nteract is a desktop-based computing environment, which means that the application can take advantage of all the goodies that your operating system provides, like file search and click to open. nteract and the desktop belong together. nteract is built on top of a rich ecosystem of packages that allow developers to write software built on top of the notebook document format and the code execution protocol.
NOTE: This is only to provide appimages, I am not the developer.
