Debookee is the simplest & most powerful network traffic analyzer for macOS.
Network Traffic Interception
Debookee is able to intercept and monitor the traffic of any device in the same subnet, thanks to a Man-in-the-middle attack (MITM)
It allows you to capture data from mobile devices on your Mac (iPhone, iPad, Android, BlackBerry...) or Printer, TV, Fridge (Internet of Things!) without the need of a proxy.
This interception is done in 1 click and is totally transparent, without network interruption.... More Info »
Network Analysis Module (NA)
The Network Analysis module monitors and analyze in real-time the network data of your own Mac, or the ones you're intercepting.
It currently supports HTTP, DNS, TCP, DHCP, SIP, RTP (VoIP) protocols.
It does NOT decrypt HTTPS yet. All features are available in the free trial.
WiFi Monitoring Module (WM)
The WiFi Monitoring module puts your Wi-Fi network interface in monitoring mode and listens to all 802.11 radio frames around.
You'll see not only Access Points, but also all Wi-Fi clients in your radio range, if they're associated or not, and details on their connection.
Debookee WM module shows bidirectional infos for each client connection: from AP to client and client to AP (Data Rate, %Retries, %Errors ...)
