Why Mobify.js?

Take control of your existing DOM on mobile and tablets. Move elements around, replace heavy images and scripts with low- bandwidth optimized versions.

Recreate brand new experiences using client-side templating when responsive falls short. As you make changes and add content your mobile site won’t fall out of sync.

Use Mobify.js to adapt your site to all devices, for both responsive sites and sites that want to go mobile fast with client-side templating.
