Packet Sender is a 100% free, open-source network utility designed for sending and receiving network packets using major protocols like UDP, TCP, SSL, and DTLS. Developed by NagleCode, it serves as a highly accessible alternative to traditional command-line tools like netcat or hping. It offers a clean, intuitive Graphical User Interface (GUI) alongside a powerful command-line interface (CLI) for advanced automation. Core Features
Multi-Protocol Support: Send and receive raw traffic via UDP, TCP, SSL (encrypted TCP), and DTLS.
Built-in HTTP Client: Test API connections by quickly generating HTTP/HTTPS GET and POST requests.
Mixed Notation Payloads: Define network payloads using ASCII (e.g., hello world ) or Hexadecimal format (e.g., 68 65 6c 6c 6f), seamlessly converting between them.
Simultaneous Client/Server Operations: Act as a client to broadcast data, or host dedicated background servers on chosen ports to listen for inbound packets.
Panel Generator: Create custom control panels with single-button triggers that execute sequential strings of commands.
Packet Sender Cloud: Leverage a free companion cloud service to securely save, share, and synchronise packet configurations across different teams or devices. Common Use Cases
