Qwik Has a Free API: The Framework That Ships Zero JavaScript by Default

What if your web app loaded instantly because it sent zero JavaScript to the browser by default? That's Qwik.

What Is Qwik?

Qwik is built on resumability. Instead of hydrating your entire app on the client, Qwik serializes app state into HTML and only loads JavaScript when the user interacts with something.

import { component$, useSignal } from '@builder.io/qwik';

export default component$(() => {
  const count = useSignal(0);
  return (
    <div>
      <h1>Count: {count.value}</h1>
      <button onClick$={() => count.value++}>Increment</button>
    </div>
  );
});

The $ suffix tells the compiler: this code loads only on first click. Builder.io benchmark: Next.js 198KB/4.2s TTI vs Qwik 3.5KB/0.8s TTI. O(1) JavaScript — app size doesn't affect load time.

npm create qwik@latest
