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
