SparkDns is a lightweight, native desktop application for managing and optimizing DNS settings across Windows, Linux, and macOS. Built with Tauri 2 (Rust backend + TypeScript frontend), it provides real-time DNS switching, diagnostics, and system tools without the memory overhead of Electron.
Privacy First: All DNS operations run locally on your machine. No data is sent to external servers.
Switch between pre-configured DNS providers or create custom profiles with IPv4/IPv6 support.
Run comprehensive DNS diagnostics with latency testing, DNSSEC validation, leak detection, and reachability probes against configurable targets.
Flush DNS cache, renew DHCP, reset network adapters, and run traceroute — all from one panel.
Automatically switch DNS profiles based on network conditions or triggers.
Backup and restore your DNS configuration with JSON export/import.
System-aware theme with manual toggle support.

FAQ
Why does DNS switching require elevation? Modifying system DNS settings is a privileged operation on all operating systems. SparkDns will prompt for elevation when needed.
Does SparkDns work on ARM devices? SparkDns supports x86_64 on all platforms. ARM support depends on Tauri and Rust target availability.
Is my DNS traffic encrypted? SparkDns configures your system DNS servers. For encrypted DNS, enable DNS-over-HTTPS in settings (Windows and macOS only).
