Crisis Mesh Messenger

A decentralized, infrastructure-free messaging application for crisis situations.

Overview

Crisis Mesh Messenger enables people to communicate when traditional infrastructure (internet, cell towers) fails due to:

Natural disasters
War and conflict
Censorship
Remote locations

Messages hop from device to device using Bluetooth and WiFi Direct, creating a resilient mesh network that requires no central infrastructure.

Key Features

✅ No internet or cell towers required
✅ Device-to-device messaging (Bluetooth/WiFi)
✅ End-to-end encryption
✅ Store-and-forward routing
✅ Works on Android and iOS
✅ Free and open source

Quick Start

# Install dependencies
flutter pub get

# Run on Android
flutter run

# Run on iOS
flutter run -d iPhone

Architecture

Technology Stack

Framework: Flutter 3.29+
State Management: Provider + GetIt (MVVM)
Local Storage: Hive (encrypted)
Communication:
- Android: Nearby Connections API, WiFi Direct, Bluetooth LE
- iOS: Multipeer Connectivity, Bluetooth LE
Encryption: End-to-end using libsodium
