Versions:
WinSocat 0.1.3, published by Firejox, is a lightweight Windows console utility that delivers the core functionality of the widely used Unix socat tool, enabling users to establish bidirectional data relays between two endpoints such as TCP sockets, named pipes, serial ports, or the standard input/output streams. Designed for network administrators, penetration testers, and developers who need to debug services, tunnel traffic, or quickly bridge disparate I/O channels without installing a full Unix compatibility layer, the program accepts a concise command-line syntax that specifies source and destination addresses along with optional protocol parameters, then transparently forwards every byte in both directions until either side closes the connection. Typical use cases include redirecting a local serial device to a remote TCP port, exposing an internal web service on an alternative interface, chaining multiple proxies for traffic analysis, or temporarily capturing and logging data flowing between legacy applications that only understand physical COM ports. Because the executable is self-contained and requires no installation privileges, it can be deployed on locked-down production servers or packed into automation scripts that must run immediately after deployment. The single published release, version 0.1.3, already implements the most commonly needed relay modes—TCP, TCP-listen, PIPE, COM, and STDIO—while keeping the binary footprint under a few hundred kilobytes, ensuring negligible runtime overhead even on older Windows versions. Users who previously resorted to heavier Cygwin or WSL workarounds can now obtain native performance and straightforward integration with PowerShell, CMD, or any scripting language capable of spawning console processes. WinSocat is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation of multiple applications.
