Building from Source 🛠️

Click to expand build instructions

Prerequisites

# Install Rust 🦀
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

# Install Node.js (v18+) 📦
# Download from nodejs.org or use nvm

Steps

git clone https://github.com/arelove/dns-switcher.git
cd dns-switcher

npm install

# Run in development mode
npm run tauri dev

# Build for production
npm run tauri build

The installer will be located in:
src-tauri/target/release/bundle/

Tech Stack 🔧

• Frontend: SvelteKit + TypeScript
• Backend: Rust (via Tauri)
• Styling: Pure CSS (no frameworks)
• Build tool: Vite

Tauri provides much smaller binaries, superior performance, and a truly native experience — far better than Electron in most cases.

How It Works Under the Hood 🔍

The application uses Windows netsh commands to modify DNS settings on each network adapter individually.
This is why a UAC (admin rights) prompt appears on first launch.
DNS changes are applied per-adapter (not globally), which properly respects VPN connections, different Wi-Fi profiles, Ethernet, etc.

Known Limitations ⚠️

• DNS changing requires administrator privileges (Windows limitation)
• Some VPN software may override applied DNS settings

Roadmap 🗺️

Planned / considered features:

• macOS and Linux support
• Automatic network profile detection (home / office / public)
• DNS server latency & speed testing
• Import / export of presets
