✒ == newly added to this page (added, not altered. Only @light to remove please)
List of projects that have considered implementing one or more of the fediverse standards (OStatus, ActivityPub, Diaspora, Zot)
Note: once the developers of an app firmly commit to an implementation, please move it from this list to the watchlist for the relevant protocol. 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 watchlist.
*✒Chapter - a social events invite/ RSVP tool being developed by FreeCodeCamp.
✒🎉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?). Have an unmerged PR implementing AP support for following newsfeeds.
✒WT Social - social network for evidence-based news with crowdsourced flagging and fact-checking, founded by Jimmy Wales, who has said he's considering supporting AP. Currently proprietary but Wales says source code will be released in future.
✒Inventaire a libre collaborative resource mapper powered by open-knowledge.
Discontinued Projects That Considered Support for Fediverse Protocols
✒ postActiv - code forge and then homepage went offline in late 2019, followed by community.highlandarrow.com, one of the few postActiv instances (although highlandarrow.com is still live as of early 2020), none of them were archived on the WaybackMachine, so the links here are dead and kept for historical references. postActiv originally worked with OStatus. Considered implementing Zot, and implementing ActivityPub. As of May, 2019, lead dev had lost interest in AP.
