*Note*: 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, are not added for now.
*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 watchlist](https://git.feneas.org/feneas/fediverse/wikis/watchlist-for-client-apps).
* 🎉 [Osada](https://wedistribute.org/2019/03/osada-is-being-sunsetted/) - creator has abandoned it. Not completely out of the question a community might form to continue maintenance as has happened with creators previous projects (Friendica, Hubzilla)
