<h1>Welcome to Native Client</h1>

<div class="big-intro">
<p><strong>Native Client</strong> is a sandbox for running compiled C and C++ code in the browser efficiently
and securely, independent of the user's operating system. <strong>Portable Native Client</strong> extends
that technology with architecture independence, letting developers compile their code once to run
in any website and on any architecture.</p>

<p>In short, Native Client brings the <strong>performance</strong> and <strong>low-level control</strong>
of native code to modern web browsers, without sacrificing the <strong>security</strong> and
<strong>portability</strong> of the web. Watch the video below for an overview of Native Client, including
its goals, how it works, and how Portable Native Client lets developers run native compiled code on the web.</p>
