It was designed to support large, complex projects, written in any number of programming languages, primarily C/C++.

Instead, Qbs is provided with a set of modules written in a QML dialect and JavaScript that enable support for a variety of programming languages and tools.

Qbs currently provides modules supporting the Android SDK and NDK, C, C++, Java, NSIS, TypeScript, WiX, Xcode, and a variety of other tools.

Deserializing this file and utilizing the cached information allows Qbs to very quickly resolve the project, leading to near-instant incremental builds.

In contrast to make, Qbs does not rely on timestamps of files in the build directory, and tampering with its contents will not lead to targets being rebuilt unless the --check-outputs option is used.

Qbs' design aims to provide a much lower learning curve, better integration with IDEs, and a stable and powerful language with predictable behavior.
