Model Driven Engineering (MDE) is a new discipline in software engineering that advocates the massive use of models throughout the software development process. The emergence of this discipline has been accompanied by the prosperity of the tools that support it. On the long run, switching to MDE can be beneficial in case the process works, and the process itself depends on the tools. Since the transition is expensive, it is important to invest wisely, and choose the right tool. However, only recently tool creators have started considering metamodeling as an important issue in their list of concerns and university prototypes are sometimes difficult to download and test, so these tools remain little known overall and need to be listed. The aim of this article is to determine the strengths and weaknesses of the support that each of these MDE tools offer to the developer's tasks, in order to learn to identify the right tool that meets the specific needs of the software engineer, without recommending any particular tool or vendors: It will present a significant number of the most popular MDE tools, in order to keep this paper simple, list some criteria for comparing these tools and evaluate them against those criteria.
