It exists so applications can ask one question, how to reach a network resource, without each application reimplementing environment-variable parsing, desktop proxy settings, PAC, WPAD, and network-change behavior. ### Project history The project originated before its GitHub repository; the 0.4.12 release notes on 2016-01-12 explicitly say development moved to `github.com/libproxy/libproxy`. The GitHub repository itself was created on 2015-04-17. The 0.4 series carried the traditional plugin-heavy proxy resolver stack, including desktop-environment integration and JavaScript engines for PAC. In 2023, the 0.5.0 release included a complete rewrite, and subsequent 0.5.x releases concentrated on platform behavior, Windows handling, XDG Desktop Portal support, PAC edge cases, packaging, and build cleanup. ### Adoption history libproxy spread through desktop and distribution ecosystems because proxy configuration is a cross-application problem. Its README lists support for Windows, Mac, and Linux/UNIX, and the repository displays Repology badges for Arch, Debian, Fedora, FreeBSD, Gentoo, Homebrew, MSYS2, openSUSE, Ubuntu, and others. ### How it is used Applications and libraries use libproxy to resolve the proxy or direct connection to use for a URL. Homebrew also installs the `proxy` command, giving users a small CLI surface around the same automatic proxy-resolution behavior. ### Why package nerds care libproxy is package-nerd significant because it is plumbing: when proxy auto-detection is wrong, every downloader, updater, package manager, and network client feels broken. Packaging it consistently lets desktop and CLI software share one resolver instead of each shipping a slightly different proxy stack. The 0.5 rewrite and later fixes show why distributions care about this library despite its small API. Build options, PAC JavaScript engines, desktop plugins, and platform-specific proxy stores all affect whether higher-level network software works behind corporate and campus proxies. ### Timeline - 2015-04-17: The GitHub repository was created. - 2016-01-12: Version 0.4.12 noted the move of development to GitHub. - 2020-12-04: Version 0.4.16 fixed CVE-2020-26154 and CVE-2020-25219 and updated PAC-related internals. - 2023-05-15: Version 0.5.0 shipped a complete rewrite. - 2024-04-25: Version 0.5.6 added XDG Desktop Portal proxy resolver support. ### Related projects - GNOME, KDE, XDG Desktop Portal, PAC and WPAD implementations, GLib/GIO networking, curl-like downloaders, and operating-system proxy settings are the related ecosystem. ### Sources -
