About NetBSD

NetBSD is a free, fast, secure, and highly portable Unix-like Open Source operating system. It is available for a wide range of platforms, from large-scale servers and powerful desktop systems to handheld and embedded devices. Its clean design and advanced features make it excellent for use in both production and research environments, and the source code is freely available under a business-friendly license. NetBSD is developed and supported by a large and vibrant international community. Many applications are readily available through pkgsrc, the NetBSD Packages Collection.

About the NetBSD Foundation

The NetBSD Foundation was chartered in 1995, with the task of overseeing core NetBSD project services, promoting the project within industry and the open source community, and holding intellectual property rights on much of the NetBSD code base. Day-to-day operations of the project are handled by volunteers.

As a non-profit organization with no commercial backing, the NetBSD Foundation depends on donations from its users, and we would like to ask you to consider making a donation to the NetBSD Foundation in support of continuing production of our fine operating system. Your generous donation would be particularly welcome to help with ongoing upgrades and maintenance, as well as with operating expenses for the NetBSD Foundation.
