A cross-platform DNS manager with a dark-themed GUI — built with Python and Flet.
Quickly benchmark, switch, and manage DNS providers without touching system settings manually.
- Benchmark — measures latency and DNS response time for every provider in parallel
- One-click activate — sets the chosen DNS on your active network interface
- Built-in Iranian providers — Shekan, Electro, Begzar, Radar, Shellter, Beshkan, Shatell
- Custom DNS — add any DNS by IP, stored permanently in
~/.dns_manager_custom.json - Flush cache — clears the local DNS cache without changing DNS settings
- Clear DNS — reverts to automatic (DHCP) DNS with a confirmation prompt
- Cross-platform — macOS, Windows, Linux
- Python 3.10+
- pip packages listed in
