Important: not every project is fully open source
Spacedrive uses the Functional Source License (FSL-1.1-ALv2), which is source available and converts to Apache-2.0 after two years. Hoodik uses CC BY-NC 4.0, a non-commercial license that is not OSI-approved open source, so it is unsuitable for business use. Seafile, OpenCloud, and ownCloud mix licenses across components, and Peergos is AGPL-3.0 at its core.
Sync platforms vs file managers
Nextcloud, Seafile, OpenCloud, ownCloud, Sync-in, and Twake Drive are full sync-and-share platforms with desktop and mobile clients. Filestash and Firefiles are web interfaces over storage you already have, such as S3, SFTP, or WebDAV, and do not provide storage themselves. Papra archives documents, and Spacedrive unifies files across devices.
Encryption and privacy
Ente, Peergos, and Hoodik encrypt files on the client before upload. Peergos adds a peer-to-peer architecture, and Ente focuses on photos and videos rather than general files. Nextcloud, Seafile, and Twake Drive offer encryption options with different trade-offs for features such as search and web editing.
Collaboration and office editing
Nextcloud adds calendars, chat, video calls, and real-time document editing. OpenCloud, ownCloud, Sync-in, and Twake Drive integrate office suites such as OnlyOffice or Collabora, while Seafile offers real-time co-editing and file properties. Choose a full suite if you want to replace Dropbox Paper or Microsoft 365 integrations as well.
Maintenance status
Firefiles has had no commits since November 2025, so check it against your needs. Most other projects, including Nextcloud, Puter, Ente, Filestash, Sync-in, OpenCloud, and ownCloud, were updated within days of this update.
