WiFiSpy
WiFiSpy is a lightweight macOS utility that displays your current WiFi link speed in the menu bar, providing at-a-glance visibility into your wireless connection quality and bandwidth. The app is designed for users who want quick access to connection statistics without opening a full network settings window or system monitor.

1 suggestionWiFiSpy appears to be abandoned — the MacRumors discussion from 2018 noted the app had not been updated for a long time at that point, and no evidence of development activity has emerged since then. There is no native Apple Silicon build and there is unlikely to be one. The Intel build still runs today under Rosetta 2, but Apple is removing Rosetta in macOS 28 (September 2028), so this app will stop working entirely on that release. If you rely on WiFiSpy for quick WiFi speed monitoring, consider switching to iStat Menus or Bartender, both of which run natively on Apple Silicon and include WiFi and network monitoring widgets for the menu bar. Alternatively, the free system-native approach is to use Wireless Diagnostics (found in Applications → Utilities) or Control Centre, which display connection information without requiring a third-party app.
