## What it is
A web-based terminal emulator library that compiles Ghostty's native VT100 parser to WebAssembly and exposes an xterm.js-compatible API. It lets web apps render a real terminal with proper Unicode grapheme handling by swapping the import from @xterm/xterm to ghostty-web.

## Use cases
- embed a terminal emulator in a browser-based IDE or web app
- replace xterm.js with a more accurate VT100 implementation
- render complex scripts like Devanagari or Arabic correctly in a web terminal
- build a browser SSH or shell client
- add terminal output panels to agentic coding tools
- support XTPUSHSGR/XTPOPSGR escape sequences in a web terminal

## When to choose
- you need xterm.js API compatibility with better Unicode and escape-sequence fidelity
- you want the same battle-tested emulator code as native Ghostty in the browser
- you prefer a zero-runtime-dependency WASM bundle over a JS reimplementation

## When to avoid
- you need xterm.js addons or its broader ecosystem of plugins
- bundle size of ~400KB WASM is unacceptable for your app
- you rely on xterm.js features not yet implemented in ghostty-web

## Facets
- artifact type: library
