How we chose these Dropbox alternatives

We looked for projects that cover Dropbox's core: storing, syncing, and sharing files across devices. We verified each project's license, recent activity, stars, and self-hosting options in its GitHub repository. Dropbox is a hosted service, so the list mixes full sync platforms, encrypted drives, document archives, and web file managers that sit on top of storage you already have. We flag projects that are source available or use non-commercial licenses. See our methodology for the full criteria.

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.

Why look for a Dropbox alternative?

Dropbox is a proprietary cloud storage service whose data lives on its servers and whose storage and features depend on paid plans. Open-source alternatives let you host your own files, choose where data is stored, encrypt it end to end, and avoid per-seat pricing, at the cost of running and maintaining the service yourself.
