The HTML-First Reactive Framework
Build dynamic, reactive web applications using nothing but HTML attributes.
No build step. No virtual DOM. No transpiler. No JSX. Just HTML.
<script src="https://cdn.no-js.dev/"></script>
<div state="{ user: 'World' }">
<input model="user" placeholder="Enter name..." />
<h1 bind="'Hello, ' + user"></h1>
</div>Zero JavaScript written. Fully reactive. Two-way bound.
