delightful-activitypub-development/watchlist-for-activitypub-apps.md

This is the list of projects that may be implementing ActivityPub, which began in issue https://gitlab.com/fediverse/fediverse.gitlab.io/issues/8

*Note*: none of these apps ought to be added to the official fediverse.party site until they have been tested with at least one (ideally 2-3) of the AP apps already listed, and can be confirmed to federate successfully. Once it is on the official site, it can be removed from this list, keeping it a list of apps to be watched/ tested.

*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:

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:

*Events Apps*

* [Calendar-social](https://gitea.polonkai.eu/gergely/calendar-social/issues/122) - no specific mention of ActivityPub on the repo but rumour on the fediverse is that it will be an AP app. I will post a question on their issue tracker.

Proposed Projects

A place to list rumoured projects for further research, and vapourware, projects that have been planned but no usable code has been written yet.

* [CloutStream](https://pinafore.social/accounts/25168) - a federated replacement for LinkedIn

* [CommonsPub](https://gitlab.com/OpenCoop/CommonsPub) - a fork of Pleroma intended to provide a UX that supports economic transactions and coordination

* [Communecter](https://github.com/pixelhumain/communecter) - already supports ActivityStreams, plans to implement the rest of AP soon

* [Numa](https://github.com/numaverse/numaverse-gateway/issues/3) - built on Ethereum blockchain but intends to federate with AP. No commits since early 2017. Dead project?

* [Spritely](https://gitlab.com/spritely/spritely) - a new federated media-streaming server in Ratchet, planned by Chris Webber of MediaGoblin fame
