Haiku, originally OpenBeOS, is a free and open-source operating system for personal computers. It is a community-driven continuation of BeOS and aims to be binary-compatible with it, but is largely a reimplementation with the exception of certain components like the Deskbar. The Haiku project began in 2001, supported by the nonprofit Haiku Inc., and the operating system remains in Beta software.
In 2004, the project held its first North American developers' conference, WalterCon; it was also announced on this day that OpenBeOS was renamed to Haiku to avoid infringing on Palm's trademarks. The BeUnited.org nonprofit organization, which promoted open standards for BeOS-compatible operating system projects, announced that Haiku would be its "reference platform". In February 2007, the project held a Tech Talk at Googleplex, attended by ex-Be engineers as well as Jean-Louis Gassée who voiced his support for the project. There is also an annual conference, BeGeistert, held in Germany since 1998 when BeOS was active. Haiku Support Association (2014). "BeGeistert". Retrieved on October 24, 2014.HPS (2000-10-06). "BeOS Fans machen Dampf" (BeOS fans go for it). Heise online.
The first project by OpenBeOS was a community-created "stop-gap" update for BeOS 5.0.3 in 2002, featuring open source replacement for some BeOS components. The kernel of NewOS, for x86, SuperH, and PowerPC architectures was successfully forked that same year, and Haiku has been based on it since. The app_server window manager was completed in 2005. In July 2006, Haiku developer Stephan Aßmus introduced Icon-O-Matic, an icon editor, and a storage format (HVIF) with a rendering engine based on Anti-Grain Geometry. The PackageInstaller was created by Łukasz Zemczak at the 2007 Google Summer of Code. Java support was eventually added by a team from BeUnited who had ported it to BeOS, followed by WLAN from the FreeBSD stack. Alongside a port to GCC4, the first alpha release finally arrived after seven years of development. Initially targeting full BeOS 5 compatibility, a community poll was launched to redefine the future of Haiku beyond a free software refactoring of BeOS from the late 1990s. It was decided to add support for contemporary systems, protocols, hardware, web standards, and compatibility with FLOSS libraries. On October 27, 2009, Haiku obtained Qt4 support.
The WebPositive browser was first preloaded with Alpha2, replacing BeZillaBrowser. After this, much time was spent on building a package management system, which went live in September 2013. Beta1 arrived in 2018, and one of the most notable new features was the PackageFS and package installation through the HaikuDepot and pkgman; Beta1 was the first official Haiku release to support full package management.
Wine was first ported to Haiku in 2022.

The application program interface (API) is based on that of BeOS, which is divided into a number of "kits" which collect related classes together and bear some relation to the library which contains the supporting code. In 2007, Access Co Ltd, the owners of Be, Inc's intellectual property, released the text of this ( BeBook) under a Creative Commons licence. The boot loader is File system agnostic and can also Chain loading GRUB, LILO and NTLDR.
Since the Beta1 release, Haiku's memory management includes ASLR, DEP, and SMAP.]] Graphics operations and window management is handled by the app_server protocol. VESA is used as a fallback video output mode. Haiku is POSIX compatible and has translation layers for X11 and Wayland.
The icons in Haiku are named stippi and were designed by Stephan Aßmus. Aßmus also created the Haiku Vector Icon Format (HVIF), a Vector graphics to store icons in Haiku, and is aimed at fast rendering and small file sizes.
It comes with a number of preloaded applications, such as a WebKit-based web browser WebPositive, a document reader BePDF, a simple web server PoorMan, text editors Pe and StyledEdit, an IRC client Vision, and a Bash-based terminal emulator Terminal.
As of 2018, the Free Software Foundation has included Haiku in a list of non-endorsed operating systems because: "Haiku includes some software that you're not allowed to modify. It also includes nonfree firmware blobs."
