ownCloud
Verified working Sep 21, 2026
Self-hosted file sharing for teams that need data control.
ownCloud is an open-source file sync, sharing, and collaboration platform for organizations that want to keep control over where files are stored. It supports private, on-premises, data-center, hybrid, and hosted setups, with access controls, secure sharing links, lifecycle management, and integrations for online document editing.
Why it stands out
- Can be deployed on-premises, in a chosen data center, as hybrid infrastructure, or as a German-hosted SaaS option.
- Built around data sovereignty rather than forcing files into a generic public cloud.
- Large existing user base and long-running open-source ecosystem.
- Office collaboration is modular, with support for multiple document-editing backends instead of one locked-in suite.
- Infinite Scale separates storage, backend, and frontend layers for more flexible enterprise architecture.
Good to know
- Self-managed deployments require infrastructure and administration unless using ownCloud.online.
- Real-time document editing depends on configuring external office integrations such as Collabora, ONLYOFFICE, or Microsoft services.
- The main product positioning is organizational and enterprise-focused; small teams may need to compare the hosted option against simpler consumer cloud drives.
Under the radar: Before building a custom integration, check the ownCloud Marketplace, since extensions may already cover common add-ons and admin workflows.
