## What it is
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
