1. Interface Customization: Bootstrap Studio allows for extensive customization of the interface to tailor it to the user's preferences, such as custom themes and panel arrangement. In contrast, Pingendo has a more limited interface customization capability, providing a fixed layout that cannot be modified as extensively.

2. Component Libraries: Bootstrap Studio offers a vast library of pre-designed components and templates that users can drag and drop onto their canvas for quick website development. On the other hand, Pingendo provides a smaller selection of components and templates, requiring more manual design work from the user.

3. Code Editing: Bootstrap Studio allows users to edit the underlying code of their designs directly within the tool, providing a hybrid visual and code editing experience. Pingendo, however, focuses more on visual design, with limited options for direct code editing within the tool.

4. Collaboration Features: Bootstrap Studio offers collaboration features such as in-app comments and sharing capabilities to facilitate teamwork on web design projects. Pingendo lacks robust collaboration features, making it less suitable for collaborative design work.

5. Price Structure: Bootstrap Studio follows a paid license model with one-time purchase options for the software, providing access to all features and updates. In contrast, Pingendo offers a freemium model with basic features available for free but requiring a subscription for advanced functionalities.

6. Learning Curve: Bootstrap Studio is known for its ease of use, with drag-and-drop functionality and intuitive design features that make it beginner-friendly. Pingendo, while user-friendly, may have a steeper learning curve for users who are new to web design tools due to its slightly more complex interface and design process.

In Summary, Bootstrap Studio excels in interface customization, component libraries, code editing capabilities, collaboration features, price structure, and user-friendly design, whereas Pingendo offers unique strengths in its own limited interface customization, basic component libraries, visual design emphasis, free basic features, and possibly more challenging learning curve.
