    For those who prefer FOSS, Nextcloud is the way to go. ownCloud is partially proprietary so they have a different philosophy.

    Seafile is a more focussed, nimbler sync & share solution compared to Nextcloud (and the original ownCloud) that excels in performance and stability.

    I tried NextCloud and it was very hard to set up permissions in a enterprise environment. Seafile is simpler

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

    It's compatible with Federated Cloud sharing, meaning it can send and receive shares from Nextcloud and ownCloud servers as well
