Clooca is a web-based tool for domain-specific modeling (DSM) aimed at improving software productivity and quality through the generation of source code from abstract models. It allows users to create and utilize domain-specific modeling languages (DSML) efficiently, significantly reducing development time, with reports indicating DSM can be 400% faster than traditional coding methods. The tool features components such as meta-modeling, code generation, and a cloud-based editor, enabling non-programmers to develop applications effectively.
