DLHub Gateway is just a copy of the official Jupyter Kernel Gateway with minor changes to make it more easy-to-use for DLHub.app users. The majority of the files in this repository is exactly an unchanged copy from jupyter/kernel_gateway repository. We have just changed few files to make it more accessible, especially for our Windows users.
DLHub.app is a web application which helps the users to design and work on deep learning projects using visual programming. The main idea is that the users can connect the online app to a Jupyter Kernel Gateway which is running locally on the user's machine; and then they run the visually programed codes on this gateway.
