Hyper is a terminal emulator, a program that gives you a command-line interface to your operating system, built using the same web technologies that power websites: HTML, CSS, and JavaScript. The problem it aims to solve is that traditional terminal emulators are difficult to customize and extend. By building the terminal on web standards, Hyper makes it straightforward for developers to create plugins (extensions that add new features) and themes (which change the visual appearance) using familiar web development skills. The application is built on Electron, a framework that packages web applications into desktop apps, and uses React for its user interface. The terminal itself renders text using web rendering, which allows CSS to control fonts, colors, and layouts in ways that are impractical in conventional terminals. Plugins and themes are installed through a configuration file and discovered through an online store. A plugin can intercept keystrokes, modify the terminal's output, add new commands, or change how the app looks, all written in JavaScript. You would use Hyper if you prefer a terminal that you can deeply customize and extend using web development knowledge, or if you want a visually customizable workspace. You would also consider it if you want to write your own terminal extensions without learning a new plugin API. The tech stack is TypeScript and React running inside Electron on top of Node.js. It is available for macOS, Windows, and Linux and can be installed via direct download, Homebrew, Chocolatey, or the AUR package repository. The README is relatively brief, the main documentation is on the project's website at hyper.is.
