Is nextcloud 27.0.2 the same as nextcloud hub?

I installed nextcloud on my own server. Currently, I have reached version 27.0.2 with updates. I see it as nextcloud hub on the Nextcloud page. Is the nextcloud I installed the same thing as nextcloud hub? how can i check?

Yes they are one and the same. The Hub versioning scheme is just there for marketing purposes. See here: Maintenance and Release Schedule · nextcloud/server Wiki · GitHub
