Databag is a fast, lightweight, self-hosted federated messenger with end-to-end encryption, audio/video calls via WebRTC, and topic-based threads. It consists of a Go server node that can run on minimal hardware like a Raspberry Pi Zero, plus mobile and web clients.

Use cases

• self-host a private chat messenger for family or team
• run a messaging server on a raspberry pi zero
• federated chat between accounts on different servers
• end-to-end encrypted messaging the host admin cannot read
• make audio and video calls with a self-hosted messenger
• host unlimited chat accounts on one node
• replace proprietary messengers with a decentralized alternative

When to choose

• you want full control over your messaging infrastructure on cheap hardware
• you need federated communication across independently hosted nodes
• you want E2E encryption plus voice/video calls in one self-hosted app
• you need mobile apps from F-Droid, Play Store, or App Store

When to avoid

• you need a managed hosted service with no server maintenance
• you require integration with existing enterprise chat ecosystems like Slack or Teams
• you need large-scale centralized deployment with horizontal scaling out of the box
• you want a messenger with a large existing user network
