PragmaTwice is an independent open-source publisher whose single public Windows utility, proxinject, occupies a narrow but technically valuable niche: transparently forcing almost any desktop process to route its traffic through an external SOCKS5 proxy without touching system-wide settings. The tool is typically deployed by privacy-minded users who want only their browser, game launcher, or chat client to exit through a remote server while leaving the rest of the OS on the direct connection; by developers who need to test geo-fenced APIs from a selected country IP without spinning up a full VM; and by penetration testers who must tunnel one offensive tool while keeping command-and-control traffic local. Written in modern C++, proxinject injects a minimalist DLL into the target executable at launch, hooks the Winsock layer, and redirects TCP and UDP flows to the configured proxy, all while exposing a straightforward CLI for process names, PIDs, or wildcards. Because it alters neither global registry keys nor proxy-auto-config files, the change is completely reversible once the process ends. PragmaTwice’s entire codebase is hosted on GitHub under a permissive license, encouraging community audit and fork. The publisher’s software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always fetch the latest upstream release, and can be installed individually or in batch alongside other applications.
