The [[Icon (computing)|icons]] in Haiku are named ''stippi'' and were designed by Stephan Aßmus.<ref>{{Cite web |title=Haiku®'s Icons - Haiku, Inc. |url=https://www.haiku-inc.org/trademarks/haiku_icons/ |access-date=2023-11-27 |website=www.haiku-inc.org}}</ref> Aßmus also created the Haiku Vector Icon Format (HVIF), a [[Vector graphics|vector storage format]] to store icons in Haiku, and is aimed at fast rendering and small file sizes.<ref>{{Cite web |title=Why Haiku Vector Icons are So Small |url=https://www.haiku-os.org/articles/2006-11-13_why_haiku_vector_icons_are_so_small/}}</ref>

== Software ==
[[Package manager|Package management]] is done by the graphical application HaikuDepot, and a command-line equivalent called <code>pkgman</code>.<ref name=":5">{{Cite web |title=Package Management Infrastructure — Haiku internals documentation |url=https://www.haiku-os.org/docs/develop/packages/Infrastructure.html |access-date=2023-11-26 |website=www.haiku-os.org}}</ref> Packages can also be activated by installing them from remote repositories with pkgman, or dropping them over a special ''packages'' directory.<ref name=":5" /> Haiku package management mounts activated packages over a read-only system directory. The Haiku package management system performs dependency solving with <code>libsolv</code> from the [[openSUSE]] project.{{Citation needed|date=November 2023}}

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 (text editor)|Pe]] and StyledEdit, an [[Internet Relay Chat|IRC]] client Vision, and a [[Bash (Unix shell)|Bash]]-based terminal emulator Terminal.<ref>{{Cite web |last=Wallen |first=Jack |date=2018-10-19 |title=To BeOS or not to BeOS, that is the Haiku |url=https://www.linux.com/topic/desktop/beos-or-not-beos-haiku/ |access-date=2023-11-26 |website=Linux.com |language=en-US}}</ref>

===Compatibility with BeOS===
Haiku R1 aims to be compatible with BeOS 5 at both the [[source compatible|source]] and binary level,<ref>{{Cite web |title=The Haiku Book: Application Level API Incompatibilities with BeOS |url=https://www.haiku-os.org/docs/api/compatibility.html |access-date=2023-11-26 |website=www.haiku-os.org}}</ref> allowing software written and [[compiler|compiled]] for BeOS to be compiled and run without modification on Haiku.<ref name=":3">{{Cite web |title=General FAQ |url=https://www.haiku-os.org/about/faq/ |access-date=2023-11-26 |website=Haiku Project |language=en}}</ref> The 64-bit version of Haiku, however, does not have BeOS compatibility at the binary level, but the API still does. (The same would apply to other non-IA32 ports, such as RISC-V.)<ref name=":3" /> Installation of these PKG format files are done using the PackageInstaller.<ref>{{Cite web |title=LegacyPackageInstaller |url=https://www.haiku-os.org/docs/userguide/en/applications/packageinstaller.html |access-date=2023-11-27 |website=www.haiku-os.org}}</ref>

==Reception==
In 2013 after the release of Haiku Alpha 4, [[Ars Technica]] reviewed the operating system and praised it for being fast, but ultimately stating that it "may not be much more than an interesting diversion, something to play with on a spare bit of hardware".<ref>{{Cite web |last=Reimer |first=Jeremy |date=2013-01-08 |title=1998's most intriguing OS, 15 years later: Hands-on with Haiku alpha 4 |url=https://arstechnica.com/gadgets/2013/01/not-quite-poetry-in-motion-ars-reviews-the-haiku-alpha-4-os/ |access-date=2023-11-26 |website=Ars Technica |language=en-us}}</ref> Haiku Beta 4 was reviewed by [[ZDNET]] in 2023 where it stated: "Haiku is for those who experienced either [[NeXT]] or [[AfterStep]] and want an operating system that looks and feels a bit old school but performs faster than any OS they've ever experienced." It further praised Haiku's kernel, file system, and object-oriented API.<ref name=":2"/>

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."<ref>{{Cite web|title=Explaining Why We Don't Endorse Other Systems|url=https://www.gnu.org/distros/common-distros.html|url-status=live|archive-url=https://web.archive.org/web/20180402035718/https://www.gnu.org/distros/common-distros.html|archive-date=April 2, 2018|publisher=[[Free Software Foundation]]}}</ref>
