Flex
An in-app debugging and exploration toolset for iOS development, enabling real-time inspection and modification of app state.
What is Flex?
FLEX is an in-app debugging and exploration toolset for iOS development. It provides a toolbar that allows developers to inspect and modify nearly every piece of state in a running application, including views, objects, network requests, and file systems, all without needing an external debugger.
iOS developers and engineers who need real-time debugging capabilities directly on devices or simulators, particularly those working on complex applications requiring deep runtime inspection.
Developers choose FLEX because it runs entirely inside the app, eliminating the need for LLDB/Xcode connections or remote servers, and offers a comprehensive set of exploration tools that work on both simulators and physical devices.
