Mechanics

ActivityPub is an open, decentralized social networking protocol based on Pump.io's ActivityPump protocol.[1] It provides a client/server API for creating, updating, and deleting content, as well as a federated server-to-server API for delivering notifications and content.[2]

Project status

ActivityPub is a standard for the Internet in the Social Web Networking Group of the World Wide Web Consortium (W3C). The standard was co-authored by Evan Prodromou,[3] creator of StatusNet (now known as GNU social). At an earlier stage, the name of the protocol was "ActivityPump", but it was felt that ActivityPub better indicated the cross-publishing purpose of the protocol. It is the most widely supported standard (by some margin) in the Fediverse.[citation needed]

In January 2018, the World Wide Web Consortium (W3C) published the ActivityPub standard as a Recommendation.[2] Lead author Christine Lemmer-Webber notes that the team predominantly identified as queer, which led to features that help users and administrators protect against "undesired interaction." She also notes that the team authoring ActivityPub had no corporate participation.[4]

The W3C Social Community Group organizes a yearly free conference called ActivityPub Conf about the future of ActivityPub.[5][6]

Former Diaspora community manager Sean Tilley wrote an article that suggests ActivityPub protocols may eventually provide a way to federate Internet platforms.[7]

Notable implementations

Federated (server-to-server) protocol

  • Friendica, social networking software; implemented ActivityPub in version 2019.01.[8]
  • Kbin, a news aggregator and discussion forum similar to Reddit and Lemmy.[9]
  • Lemmy, software for running Reddit-style news aggregators and discussion forums. Any instance can use ActivityPub to interact with other forums and form a federated social network.[10]
  • Libervia (in beta as of 2022)[11]
  • Mastodon, social networking software; implemented ActivityPub in version 1.6 and released in September 2017. It is intended that ActivityPub offers more security for private messages than the previous OStatus protocol.[12][failed verification]
  • Micro.blog, a microblogging social network, added support for ActivityPub in 2018[13] and was enabled by default for new users in October 2022.[14]
  • Misskey, a federated self-hosted software for microblogging with special reaction and Markdown formatting, akin to Tumblr and Discord, mostly popular in Japan.
  • Nextcloud, a federated file-hosting service.[15][16]
  • PeerTube, a federated video-streaming service.[12]
  • Pixelfed, a federated image-sharing service resembling Instagram.[17]
  • Pleroma, a lightweight fediverse server implementing ActivityPub since its first release.[18]
  • WordPress via a plug-in to post blogs from users.[19]
  • WriteFreely, an open source and hosted blogging platform.[20]
  • BookWyrm, a federated social networking platform to track your reading, talk about books, and write reviews similar in functionality to Goodreads.[21]

Expected or announced implementations

  • In November 2022, Tumblr announced that they will be adding support.[22]
  • Threads, an Instagram application.[23]
