Supported platforms include Windows, Mac OS X, Linux, iOS, Android and Unity 3D.

ARToolKit has a C API, with portions in C++, Objective C and Java, depending on the platform.

A popular direct derivative of ARToolKit, includes complete bindings for C++, C# , Java and Flash AS3 (under the name )

Questions specific to ARToolKit and its applications should be tagged with this tag. If the question is more generally applicable to augmented reality development in general, use the tag.
