SnapDNS is a desktop tool that lets you switch your DNS providers (Google, Cloudflare, Quad9) quickly.
It solves the issue of Windows 10 not natively supporting DNS-over-HTTPS (DoH) for custom providers by running a lightweight local proxy in the background. It creates a system service to handle the network changes, so the UI doesn't need to run as Administrator.
- DNS-over-HTTPS (DoH): Uses a local proxy to enable encrypted DNS on Windows 10/11.
- Auto-Detect: Finds your active network adapter automatically (Wi-Fi or Ethernet).
- Profiles: Comes with Cloudflare, Google, and Quad9 preset. You can add your own.
- System Tray: Closes to the tray so it stays out of your way.
- Utilities:
- Flush DNS: Runs
ipconfig /flushdnswith one click. - Latency Check: Pings the server before you connect.
- Leak Test: Shortcut to open dnsleaktest.com.
- Flush DNS: Runs

- Download
SnapDns_Setup.exe. - Run the installer. It will register the background service automatically.
Currently source-only. Binary releases pending.
SnapDNS uses a split architecture to handle permissions securely:
- SnapDns.App (UI): The interface you see. It runs with standard user permissions.
- SnapDns.Service (Backend): A background service running as
LocalSystem.- The UI sends commands to the Service via Named Pipes.
- The Service executes the actual network changes (WMI/Netsh).
- If DoH is selected, the Service spins up a local UDP proxy on
127.0.0.1:53and tunnels requests over HTTPS.
