Packet Peeper

Packet Peeper is a macOS‑only utility that captures and displays network traffic, allowing users to inspect individual packets and the protocols they use. It provides a graphical interface for viewing packet details, filtering by protocol, and navigating through captured data. The tool is built with Xcode and distributed as a disk image, with source code that can be compiled using standard Xcode commands and submodule initialization.

The software targets network administrators, developers, and anyone needing to analyze network communication on a Mac. It supports common protocols and presents the information in a readable format, facilitating troubleshooting and protocol study. The project follows a stable release cycle, with tags dated in a YYYY‑MM‑DD format automatically generating downloadable DMG files.

Packet Peeper’s source repository includes build scripts for creating both the application and the installer image, and continuous integration badges indicate automated build verification. Users can obtain the latest release from the GitHub releases page or compile the latest version from source.
