It is available for download on Microsoft Windows and macOS based operating systems.
The version history of the HarmonyOS distributed operating system began with the public release of the HarmonyOS 1.0 for Honor Vision smart TVs on August 9, 2019. The first expanded commercial version of the Embedded, IoT AI, Edge computing based operating system, HarmonyOS 2.0, was released on June 2, 2021, for phones, tablets, smartwatches, smart speakers, routers, and internet of things. Beforehand, DevEco Studio, the HarmonyOS app development IDE, was released in September 2020 together with the HarmonyOS 2.0 Beta. HarmonyOS is developed by Huawei. New major releases are announced at the Huawei Developers Conference (HDC) in the fourth quarter of each year together with the first public beta version of the operating system's next major version. The next major stable version is then released in the third to fourth quarter of the following year.
OpenAtom OpenHarmony, or abbreviated as OpenHarmony (OHOS), is a family of open-source distributed operating systems based on HarmonyOS derived from LiteOS, donated the L0-L2 branch source code by Huawei to the OpenAtom Foundation. Similar to HarmonyOS, the open-source distributed operating system is designed with a layered architecture, which consists of four layers from the bottom to the top, i.e., the kernel layer, system service layer, framework layer, and application layer. It is also an extensive collection of free software, which can be used as an operating system or can be used in parts with other operating systems via Kernel Abstraction Layer subsystems.
The HarmonyOS App Pack or the App file, identified with the file extension ".app", serves as the file format used by the HarmonyOS operating system. It functions as a native HarmonyOS app for distribution and installation through Huawei AppGallery, or for distribution through Huawei Ability Gallery in respect of installation-free apps under both former classic dual-framework and current HarmonyOS NEXT system of unified OpenHarmony app framework. The App file is also used by a number of other open source HarmonyOS-based operating systems such as OpenHarmony and Oniro OS-based operating systems for distribution and installation of applications, video games and middleware. Including non OpenHarmony-based operating systems, such as GNU Linux-based Unity Operating System that supports the app file format.
HarmonyOS NEXT is a proprietary distributed operating system and an iteration of HarmonyOS, developed by Huawei to support only HarmonyOS native apps. The operating system is primarily aimed at software and hardware developers that deal directly with Huawei. It does not include Android's AOSP core and is incompatible with Android applications.
ArkGraphics 3D is an open source, 3D graphic stack developed by Huawei as a subset of Ark Engine for HarmonyOS and OpenAtom OpenHarmony. The engine layer includes two modules, such as 2D graphics library and 3D graphics engine with OpenGL with OpenGL Shading Language, WebGL and Vulkan as render service backend. The 2D graphics library provides the underlying API for 2D graphics rendering, and supports the underlying capabilities of graphics rendering and text rendering for ArkUI. AGP Engine as a component of ArkUI, it provides the 3D drawing capability of the system.
ArkUI is a declarative based user interface framework for building user interfaces on native HarmonyOS, OpenHarmony alongside Oniro OS applications developed by Huawei for the ArkTS and Cangjie programming language.
Ark Compiler, also known as ArkCompiler, is a unified compilation and runtime platform that supports joint compilation and running across programming languages and chip platforms, also operating systems of open-source OpenHarmony, Oniro OS, alongside proprietary HarmonyOS with single core system HarmonyOS NEXT included on native APP in Event-driven programming in a unified development environment and formerly built for Android-based EMUI for Huawei smartphones and tablets with HMS-enabled apk apps on AppGallery that improves app performance. It supports a variety of dynamic and static programming languages such as JS, TS, and ArkTS. It is the compilation and runtime base that enables OpenHarmony, Oniro OS alongside HarmonyOS NEXT to run on multiple device forms such as smart devices, mobile phones, PCs, tablets, TVs, automobiles, and wearables. ArkCompiler consists of two parts, compiler toolchain and runtime.
BiSheng Compiler is an open-source compiler toolchain developed by Huawei for general-purpose processor architectures, such as Kunpeng within HiSilicon domain. It is based on LLVM, and introduces and enhances multiple compilation optimization technologies and supports different programming languages, such as ArkTS, Cangjie, C, C++ and Fortran.
ArkTS is a high-level general-purpose, multi-paradigm, compiled, declarative programming language developed by Huawei which is a superset of open-source TypeScript, in turn a superset of JavaScript formerly used in July 2022 HarmonyOS 3.0 version, alongside its evolved percussor, extended TypeScript (eTS) built for HarmonyOS development as a shift towards Declarative programming. ArkTS compiles to machine code via its ahead-of-time compilation Ark Compiler. ArkTS was first released in September 30, 2021 on OpenHarmony, and the ArkTS toolchain has shipped in DevEco Studio since version 3.1, released in 2022. Since, OpenHarmony 4.0 release on October 26, 2023, ArkTS APIs has been added to the open source community to contribute.
ArkGraphics 2D is an open source 2D graphics stack for OpenHarmony-Oniro based and HarmonyOS operating systems. The engine layer includes two modules, such as 2D graphics library and 3D graphics engine with both OpenGL with OpenGL Shading Language and WebGL as render service backend. The 2D graphics library provides the underlying API for 2D graphics rendering, and supports the underlying capabilities of graphics rendering and text rendering for ArkUI.
MindSpore is a open-source software framework for deep learning, machine learning and artificial intelligence developed by Huawei.
HarmonyOS Kernel, sometimes referred to as the Harmony kernel, is a computer operating system (OS) kernel developed by Huawei since August 2023. It is used in the HarmonyOS NEXT version of the proprietary HarmonyOS operating system, replacing previous versions that utilized the AOSP compatibility layer, the Linux kernel, and the LiteOS kernel.
