Clash for Windows refers to a software application that allows users to set up and manage proxy servers on their Windows operating system. It is based on the Clash open-source project, which is a rule-based network tunneling tool written in Go. Clash for Windows provides a graphical user interface (GUI) for configuring proxy settings, managing rules, and controlling network traffic routing through different proxies. This tool is particularly useful for users who require flexibility in managing their internet traffic, such as bypassing regional restrictions, enhancing privacy, or improving network performance. Clash for Windows supports multiple proxy protocols, including Shadowsocks, V2Ray, and others, providing users with options to suit their specific needs for secure and efficient internet access.
