checkstyle
Checkstyle is a development tool to help programmers write Java code that is easy to read and adheres to a coding standard. Our utility automates the process of checking Java code to spare humans of this boring (but important) task. This makes it ideal for projects that want to enforce a coding standard. Each and every check also forces our users who are not familiar with these standards to read them and makes them think about why these standards exist.

International Catrobat Association
Computational thinking for all with free visual coding apps The Catrobat project develops useful frameworks to create games, animations, or apps easily within a short time. This set of mobile creativity tools for smartphones is inspired by the well-known Scratch framework by the Lifelong Kindergarten Group at the MIT Media Lab. The motivation behind the project is that programming is an important cultural technique on the same level as mathematics and physics, from a practical as well as from a philosophical point of view. Our aim thus is to popularize the skills needed to program from an early age in a fun and engaging way that will facilitate the spread of its adoption among young people all over the world.

MetaCall
When working with different technologies and developers of different programming languages, the productivity of the entire team worsens due to the lack of interoperability and communication between them. If the developers need two technologies which are written in different programming languages, for instance, a C/C++ library called from NodeJS, the team usually needs to port to one of the two languages or write a wrapper around them. Maintaining a port of a library or the plumbing code is frequently error-prone, time-consuming, and does not add any value to the final product.
