🛡 Hosts & Firewall Manager

Take full control of your Windows network — no technical knowledge required.

Hosts & Firewall Manager is a clean, modern desktop tool that lets you manage your Windows hosts file and firewall rules with just a few clicks. No command line, no registry digging, no guesswork.

✨ Features

🗂 Hosts File Editor

• Add and remove custom DNS entries instantly
• Automatic backup before every change — restore with one click if something goes wrong
• Flush DNS button to apply changes immediately without restarting
• Dangerous entry detection — entries that redirect known system domains (Microsoft, Google, Windows Update) are highlighted with a red border

🔥 Firewall Manager

• Block any program from accessing the internet in seconds
• Choose the direction: Inbound, Outbound, or Both
• Browse installed programs directly from the Windows registry — no need to hunt for .exe files manually
• Verify rules are active — each blocked program shows ✅ or ❌ to confirm the rule actually exists in Windows Firewall
• Unblock programs with one click

🔒 How it works

The tool uses standard Windows APIs:

• hosts file editing (requires admin privileges)
• netsh advfirewall for firewall rules
• Windows Registry for installed program detection

Always runs as Administrator — required for hosts file and firewall access. The app will prompt you on launch.

💡 Use cases

• Block a program from phoning home or sending telemetry
• Redirect domains locally for development or privacy
• Quickly disable internet access for a game or app
• Keep a clean backup of your hosts file before making changes

Free to use. No ads, no tracking, no nonsense.
