About:
DNSMonitor is a lightweight utility that monitors DNS queries in real-time on macOS. It provides visibility into which applications are making network requests and to which domains, helping users identify suspicious or unwanted network activity. The tool presents a clear interface showing the process, domain, and type of DNS query for enhanced network transparency.
Key Features:
  • Real-time DNS query monitoring and logging
  • Process-to-domain mapping for network activity
  • Filtering and search capabilities for DNS events
  • Lightweight system resource usage
  • Clean, native macOS interface
Use Cases:
  • Security auditing to detect potential malware or spyware network activity
  • Debugging application network issues and unexpected domain connections
  • Privacy monitoring to understand what data your apps are sending
Alternatives:
  • Little Snitch – More comprehensive firewall with DNS monitoring, but more complex and paid
  • lsof + tcpdump – Built-in command line tools, free but requires technical expertise and lacks GUI
  • Wireshark – Deep packet analysis, powerful but overkill for simple DNS monitoring needs
