PeerChat is a production-grade, zero-infrastructure messaging platform. It connects devices using only their local hardware—Bluetooth, WiFi Direct, and Hotspots—to create self-healing mesh networks that survive without cell towers or internet.
- 🌐 Multi-Transport Mesh Networking: Intelligent routing that automatically selects the best path using Bluetooth, WiFi Direct, or Hotspot relays.
- 🌍 Web Share Proxy: Share files instantly to any device with a browser via an embedded local HTTP service.
- 🔒 Libsodium E2EE: Absolute message confidentiality using Ed25519 signatures for identity and X25519 for encryption.
- 📡 Multi-Hop Routing: Messages find their way through intermediate peers to reach out-of-range devices.
- 🎨 Premium UX: A beautiful, harmonized "Ink & Violet" design system with smooth animations and responsive layouts.
PeerChat follows a professional Continuous Delivery pipeline:
- Automated Releases: We use GitHub Actions to build and publish signed APKs automatically upon tag pushes.
- Dynamic Downloads: Our website always serves the latest version directly from GitHub via a custom proxy API.
- Real-time Changelog: The app's history is fetched dynamically from GitHub, ensuring you always see the latest improvements.
- Download the latest APK from peerchat.mathi.live.
- Grant Bluetooth, Location, and File permissions.
- Bring two devices close together—they will auto-discover and establish a secure handshake.
