MageBridge Mobile is a bridge between the Joomla! content management system and the Magento e-commerce platform. It allows businesses to use Magento for e-commerce functions like catalogs and carts, while using Joomla! for content like blogs, FAQs, and galleries. This provides a better experience for mobile users. MageBridge Mobile includes optimized themes for both Magento and Joomla! that improve speed and usability on mobile. It also replaces Magento's prototype JavaScript with jQuery to improve performance.
