Fediverse
The Fediverse is a collection of social networking services that can communicate with each other using a common protocol. Users of different websites can send and receive status updates, multimedia files and other data across the network. The term Fediverse is a portmanteau of federation and universe.
Fedify
Fedify is a TypeScript library for building federated server apps powered by ActivityPub and other standards, so-called fediverse.
ActivityPub
ActivityPub is a protocol and open standard for decentralized social networking. It provides a client-to-server (C2S) API for creating and modifying content, as well as a federated server-to-server (S2S) protocol for delivering notifications and content to other servers. ActivityPub is the defining standard of the Fediverse, a decentralised social network of various social interaction models, and content types, which consists of independently managed instances of software such as Mastodon, Pixelfed and PeerTube, among others.
ActivityPub
The ActivityPub protocol is a decentralized social networking protocol based upon the [ActivityStreams] 2.0 data format. It provides a client to server API for creating, updating and deleting content, as well as a federated server to server API for delivering notifications and content.

Agentic Fediverse | Muni Town | Weird.One
The "Agentic Fediverse" is the idea of a new kind of network federation, a complementary iteration on the concept of federation currently established with ActivityPub. It's an experiment and something that we in Muni Town are still trying to define more concretely.
Welcome | Takahē
Takahē is an ActivityPub server designed for efficient use on small- to medium-size installations, and which allows you to host multiple domains on the same infrastructure. It’s currently in an beta state, meaning most things work and it can talk to most of the Fediverse, but there’s still some polish and features left to add. The flagship instance can be found at takahe.social, and if you’re interested, you can also learn more in our documentation, browse the code on our GitHub repository, come and chat to us on Discord, or read some of Andrew’s blogs about building it.
Fediverse Observer checks all sites in the fediverse and gives you an easy way to find a home from a map or list or automatically.
