.
This app extends ownCloud Server with guest user capabilities. It is shipped as part of the ownCloud Server Docker image.

The Kiteworks Open Source Program Office, operating under the ownCloud brand, launched on May 5, 2026, to steward the open source ecosystem around ownCloud's products. The OSPO ensures transparent governance, license compliance, community health, and sustainable collaboration between the open source community and Kiteworks, which acquired ownCloud in 2023.

For questions about the OSPO or licensing, contact ospo@kiteworks.com.
The OSPO is driving a strategic relicensing of ownCloud repositories toward the Apache License 2.0, following the Apache Software Foundation's third-party license policy.
Individual repositories will migrate as their audit is completed. The LICENSE file in each repo reflects its current license status (not the target).
Current license: GPL-2.0 (Category X per Apache policy -- cannot be included in Apache-2.0 works).
Migration prerequisites for this repository:
- CLA/DCO coverage: All past contributors must have signed agreements permitting relicensing
- Copyleft dependency audit: All GPL dependencies must be replaced or isolated
- KDE heritage review: Any code with KDE-era copyrights requires legal analysis
- Complete relicensing: GPL-2.0 is a strong copyleft license; migration requires full relicensing of all files
