It runs on a Raspberry Pi with a 2.13-inch e-Paper HAT, as a headless server on Debian-based systems (AMD64/ARM/ARM64) with Ethernet-first connectivity, or on the WiFi Pineapple Pager with full-color LCD display. On servers with 8GB+ RAM, Ragnar unlocks advanced capabilities including real-time traffic analysis and enhanced vulnerability scanning.

Quick Install
wget https://raw.githubusercontent.com/PierreGode/Ragnar/main/install_ragnar.sh
sudo chmod +x install_ragnar.sh && sudo ./install_ragnar.sh
# On Raspberry Pi: choose between e-Paper HAT, server/headless, or Pineapple Pager deployment.
# On other hardware: choose between server install or Pineapple Pager deployment.
# It may take a while as many packages and modules will be installed. Reboot when it finishes.

🌐 Web Interface
Access Ragnar's dashboard at http://<ragnar-ip>:8000
- Real-time network discovery and vulnerability scanning
- Multi-source threat intelligence dashboard
- File management with image gallery
- System monitoring and configuration
- Hardware profile auto-detection (Pi Zero 2W, Pi 4, Pi 5)
WiFi Configuration Portal — When Ragnar can't connect to a known network, it creates a WiFi hotspot:
- Connect to WiFi network
Ragnar(password:ragnarconnect) - Navigate to
http://192.168.4.1:8000 - Configure your WiFi credentials via the mobile-friendly interface
- Ragnar will automatically retry known WiFi after some time if the AP is unused
- Once configured, Ragnar exits AP mode and connects to your network
The portal supports network scanning with signal strength, manual entry for hidden SSIDs, known network management, and one-tap reconnection.

🐝 Ragnar + Pwnagotchi Side by Side
A bundled helper script plus dashboard controls make swapping between Ragnar and Pwnagotchi painless:
-
Run the installer:
cd /home/ragnar/Ragnar sudo ./scripts/install_pwnagotchi.shThe script clones pwnagotchiworking into
/opt/pwnagotchi, installs dependencies, writes/etc/pwnagotchi/config.toml, and drops a disabledpwnagotchi.service. Re-running is fast — it skips already-installed packages. -
Open the web UI → Config tab → Pwnagotchi Bridge → click Switch to Pwnagotchi.
Requirements:
- USB WiFi adapter (wlan1) with monitor mode support
- Waveshare 2.13" e-Paper HAT V4 for the pwnagotchi face display
Pwnagotchi web UI: http://<same-ip>:8080 (credentials: ragnar / ragnar)
What the installer configures:
- Monitor mode scripts (
/usr/bin/monstart,/usr/bin/monstop) - e-Paper display type (
waveshare213_v4) and rotation - Web UI on port 8080, Pwngrid disabled
- RSA keys, log directories, bettercap integration
