Qt is a commercial and open source licensed cross-platform application and UI framework. It is developed by The Qt Company, together with the Qt Project Community under an open source governance model.
Using Qt, you can write GUI applications once and deploy them across desktop, mobile and embedded operating systems without rewriting the source code.
Qt is supported on a variety of 32-bit and 64-bit platforms, and can usually be built on each platform with GCC, a vendor-supplied compiler, or a third party compiler as indicated in the overview below.
Open GL (ES) 2.0, DirectX 9 or 11 (with ANGLE), or an
alternative renderer
is required for
Qt Quick
2.
Widgets
can be used without hardware acceleration.
In Qt 5 all platforms are created using the
Qt Platform Abstraction
(QPA), which makes it easy to port Qt into a new operating system.
The following platforms are supported in Qt 5.15. For support information for prior Qt releases, please consult the relevant version in the
Qt Documentation Archives
.
Configurations in
bold
are
Reference Configurations
.
Note:
Support for specific configurations or operating system versions may end before the support for Qt 5.15 does. A subsequent patch release of Qt 5.15 may drop support for a configuration as a
reference configuration
or replace it with a currently-supported version.

If the browser supports WebAssembly then Qt should run.
Note:
Qt has a fixed WebGL requirement, also for apps that do not use WebGL directly. Browsers often blacklist WebGL for older/unsupported GPUs.

Reference Configurations
Reference configurations are the primary focus of development. They are subjected to unit test suite and other internal testing tools on a frequent basis (prior to new version releases, source tree branching, and at other significant period points in the development process). Errors or bugs discovered in these platforms are prioritized for correction. Significant errors discovered in tested configurations can impact release dates.
Any configurations not listed above are not actively tested by the Qt Project. However, Qt may run on configurations other than those actively tested on, and additional configurations may be raised to tested state, if sufficient effort is made to bring continuous integration to an acceptable state for that particular configuration. The reference configurations are subject to change during the lifetime of a Qt release.
The Qt Company provides support for the officially supported platforms and configurations. The Qt Company, Qt partners, open source projects and community users are also able to provide assistance with various different platforms and configurations.
You can download the Qt 5 installers and source packages from the
Downloads
page. For more information, visit the
Getting Started with Qt
page.
Note:
All the supported configurations are not provided as binary packages in the Qt installer. However, the intention is to provide the most widely-used reference configurations for the developer's convenience.
Exceptions
Individual modules might be available only on some platforms, or they might not support all configurations. For example, as Qt WebEngine has Chromium as a third-party dependency, platform or configuration limitations upstream also apply to Qt WebEngine.
The documentation for each module contains detailed information about any exceptions the module has from the general platform and configuration support as described on this page.
The deployment procedure for each platform is different and they are covered in greater detail in their platform pages. Meanwhile, there is a deployment article for summarizing the deployment procedure in general.
