Welcome to 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 vivid international community. Many applications are readily available through pkgsrc, the NetBSD Packages Collection. » Learn more

[Fundraising Meter]

NetBSD 5.0 features greatly improved performance and scalability on modern multiprocessor (SMP) and multi-core systems. Multi-threaded applications can now efficiently make use of more than one CPU or core, and system performance is much better under I/O and network load.

In addition to scalability and performance improvements, a significant number of major features have been added. Some highlights are: a preview of metadata journaling for FFS file systems (known as WAPBL), the jemalloc memory allocator, X.Org instead of XFree86 on a number of ports, the Power Management Framework, ACPI suspend/resume support on many laptops, write support for UDF file systems, the Automated Testing Framework, the Runnable Userspace Meta Program framework, Xen 3.3 support for both i386 and amd64, POSIX message queues and asynchronous I/O, and many new hardware device drivers. » Full 5.0 Release Notes

A list of download sites providing FTP, AnonCVS, and other services may be found at NetBSD mirror sites page. We encourage users who wish to install via ISO images to download via BitTorrent by using the torrent files supplied in the ISO image area.

Your donation to the NetBSD Foundation allows the project to make major improvements to the code base. With work having begun on NetBSD 6.0, we announce the 2009 Fund Drive, targeting 60,000 USD by the end of the year. » Donations Page
