H5Write and H5Build are two online applications used to create and author H5Engines.
H5Engines are powered by HTML5Alive® technology. HTML5Alive® is a development framework that enables the rapid, efficient creation of interactive and animated content.
H5Build is an online application for building complete interactive experiences with animation, including but not limited to games. H5Build animation is most efficient and effective when Adobe Illustrator is used to create and edit the SVG assets.
