Hyper.is, based on Electron, the open source framework for creating cross-platform desktop applications in HTML and JavaScript and developed by GitHub for its Atom text editor, powers a variety of well-known applications. Hyper.is, formerly known as HyperTerm and not to be confused with HyperTerminal, shares its name with several other projects. Hyper extensions consist of universal Node.js apps that get loaded by Electron and the render process. The extension system is based on the technologies used to build the application: React components and Redux actions.
