Fediverse is a common name for interconnected social networks, blogs, and other websites that cooperate instead of competing.

I host my own fediverse server with Mastodon, and I made several projects and wrote multiple articles about it, including:

A tinted screenshot of the Fediverse Export Analyzer interface, showing a visualization of Mastodon user account with profile image and description in the left column, and various details, including account creation date, embedded first post, and posting frequency, and a scatter plot of all posts.
A tinted screenshot showing domains where I have followers and follow accounts blocked by one of Mastodon's instances.
