The OpenBSD project produces a FREE, multi-platform 4.4BSD-based UNIX-like operating system. Our efforts emphasize portability, standardization, correctness, proactive security and integrated cryptography. As an example of the effect OpenBSD has, the popular OpenSSH software comes from OpenBSD.

OpenBSD is developed entirely by volunteers. The project's development environment and developer events are funded through contributions collected by The OpenBSD Foundation. Contributions ensure that OpenBSD will remain a vibrant and free operating system.

OpenBSD provide the best development platform possible. They provide full source access to developers and users, including the ability to look at CVS tree changes directly. Users can even look at source tree and changes directly on the web.

Integration of good code from any source with acceptable licenses. ISC or Berkeley style licences are preferred, the GPL is not accepted when adding new code, NDAs are never accepted. OpenBSD make available source code that anyone can use for ANY PURPOSE, with no restrictions. Strive to make our software robust and secure, and encourage companies to use whichever pieces they want to. There are commercial spin-offs of OpenBSD.

OpenBSD pay attention to security problems and fix them before anyone else does. Try to be the #1 most secure operating system.

Greater integration of cryptographic software. OpenBSD is developed and released from Canada and due to Canadian law it is legal to export crypto to the world (as researched by a Canadian individual and as documented in the Export Control list of Canada).

Track and implement standards (ANSI, POSIX, parts of X/Open, etc.) Work towards a very machine independent source tree. Support as many different systems and hardware as feasible.

Be as politics-free as possible; solutions should be decided on the basis of technical merit.

Focus on being developer-oriented in all senses, including holding developer-only events called hackathons. OpenBSD do not let serious problems sit unsolved.

OpenBSD make a release approximately every six months.
