What is Hubzilla?/it: Difference between revisions

Hubzilla is a very powerful "jack-of-all-trades" in the {{Internal Link |target=What is the Fediverse? |link-name=Fediverse}}, often described as a decentralised social content management system, but with social networking, microblogging and cloud features.

Hubzilla's Web interface is extensively themeable, much like wholly different Web interfaces for {{Internal Link |target=What is Mastodon? |link-name=Mastodon}}, but as of now, there is only one supported theme, Redbasic. It can be extensively configured, though. It also has a dark mode that can be activated manually or automatically.

{{Internal Link |target=What is Mastodon? |link-name=Mastodon}} apps don't work with Hubzilla.

Also, channels aren't bound to one hub. They also make {{Internal Link |target=What is nomadic identity? |link-name=nomadic identity}} possible: You can clone any of your channels across two or more hubs, and these clones always stay in sync. It basically gives you real-time backup.

Hubzilla supports single sign-on via {{Internal Link |target=What is OpenWebAuth? |link-name=OpenWebAuth}}. If you're logged in, other instances with OpenWebAuth can recognise you and, for example, give you special permissions. OpenWebAuth even takes into account which one of your channels is currently active.

Each connection can be configured extensively. It can be assigned a contact role which is a customisable set of permissions. It can be added to one or several privacy groups which are similar to Friendica groups, {{Internal Link |target=What is diaspora*? |link-name=diaspora*}} aspects, Google+ circles or Mastodon groups. It can be assigned a profile if multiple profiles are activated. It can be blocked, ignored, hidden or archived, and so forth.

Streams are Hubzilla's timelines. The equivalent to Mastodon's personal timeline is the channel stream. However, it is more flexible: Only direct messages, posts/comments marked with a star or posts/comments from the channel itself can be shown. Also, all posts/comments from a certain privacy group, all threads from a certain forum (amongst others, Hubzilla recognises Friendica discussion groups and {{Internal Link |target=What is Lemmy? |link-name=Lemmy}} communities as such), all filed posts/comments from a certain category (similar to Mastodon's bookmarks, but with folders as categories) can be shown, and all posts/comments from a certain contact can be shown.

Hubzilla does not have anything like Mastodon's local timeline. There is also the public stream, pubstream in short, which is the equivalent to Mastodon's federated timeline. It can be activated by the hub admin, it is off by default, and most hubs keep it off in order to stay out of trouble because it is unmoderated.

Just like Friendica, (streams), Lemmy and {{Internal Link |target=What is Kbin? |link-name=/kbin}}, Hubzilla has a different thread structure than most of the rest of the Fediverse. Most Fediverse projects have threads like Twitter/X which consist of any number of technically identical posts. Friendica, Hubzilla and (streams) are more like Facebook, Tumblr, forums or comment sections on blogs or news sites: Their threads consist of exactly one post at the beginning, and everything that follows is not a post, but a comment.

The handling of images and other media is a lot different from Mastodon and other micro-blogging projects. They aren't uploaded and attached to posts. Instead, they're first uploaded to the managed file space which is part of each channel. Then they are embedded into posts or, with a trick, comments as links to the uploaded files. {{Internal Link |target=How to add alt-text to images on Hubzilla and (streams) |link-name=Alt-text is added by editing the BBcode}} and theoretically unlimited in length, too.

A feature like "retweeting" on Twitter/X, "reblogging" on Tumblr or "boosting" on Mastodon, i.e. forwarding posts as they are, is not available on Hubzilla.

Instead, posts and comments can be "shared" by referencing them in a new post or comment. It's basically the same as a "quote-tweet", but without copying the original post into the editor. For those who receive the post or comment, the reference is expanded to the whole shared post or comment, mentioning the author and giving a link to the original.
