Replacements

Listings that take over the same core job as Sync.com.

    PaidProprietaryWindowsmacOSLinuxAndroidiOSWeb

    Tresorit also applies zero-knowledge encryption, adds a Linux client, enterprise access controls and European data residency, but it is paid with no meaningful free tier.

  • Proton Drive

    End-to-end encrypted cloud storage from Proton for backing up, syncing and sharing files and photos.

    FreemiumProprietaryAndroidiOSWeb

    Proton Drive provides end-to-end encrypted storage with password-protected share links and mobile photo backup, but it requires a Proton account and lists no Windows or macOS platforms.

  • MEGA

    End-to-end encrypted cloud storage with a large free tier.

    FreemiumProprietaryWindowsmacOSLinuxAndroidiOSWeb

    MEGA offers end-to-end encryption by default with a larger free tier and a Linux client, but transfer quotas apply on free and lower paid tiers.

  • pCloud

    Swiss cloud storage with lifetime plans and optional client-side encryption.

    FreemiumProprietaryWindowsmacOSLinuxAndroidiOSWeb

    pCloud is Swiss storage with lifetime plans and a Linux client, but client-side encryption is a paid add-on rather than the default as on Sync.com.

  • Filen

    German end-to-end encrypted cloud storage with open-source clients.

    FreemiumOpen sourceWindowsmacOSLinuxAndroidiOSWeb

    Filen stores data in Germany with zero-knowledge encryption and open-source clients including Linux, but it is a smaller, newer provider with some rough edges.

  • Internxt

    Open-source, end-to-end encrypted cloud storage and photo backup.

    FreemiumOpen sourceWindowsmacOSLinuxAndroidiOSWeb

    Internxt offers client-side encryption with open-source clients, Linux support and lifetime plans, though its sync client reliability has been uneven and the free tier is small.

  • iCloud Drive

    Apple's cloud storage, integrated across macOS, iOS and Windows.

    FreemiumProprietaryWindowsmacOSiOSWeb

    iCloud Drive integrates tightly with macOS and iOS and offers end-to-end encryption via Advanced Data Protection, but the experience outside Apple platforms is poor.

  • Dropbox

    The original file sync service, with clients on every platform.

    FreemiumProprietaryWindowsmacOSLinuxAndroidiOSWeb

    Dropbox brings a mature sync engine with Linux clients and smart sync, but files are not zero-knowledge encrypted and the free tier is only a few gigabytes.

Also worth comparing

These listings name Sync.com as their own alternative, so the relationship runs both ways.

  • Peergos

    Self-hostable encrypted storage that hides sharing metadata as well as content.

    FreemiumOpen sourceWebSelf-hosted

    Sync.com is hosted zero-knowledge storage with clients for Windows, macOS, Android and iOS, but it is closed source with no Linux client.
