Hosts Editor

Hosts Editor is a native macOS application designed to easily view, edit,
back up, and restore your system's /private/etc/hosts file.

Built specifically for macOS using Swift and SwiftUI, Hosts Editor provides
a clean, intuitive user interface while handling system privilege escalation
and DNS cache management automatically.

KEY FEATURES

1. VIEW & SEARCH HOSTS ENTRIES
   - View all structured mappings in your /private/etc/hosts file.
