We present a toolkit called Velociraptor that can be used by compiler writers to quickly build compilers and other tools for arraybased languages. Velociraptor operates on its own unique intermediate representation (IR) designed to support a variety of arraybased languages. The toolkit also provides some novel analysis and transformations such as region detection and specialization, as well as a dynamic backend with CPU and GPU code generation. We discuss the components of the toolkit and also present case-studies illustrating the use of the toolkit.
