Packet Sender

The tool enables users to send and receive network packets over TCP, UDP, SSL, and DTLS on arbitrary ports. It includes a built‑in HTTP client for GET and POST requests with authentication headers, and a panel generator that creates single‑button interfaces to trigger predefined command sequences. Data can be entered in ASCII or hexadecimal, and macros allow dynamic content.

It is cross‑platform, running on Windows, macOS, and Linux, and provides both a graphical interface and a command‑line mode for automation and scripting. The command‑line version supports hotkeys and can be used for testing network APIs, firewall connectivity, or conducting stress‑testing with intense traffic generation.

Typical users include developers, network engineers, and security researchers who need a lightweight, open‑source utility for packet testing, HTTP request validation, or building simple control panels without ads or bundled software.
