Free, unlimited VPN solution with a server in France. Fully open source and customizable.
Download the Shadowguard Setup 1.0.0.exe.
Run the installer and complete the installation.
After installation, navigate to:
C:\Program Files\Shadowguard
Place your wg-client.conf file inside this folder alongside the other Shadowguard files.
Important: The VPN cannot connect without this configuration file.
Right-click on Shadowguard.exe and select:
Run as Administrator
The app requires admin permissions to control VPN connections.
In some cases, WireGuard is not automatically installed.
If this happens:
Follow these steps to set up your personal VPN server on any VPS provider.
Connect to your VPS via SSH:
ssh root@your_vps_ip
Enter your password when prompted.
apt update apt install wireguard -y
wg genkey | tee server_privatekey | wg pubkey > server_publickey
View and save your server private key:
cat server_privatekey
Tip: Keep your private keys secure! Never share them.
nano /etc/wireguard/wg0.conf
Paste the following configuration (replace with your private key):
[Interface] PrivateKey = YOUR_SERVER_PRIVATE_KEY Address = 10.0.0.1/24 ListenPort = 51820 PostUp = iptables -A FORWARD -i wg0 -j ACCEPT; iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE PostDown = iptables -D FORWARD -i wg0 -j ACCEPT; iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE
Save and exit (Ctrl+X, Y, Enter).
echo "net.ipv4.ip_forward=1" >> /etc/sysctl.conf sysctl -p
ufw allow 51820/udp ufw allow OpenSSH ufw enable
wg-quick up wg0 systemctl enable wg-quick@wg0
Check the status:
wg
Generate client keys:
wg genkey | tee client_privatekey | wg pubkey > client_publickey
Add the client to the server config:
nano /etc/wireguard/wg0.conf
Add at the bottom (replace with client public key):
[Peer] PublicKey = CLIENT_PUBLIC_KEY AllowedIPs = 10.0.0.2/32
Restart WireGuard:
wg-quick down wg0 wg-quick up wg0
Create the client configuration file:
[Interface] PrivateKey = CLIENT_PRIVATE_KEY Address = 10.0.0.2/24 DNS = 1.1.1.1 [Peer] PublicKey = SERVER_PUBLIC_KEY Endpoint = YOUR_VPS_IP:51820 AllowedIPs = 0.0.0.0/0 PersistentKeepalive = 25
Save this as wg-client.conf and use it with ShadowGuard VPN.
The ShadowGuard VPN client is built using Electron, allowing it to run as a standalone desktop application on Windows, macOS, and Linux.
Note: While Electron provides a convenient way to build cross-platform desktop apps, there are other approaches to creating VPN clients, such as native applications or browser extensions. The Electron approach was chosen for its cross-platform capabilities and ease of development.
