Packet Sender

Packet Sender is a fantastic tool for anyone looking to test and secure their networks. Whether you're just getting started or you’re a seasoned pro, this app has something for everyone!

What is Packet Sender?

So, what makes Packet Sender stand out? For starters, it’s a free and open-source utility that works on multiple platforms like Windows, macOS, and various Linux distributions. You can send and receive TCP, UDP, SSL, as well as HTTP/HTTPS requests without breaking a sweat.

User-Friendly Interface

This app is designed with the Qt GUI framework, making it super user-friendly. It looks pretty similar on all major systems—just remember that the theme might change based on your settings. The main window has four key sections:

• The Upper Part: This area shows the packet name, destination address, port details, and associated data.


• The Upper Right Corner: Here you can edit fields for any saved packets.


• The Middle Section: This is where you check the status of your UDP, TCP, and SSL servers.


• The Lower Part: An IP toggle section lets you switch between IPv4 or IPv6 easily.

A Feature-Packed Tool

You might not notice at first glance how powerful Packet Sender really is! It can test network APIs through built-in clients for UDP, TCP, and SSL. Plus, it’s handy for malware analysis too.

Clever Connectivity Testing

If you're into testing network connectivity or firewall situations—like having two instances of Packet Sender chat with each other—you’re in luck! There’s also a quick GET/POST request button for testing HTTP control systems. And if you need to stress test devices by flooding the network with traffic? Yep, this tool can do that too!

Automation Made Easy

You can even automate your tests using command-line tools provided by the app. Now that's what I call versatile!
