// HTML + JavaScript = 💜 <let/count=0> <button onClick() { count++ }> Clicked ${count} times </button>

Faster First Paint

Marko streams content to your users as soon as it's ready. No waiting for client side JavaScript bundles or data requests to start rendering.

HTML, assets, and images are loaded as soon as possible with asynchronous content loading in as it completes.

Granular by Design

Why ship entire Islands for a few grains of sand? Marko ships only what's needed, skipping hydration and stripping unused code at the sub-template level.

Lean by default. Fast by design. Unrivaled performance on any device or network.

Browsers and servers are built differently, shouldn't your code be too? Marko compiles your templates to perform their best with optimized, environment-specific output.

Faster loads. Smaller bundles. One seamless language.
