Head JS :: The only script in your HEAD

Load scripts like images. Use HTML5 and CSS3 safely. Target CSS for different screens, paths, states and browsers. Make it the only script in your HEAD. A concise solution to universal issues.

With Head JS your scripts load like images – completely separated from the page rendering process. The page is ready sooner. Always. This is guaranteed even with a single combined JavaScript file. See it yourself:

Non-blocking loading is the key to fast pages. Moreover Head JS loads scripts in parallel no matter how many of them and what the browser is. The speed difference can be dramatic especially on the initial page load when the scripts are not yet in cache. It’s your crucial first impression.

Pages no longer “hang” and there is less or zero “flashing” between pages. User only cares when the page is ready. Unfortunately current networking tools don’t highlight this crucial point. They focus on the overall loading of assets instead.

Head JS can make your pages load 100% or even 400% faster. It can make the largest impact on client side optimization.
