Zap is a social networking server implementing the Zot6 protocol. This is the first reference implementation of that protocol. The network is sparse at the moment with only a small handful of pioneers. Integration with legacy Zot applications (such as Hubzilla and Red) is scheduled for later in the year.
Osada is a social networking server implementing both ActivityPub and Zot6. It can communicate with both networks.
These projects represent tradeoffs between different social networking and social media features. Osada provides greater social reach, with a corresponding loss of privacy controls and account resilience (nomadic identity). Zap provides the full capabilities of Zot, which includes privacy controls, private media, and account resilience; with a corresponding lack of federation with networks that do not offer these features -- hence a much smaller and more intimate social graph.
Both projects and a handful of addons/apps are available now from https://framagit.org/macgirvin
. These both use the LAMP stack and are licensed under the MIT license.
