Browser terminal rendering for web apps, powered by libghostty-vt in WASM, WebGPU with WebGL2 fallback, and TypeScript text shaping.

• Demo: https://restty.pages.dev/
• Canonical docs: https://restty.pages.dev/docs
• npm: https://www.npmjs.com/package/restty
• Issues: https://github.com/wiedymi/restty/issues

restty is early-release software. The high-level API is usable, but some APIs may still change while the developer experience settles.

npm i restty

<div id="terminal"></div>

import { Restty } from "restty";

const restty = new Restty({
  root: document.getElementById("terminal") as HTMLElement,
});

restty.connectPty("ws://localhost:8787/pty");

new Restty(...) creates the pane DOM, canvas, and hidden IME input for you.

• restty: primary API (Restty, createRestty, themes, fonts, PTY helpers, plugin types).
• restty/xterm: focused xterm.js-style compatibility wrapper.
• restty/headless: DOM-free WASM terminal core wrapper for replay, tests, and backend-owned sessions.
• restty/esm: standalone browser ESM bundle for script/CDN usage.
• restty/internal, restty/internal/runtime, restty/internal/surface: unstable advanced modules.

See the canonical API surface docs for the current method and export list.
