/ CRC Card Designer

Design your class system

A Responsibility-Driven Design workbench. Paste a problem statement, harvest candidate classes and responsibilities, build a deck of CRC cards, and let the analyzer flag god objects, orphans, and tight coupling — then export a spec. New here? Start with the interactive RDD guide.
