We present the prototype release of the McXtrace Monte Carlo X-ray tracing software package. The package has been derived from the successful and proven McStas package for neutron ray tracing. The software package, realised as an open-source project, is aimed at simulating X-ray beam lines and instrumentation, in short to answer questions such as "Should we buy device X or Y to improve our data quality?" or "What are the optimal parameter settings of device Z?"

For starters, we discuss the differences between neutron and X-ray transport, how the two concepts are interlinked and how codes describing either may benefit from each other.

We show early results from a couple of simpler instrumental setups --- examples include a model of an laboratory SAXS-setup and a low-budget monochromatic beam line, and a discussion about the efficiency of the code. Furthermore, the open structure of the code is presented and how users may contribute, extend and benefit from it, for instance by interfacing to already existing, proven tools.
