fediparty-wiki/watchlist-for-activitypub-apps.md

[Tools with open protocol issue (not yet implemented), not fully open sourced code, no documentation at all, or alpha state with development inactive for several months - not added for now]

List of projects that are or may be implementing ActivityPub, which began in issue https://gitlab.com/fediverse/fediverse.gitlab.io/issues/8

The SocialWG has a list of projects they hope will implement ActivityPub and links to Issues where it's discussed. Also, there is an implementation report on ActivityPub.rocks. @Mayel from Social.coop is maintaining a web spreadsheet of AP apps and their characteristics. More projects using AP are profiled on We Distribute by Sean Tilley. From these and other sources (see links), it looks like all these apps are either considering, working on, or already rolling out AP support:

Note: most of these projects include both a back-end and a web client, but this list can also include projects that are only a back-end. Projects that are only a web app, for use with an existing back-end, will go on the client watchlist here.

Social networks, Microblog Apps

• ✔ Aardwolf

• ✔ Friendica - AP support still in beta, due to be included in the December release of stable.

• ✔ Mastodon

• ✔ microblog.pub - single-user microblog server

• ✔ microstatus - Lightweight Mastodon- and GNU Social-compatible ActivityPub and OStatus server implementation

• ✔ Misskey

• ✔ Osada - an AP server that can also act as a bridge for smoother inter-operation between AP networks and Zot networks (Hubzilla)

• ✔ Pleroma

• ✔ postActiv

• pump.io

• Pylodon - Flask-based (Python) ActivityPub server , article)

• ✔ Rustodon

• ✔ SocialHome - currently working on adding AP support to their Python federation library

• ✔ Kibou - highly customizable multi-protocol social networking server

• ✔ Smilodon

Blog and Publishing Apps

• ✔ Dokie.li

• ✔ FediBlog - fully customisable blog engine

• ✔ Huzbilla - federated CMS with a range of groupware tools available as plug-ins. Support AP with the pubcrawl plug-in.

• Known

• ✔ Plume

• ✔ Read.as - a reading app

• ✔ WordPress - an AP plug-in by @pfefferle@mastodon.social, that allows users on AP apps to follow WP blogs, was recently updated. See also Pterotype, which @pfefferle says is currently more feature complete. WordPress is now listed as a project on the-federation.info.

• ✔ Write Freely

Link-sharing Apps

• Anancus

• ✔ Prismo

Media-hosting Apps

• ✔ Anfora (formerly Zinat) - image sharing

• MediaGoblin - streaming of any and all media files

• PeerPx - social network for photographers ("alternative to 500px / Flickr")

• ✔ PeerTube - video-hosting site using WebTorrent

• ✔ PixelFed - image sharing

• Quit.im - this is a photo-sharing web client for a GNU social server, rather than a completely separate app, so it will become an AP implementation when the AP plug-in for GS is done.

• snap.as - photo sharing

• ✔ reel2bits - Soundcloud-like

Events and Meetups

• Calendar-social - definitely planning to implement AP.

• Fedevent - a prototype for a "front-end for a bot account on Mastodon to send out notifications".

Friendica (see above) has an events engine but there are conflicting reports about whether or not federation of events over AP is working yet. NextCloud federated events are in the work but this may or may not be AP-compatible.

• tags.pub - AP implementation testing tool?

Relays reference

• ✔ Pub relay

• ✔ Activity relay

• ✔ Seattle relay

Proposed Projects and implementations in development

A place to list rumoured projects for further research, apps whose developers have expressed interest in implementing AP, and vapourware projects that have been planned but no usable code has been written yet. Once it's clear that the project really exists, is definitely working on implementing AP, and code is actually being committed, it can be moved to the appropriate category above.

• Communecter - already supports ActivityStreams, plans to implement the rest of AP. Codebase is currently being refactored into a set of smaller components.

• Dreamwidth - a blogging engine forked from LiveJournal.

• Ghost

• ✒ Human Connection

• Indienet - homepage - projects goals seem similar to the federated homepages of the IndieWeb, but federated using AP.

• ✒ Marmota - service like Spotify or any music streaming service, initial commit;

• Minds - a centralized attempt at a FB replacement, incorporating short or long form posts, and live chat, as well as an internal token system (a bit like Reddit gold?)

• Spritely - a new federated media-streaming server in Ratchet, planned by Chris Webber of MediaGoblin fame

Dead Projects

Listed on this watchlist just in case anyone doesn't realize they're dead, and thinks we just didn't know about them. Also in case a project is orphaned, then reactivated by a new developer.

• Acorde - federated social music platform. Almost a year has passed since the initial commit.

• ✖ CloutStream - proposed as a federated replacement for LinkedIn. Original Mastodon.social account appears to have been removed (copy on Pinafore), all the links projects tools appear to be down.

• ✖ Fontina - proposed as a photo-sharing social media network. GH repo has gone read-only, and now says "dead project".

• ✖ Numa - built on Ethereum blockchain but intends to federate with AP. No commits since April 2018. No reply on issue about AP compatibility testing from May 8.

• ✖ Osada - Osada is a full featured social network application running under the ActivityPub protocol. It also communicates with and inter-operates with servers on the Zot6 network. Abandoned by the developers in March 2019.
