GNU Project
gnu.org is the official website of the GNU Project, a free software operating system founded by Richard Stallman in January 1984. The name is a recursive acronym: "GNU's Not Unix." GNU provides a complete Unix-like operating system composed entirely of free software that respects users' freedom—the right to run, study, modify, and redistribute software.
Key Projects
- GNU/Linux — The most widely used form of GNU, combining GNU software with the Linux kernel
- GCC — The GNU Compiler Collection, a cornerstone of open-source development
- GNU Emacs — Extensible, self-documenting text editor
- GNU Hurd — GNU's own microkernel, development started in 1990
The project is supported by the Free Software Foundation (FSF), which advocates for software freedom worldwide.
