Designite is a software design quality assessment tool that identifies design smells and metrics to help improve design quality. It detects abstraction, encapsulation, modularization, and hierarchy smells. It provides metrics on lines of code, classes, methods, violations, duplication, and dependencies. Designite integrates with SonarQube and offers academic licenses. It aims to help researchers study design quality and practitioners improve their code through smell detection and metrics analysis.

2. A brief history

3. Software design – important but inherently
complex
Real-life projects frequently suffer from poor
design quality and huge technical debt.

4. Seesaw game of software development
Technical Debt
Maintainability

5. Design smells
“Design smells are certain
structures in the design that
indicate violation of
fundamental design
principles and negatively
impact design quality”.
Identifying design smells and refactoring them could
lead us to a better design quality.
