✔ == **added to website** [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 may be implementing ActivityPub, which began in issue https://gitlab.com/fediverse/fediverse.gitlab.io/issues/8 *Note*: most of these projects include both a back-end and a web client, but this list also includes 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 list [here](https://gitlab.com/fediverse/fediverse.gitlab.io/wikis/watchlist-for-client-apps). The [SocialWG has a list](https://www.w3.org/wiki/Socialwg/ActivityPub_network) of projects they hope will implement ActivityPub and links to Issues where it's discussed. Also, there is an [implementation report on ActivityPub.rocks](https://activitypub.rocks/implementation-report/). @Mayel from Social.coop is maintaining a [web spreadsheet of AP apps](https://ethercalc.org/fediverse-stacks) and their characteristics. More projects using AP are [profiled on We Distribute](https://medium.com/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: #### Social network, Microblog Apps * ✔ [Aardwolf](https://github.com/Aardwolf-Social/aardwolf) * [Indienet](https://source.ind.ie/project/heartbeat-cocoa/issues/194#note_10162) * ✔ [Kroeg](https://git.puckipedia.com/kroeg) * [pump.io](https://github.com/pump-io/pump.io/issues/1241) * ✔ [microblog.pub](https://github.com/tsileo/microblog.pub) - single-user microblog server * ✔ [Osada](https://macgirvin.com/wiki/mike/Osada/Home) - an AP server that can also act as a bridge for smoother inter-operation between AP networks and Zot networks (Hubzilla) * ✔ [Rustodon](https://github.com/rustodon/rustodon) * [Pylodon](https://github.com/rowanlupton/pylodon) - Flask-based (Python) ActivityPub server ([Smilodon client](https://github.com/rowanlupton/smilodon), [article](https://blog.rowan.website/2017/12/23/pylodon)) * [PeerPx](https://github.com/peerpx) - social network for photographers ("alternative to 500px / Flickr") * [Kitsune](https://github.com/valerauko/kitsune) - microblogging * [microstatus](https://github.com/Arkanosis/microstatus) - Lightweight Mastodon- and GNU Social-compatible ActivityPub and OStatus server implementation * [Acorde](https://github.com/polymerwitch/Acorde) - federated social music platform (initial commit) #### Blog and Publishing Apps * ✔ [Dokie.li](https://dokie.li) * [Ghost](https://forum.ghost.org/t/federate-over-activitypub/1989/15) * [Known](https://github.com/idno/Known/issues/1701) * ✔ [Plume](https://github.com/Plume-org/Plume) * ✔ [Write Freely](https://writefreely.org) * ✔ [Read.as](https://github.com/writeas/Read.as) - a reading app * ✔ [FediBlog](https://framagit.org/DavidLibeau/FediBlog) - fully customisable blog engine * [WordPress](https://gitlab.com/fediverse/fediverse.gitlab.io/wikis/Wordpress-integration-with-Fediverse) - an [AP plug-in](https://wordpress.org/plugins/activitypub/) by @pfefferle@mastodon.social, that allows users on AP apps to follow WP blogs, was recently updated.
