Databag

Notable features of Databag include:

- Decentralized (direct communication between app and selfhosted server)

- Federated (accounts on different nodes can communicate)

- Public-Private key based identity (not bound to any blockchain or hosting domain)

- End-to-End encryption (the hosting admin cannot view sealed topics, default unsealed)

- Audio and Video Calls (nat traversal requires separate relay server)

- Topic based threads (messages organized by topic not contacts)

- Lightweight (server can run on a raspberry pi zero v1.3)

- Low latency (use of websockets for push events to avoid polling)

- Unlimited accounts per node (host for your whole family)

- Mobile alerts for new contacts, messages, and calls (supports UnifiedPush)
