Databag is an open-source, self-hosted messaging service for the decentralized web, featuring direct communication, federation, end-to-end encryption, audio and video calls, and more. It relies on a STUN/TURN relay server for NAT traversal, and testing has been done with coturn and pion. Users wanting to enable audio and video calls should set up their own relay server.
- Utilizes a Decentralized system for direct communication between the application and the server node, ensuring an efficient flow of information.
- Employs a Federated system where accounts on different nodes have the ability to communicate with each other, broadening the network of interaction.
- Makes use of Public-Private key based identity, which is not bound to any blockchain or hosting domain, ensuring the system's independence.
- Incorporates End-to-End encryption, meaning the hosting admin cannot view sealed topics, with the default being unsealed. This protects users' privacy and data security.
- Supports Audio and Video Calls. Note that the natural traversal requires a separate relay server, which helps to maintain the quality of calls.
- Implements Topic based threads where messages are organized by topic and not contacts, enhancing the clarity and organization of conversations.
- Lightweight in design, so much so that the server can run on a basic device like a raspberry pi zero v1.3. This makes the system accessible and easy to use.
- Achieves low latency through the use of websockets for push events to avoid polling, ensuring real-time updates and swift communication.
- Offers Unlimited accounts per node, which means you can host for your entire family, making it versatile and family-friendly.
- Provides Mobile alerts for new contacts, messages, and calls. It supports UnifiedPush, FCM, APN, ensuring users stay updated and alerted about new happenings.
