Bonjeff

Bonjeff is a macOS utility that continuously monitors and displays Bonjour (mDNS) services advertised on the local network. It presents the information in a live, graphical interface, allowing users to see which devices and services are currently discoverable. The app serves as a modern replacement for the discontinued Bonjour Browser, offering the same core functionality with up‑to‑date macOS security compliance.

Because Bonjeff is code‑signed and notarized, it can be installed on Macs that enforce Gatekeeper without requiring any work‑arounds. The binary is distributed as a standard .app bundle that can be placed in the Applications folder, and removal is as simple as moving the app to the Trash. The source includes an Xcode project configured for developers who wish to build their own signed version, provided they supply a valid Apple Developer Team ID.

The software is authored by Jeff Johnson, released under the terms specified in its LICENSE.txt file, and is marked as stable for general use on macOS systems.
