Zipy is a proactive debugging tool which helps your developers monitor user sessions in your web app and track errors and exceptions occurring in the end user environment. This can be achieved by simply including a two line JavaScript SDK provided by Zipy in your web app. Once the installation is successful, Zipy starts recording the user actions, request-responses, console events, errors and exceptions on your app in the user environment, thus giving developers a way to proactively resolve issues on the user end.
