# Supported Platforms

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. Although Qt may be built on a range of platform-compiler combinations, only a subset of these are actively supported by Qt Software.

A more general overview of the platforms Qt runs on can be found on the Platform Notes page. Information about the compilers used on each platform can be found on the Compiler Notes page.

Qt Software's online Platform Support Policy for Qt describes the level of support you should expect for these platforms.

### Supported Features

Not all compilers used to build Qt are able to compile all modules. The following table shows the compiler support for five modules that are not uniformly available for all platforms and compilers.
