What is Outsystems UI classified as?

OutSystems UI is classified as a framework because it provides a structured environment with pre-defined components and patterns used for building web applications. A framework typically offers a set of tools, conventions, and best practices that help developers streamline the process of application development. In the context of OutSystems, it enables developers to create user interfaces efficiently while ensuring consistency and adherence to design standards.

While the term "widget" refers to individual components or building blocks in a user interface, OutSystems UI encompasses not just single components but a comprehensive system for constructing UI elements. Therefore, it is more than just a collection of widgets, as it provides a broader framework that unites these elements.

Similarly, "library" usually refers to a collection of reusable code or functions, often focusing on specific tasks rather than providing an entire system for application structure, which again underscores why OutSystems UI is better categorized as a framework.

As for "application," this term describes the end product that a developer builds using various tools and frameworks, including OutSystems UI, rather than the framework itself. Hence, "framework" is the most accurate classification for OutSystems UI, aligning with its purpose and functionality in the development process.
