    OwnCloud is groupware. Seafile is a file-sync storage solution. Just because they have overlapping functionality, does NOT make them interchangeable.

    It is similar to ownCloud in that it's self-hosted. Does not have apps such as Calendar, and is not compatible with the Federated Cloud sharing (ownCloud+Nextcloud+Pydio)

    Although tailored for families, it offers many of the same features as a typical groupware solution like OwnCloud -- calendaring, group messaging, sharing of files & content, etc.

    OwnCloud is groupware. SyncTrayzor is a "wrapper" for SyncThing, a file-sync storage solution. Just because they appear have overlapping functionality, does NOT make them interchangeable. This is not even a standalone solution!
