Databag

The server can run on a Raspberry Pi Zero v1.3, as stated in the README, making it exceptionally efficient for low-power hosting environments.

Accounts on different nodes can communicate directly, enabling a federated network without central control, which supports cross-instance interaction as per the design overview.

End-to-end encryption with sealed topics prevents server admins from viewing message content, ensuring user privacy as highlighted in the key features.

Topic-based threads allow unlimited participants and organize messages by subject rather than contacts, offering a unique approach to group conversations.
