Xterm.js is a TypeScript terminal emulator frontend component that renders fully-featured terminals in the browser, supporting VT100/VT sequences, Unicode, mouse events, and optional GPU-accelerated WebGL rendering. It is a library (not a standalone terminal app) that connects to processes like bash via pty libraries such as node-pty, and powers VS Code, Hyper, and Tabby.

Use cases

• embed a terminal in a web-based IDE
• build a browser SSH client
• render terminal output in a web app
• share a terminal over the web
• add an integrated terminal to an Electron app
• build an interactive coding playground in the browser

When to choose

• you need a full terminal emulator UI inside a browser or Electron app
• you want a zero-dependency, well-documented component with addon support
• you need curses/tmux/vim compatibility and Unicode/IME support in the frontend

When to avoid

• you want a downloadable desktop terminal application
• you need the pty/shell backend itself - pair it with node-pty or similar
• you are not building a JavaScript/TypeScript frontend
