Zap (discontinued)
Template:Infobox defunct/en Zap was the name of a roughly Facebook-like Fediverse project that featured channels and nomadic identity.
It was somewhat similar to Hubzilla, but slimmed down a lot. It didn't have nearly as many external connections anymore, and early in its experimental phase, it didn't have any. In comparison with Hubzilla, it had some UI improvements.
On New Year's Eve 2022, it was officially discontinued and superseded by its own most recent descendent, the code of which resides in the Streams repository, and which is very similar in features and handling.
Zap no longer has active instances.
