An unofficial Ghostty for the web.

libghostty-vt compiled to WebAssembly, drawn by a damage-aware WebGPU renderer, behind an xterm-shaped API. Open the Shell tab to type into it.

npm install ghostty-webgpu

The terminal could not start in this browser.

WebGPU, WebGL2, or Canvas2D is needed, along with WebAssembly.

Only what changed is drawn. The renderer tracks damage per cell, so an idle terminal costs nothing and a busy one costs only its busy rows.

Falls back on its own. WebGPU first, then WebGL2, then Canvas2D, with the same output. This page is drawing with a renderer it is still choosing.

Speaks xterm. Import ghostty-webgpu/xterm for the familiar constructor, options, and addon shape, or use the native API and keep PTY traffic as bytes end to end.
