laufey

laufey is a web embedded framework: build cross-platform desktop apps with web technologies and your choice of browser engine.

It is built around a small C ABI that separates the browser engine (the backend) from your application logic (the runtime). You write the runtime in Rust against one portable API; laufey ships prebuilt backends — Chromium via CEF, the system WebView, and an engine-free Winit windowing backend — and your app runs on any of them.

use laufey::{Value, Window};

fn main() {
    Window::new(800, 600)
        .title("My App")
        .bind("greet", |call| {
            let name = call
                .args
                .first()
                .and_then(|v| v.as_string())
                .unwrap_or("World");
            call.resolve(Value::String(format!("Hello, {name}!")));
        })
        .load("index.html");
}

laufey::main!(main);

Where to go next

• Architecture — how backends and runtimes fit together.
• C ABI — the laufey.h contract: entry points, the API table, and the value model. Read this if you’re implementing a backend or a binding.
• Backends — CEF, WebView, and Winit, and how they differ.
• The feature pages — windows, JavaScript interop, menus, dialogs, tray, notifications, and more — each with a usage example and its per-platform notes.
• Packaging & distribution — bundling, signing, and updates.
• Building — prerequisites and make targets.
