The original

Replacements

Listings that take over the same core job as GoodSync.

  • FreeFileSync

    Compares two folders, shows exactly what differs, and copies only what changed.

    FreeFileSync is free with published source and compares folders to copy only changes, with saved batch jobs, but it has no mobile apps and some conveniences require the Donation Edition.

  • Syncthing

    Keeps folders identical across your own machines, directly between them, with no cloud account in the middle.

    Syncthing is MPL-2.0 open source and syncs folders continuously between your own machines with versioning, but both devices must be online and Android relies on a community fork.

  • Resilio Sync

    Peer-to-peer file sync with no cloud server in the middle.

    Resilio Sync is free and syncs peer to peer across desktop and mobile with no cloud server, but it is also closed source and needs both devices online.

  • Rclone

    A command line tool that syncs, copies and mounts files across more than seventy cloud storage services.

    Rclone is MIT-licensed and covers more than seventy cloud storage services with checksums and client-side encryption, but it is command line only.

  • Unison

    Synchronize two file collections while preserving changes from both sides.

    Unison is free GPL-3.0 software for two-way sync that preserves changes from both sides, without the mobile apps or wide range of back ends of GoodSync.

  • rsync

    The classic delta-transfer tool for copying and mirroring files.

    rsync is free GPL-3.0 command-line software that sends only the changed parts of files, but it has no versioning or snapshots on its own.

  • Syncovery

    A file sync, backup and migration tool for local drives, network shares and cloud storage.

    Syncovery handles local, network and cloud storage on Windows, Mac, Linux and NAS devices, but has no mobile apps and remains paid and closed source.

  • SyncBack

    Windows backup and folder synchronization software with cloud storage, versioning and scripting support.

    PaidProprietaryWindows

    SyncBack offers backup, two-way sync, cloud destinations and scripting, but its main program runs only on Windows and full features need a paid edition.

Also worth comparing

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

  • Beyond Compare

    A tool for comparing, merging and synchronizing files and folders on Windows, macOS and Linux.

    A Mac app for synchronizing and backing up folders to drives, other Macs, NAS and cloud services.

    PaidProprietarymacOS

  • FolderSync

    A folder sync app for Android and desktop that works with over 20 cloud providers.

    GoodSync adds block-level transfer and versioning across Android, iOS and desktops, but requires a paid per-user licence and is closed source.
