MSYS2

MSYS2 is a software distribution and building platform for Windows that provides a collection of tools and libraries for building, installing, and running native Windows software. It solves the problem of lacking a Unix-like development environment on Windows by offering a command line terminal (mintty), bash, version control systems like git and subversion, and build systems such as autotools, all based on a modified version of Cygwin. The main focus is on providing a build environment for native Windows software, keeping the Cygwin-using parts minimal.

The platform features a package management system called Pacman, familiar to Arch Linux users, which handles dependency resolution and system upgrades. It provides up-to-date native builds for GCC, mingw-w64, CPython, CMake, Meson, OpenSSL, FFmpeg, Rust, and Ruby, among others. The package repository contains over 3700 pre-built packages. MSYS2 supports both x86_64 and ARM64 architectures.

MSYS2 is intended for developers who need to build and run native Windows software using a Unix-like environment. It is available as a free download with an installer, and the package manager allows users to install and update software without a subscription or licensing model. There is no mention of a free plan, trial, or seat-based pricing; the software is distributed freely.
