NerdVision is a modern production debugging tool that allows you to take a snapshot of your application state, including the stack and variables at runtime, giving you a high degree of visibility without making changes to source code, block the end-user experience, or introduce overhead. ‍ Speed and simplicity make NerdVision the perfect solution for developers to quickly test a hypothesis of what could be wrong with an application so you can dramatically reduce issue isolation time. NerdVision does not store any of your code; application code is cached in your browser to apply breakpoints on the correct line number - your code remains yours and on your device.
