About:
ucspi-tcp is a suite of command-line tools for creating TCP client-server applications. It provides a simple, reliable, and secure way to manage TCP connections, handling the complexities of socket programming. This allows developers to focus on application logic rather than low-level network details.

Key Features:

Simple command-line interface for TCP sockets
Includes tcpserver and tcpclient utilities
Handles connection management and forking
Security-conscious design by Daniel J. Bernstein

Use Cases:

Building custom network services and daemons
Creating simple TCP proxies or gateways
Rapid prototyping of network protocols

Alternatives:

netcat (nc) – netcat is a versatile networking tool, while ucspi-tcp provides a more structured framework for building persistent server applications.
socat – socat offers more complex bidirectional data relay capabilities, whereas ucspi-tcp focuses on a simpler client-server model.
