[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]
*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).
* [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)
