Packet Sender is a free, open-source cross-platform utility for sending and receiving TCP, UDP, SSL, and DTLS packets, plus HTTP/HTTPS requests, with a GUI, CLI, traffic generator, and panel generation. It runs on Windows, Mac, and Linux (built with Qt) and includes features like Wake-on-LAN, macros, smart responses, and Packet Sender Cloud for sharing packet definitions.

Use cases

• send test TCP or UDP packets to a device
• test network APIs with raw UDP/TCP/SSL clients
• test HTTP GET/POST requests with auth headers
• stress-test devices with intense traffic generation
• test firewall rules by having two senders talk to each other
• malware analysis with built-in packet servers
• send Wake-on-LAN magic packets
• build single-button control panels for AV systems

When to choose

• you need a free GUI tool to send/receive raw network packets across Windows, Mac, and Linux
• you want both a GUI and a CLI for interactive and scripted packet testing
• you need SSL/DTLS packet support or HTTP request testing in one tool
• you want to share packet definitions with teammates or customers via portable mode or cloud

When to avoid

• you need deep packet inspection or full traffic capture like Wireshark
• you require high-performance load testing at scale beyond stress-testing single devices
• you need a headless server-side network testing framework rather than a desktop utility
