I got tired of digging through cluttered OS network settings every time I wanted to change my DNS provider (Cloudflare, Google, Quad9, etc.). It always felt like too many clicks for such a basic task.

To fix this, I built cdns in Go. It’s a minimal, single-purpose CLI tool that strictly follows the KISS principle. You run one command, pick your provider, and your system's DNS is updated instantly right from the terminal.

I'd love to hear your thoughts, any feedback on the Go implementation, or if you run into any OS-specific edge cases!
