It’s a community-fork of ownCloud with all components being open source. :)

It Is quite similar to ownCloud, but it includes the ownCloud Enterprise Features like Collabora Online, Calender, Contacts etc... also in the free community version. The focus of Nextcloud is to be secure (2 factor auth). PS: Theres a better AppStore in Nextcloud and apps are more supported and get more updates.

It is much easier to install and much more extensible, while still offering almost all features of the ownCloud.

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!
