Microblogging is a form of blogging using short posts without titles known as microposts. Microblogs "allow users to exchange small elements of content such as short sentences, individual images, or video links", which may be the major reason for their popularity. Some popular social networks such as X (Twitter), Threads, Tumblr, Mastodon and Instagram can be viewed as collections of microblogs.
identi.ca is a free and open-source social networking and blogging service based on the pump.io software, using the Activity Streams protocol. Identi.ca stopped accepting new registrations in 2013, but continues to operate alongside several other pump.io-based hosts provided by E14N which continue to accept new registrations.
GNU social is a free and open-source microblogging social networking service that implements the OStatus and ActivityPub standards for interoperability between installations. While offering similar functionality to social networks such as Twitter, GNU social seeks to provide the ability for open and federated communication between different microblogging communities, known as 'instances'. Both enterprises and individuals can install and control their own instances and user data.
OpenMicroBlogging is a deprecated protocol that allows different microblogging services to inter-operate. It lets the user of one service subscribe to notices by a user of another service. This enables a federation of new communities, as potentially an organization of any size can host a service. OpenMicroBlogging utilizes the OAuth and Yadis protocols and does not depend on any central authority.
GitHub is a developer platform that allows developers to create, store, manage and share their code. It uses Git software, providing the distributed version control of access control, bug tracking, software feature requests, task management, continuous integration, and wikis for every project. Headquartered in California, it has been a subsidiary of Microsoft since 2018.
Diaspora is a nonprofit, user-owned, distributed social network. It consists of a group of independently owned nodes which interoperate to form the network. The social network is not owned by any one person or entity, keeping it from being subject to corporate take-overs or advertising. According to its developer, "our distributed design means no big corporation will ever control Diaspora."
OStatus is an open standard for decentralized social networking, allowing users on one service to send and receive status updates with users from another. The standard describes how a suite of various standards, including Atom, Activity Streams, WebSub, Salmon, and WebFinger, can be used together, which enables different microblogging server implementations to communicate status updates between their users back-and-forth, in near real-time.
Friendica is a free and open-source software distributed social network. It forms one part of the Fediverse, an interconnected and decentralized network of independently operated servers.
Distributed social network projects generally develop software, protocols, or both.
Evan S. Prodromou is a software developer and open source advocate. He is a co-editor of ActivityPub, the W3C standard for decentralized social networking used by platforms such as Mastodon.
Twister is a decentralized, experimental peer-to-peer microblogging program which uses end-to-end encryption to safeguard communications. Based on BitTorrent- and Bitcoin-like protocols, it has been likened to a distributed version of Twitter.
pump.io is a software package containing a social networking service and communication protocol that can be used as a federated social network. Started by Evan Prodromou, it is a follow-up to his previous microblogging software StatusNet and its OStatus protocol. It is designed to be more lightweight and usable for general activity streams instead of the predecessor's focus on microblogging timelines, with its goal being to achieve "most of what people want from a social network".
Movim is a distributed social network built on top of XMPP, a popular open standards communication protocol. Movim is a free and open source software licensed under the AGPL-3.0-or-later license. It can be accessed using existing XMPP clients and Jabber accounts.
Mastodon is free and open-source software for running self-hosted social networking services. It has microblogging features similar to Twitter, which are offered by a large number of independently run nodes, known as instances or servers, each with its own code of conduct, terms of service, privacy policy, privacy options, and content moderation policies.
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".
Micro.blog is a microblogging and social networking service created by Manton Reece. It is the first large multi-user social media service to support the Webmention and Micropub standards published by the World Wide Web Consortium, and is part of the Fediverse, supporting ActivityPub.
ActivityPub is a protocol and open standard for decentralized social networking. It provides a client-to-server 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 has become the main standard used in the fediverse, a popular network used for social networking that consists of software such as Mastodon, Pixelfed and PeerTube.
Pixelfed is a free and open-source image sharing social network service. The platform uses a decentralized architecture which is roughly comparable to e-mail providers, meaning user data is not stored on one central server. It uses the ActivityPub protocol, allowing users to interact with other social networks within the protocol, such as Mastodon, PeerTube, and Friendica. Pixelfed and other platforms utilizing this protocol are considered to be part of the Fediverse.
Misskey is a free and open-source social networking service. Created in 2014 by Japanese software engineer Eiji "syuilo" Shinoda, Misskey was originally developed as bulletin board software. A microblogging feature similar to Twitter was added to the platform, which eventually became the main format of the service. The name Misskey comes from the lyrics of Brain Diver, a song by the Japanese band May'n.
