Why OutSystems Created its own Framework
In essence, we preferred to build it ourselves, to ensure a perfect fit with the platform. We wanted to make sure we could change the code when required, that it had a perfect preview in the Development Environment and that we could implement an enterprise-grade responsive behavior and native-like mobile performance.
