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

OwnCloud is groupware. IPFS 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.
