Split-screen tutorials are an appealing and effective way for libraries to create online learning objects where learners interact with real-time Web content. Many libraries are using the University of Arizona's award-winning, open source platform, Guide on the Side. In 2016, Springshare released a proprietary alternative, LibWizard Tutorials. This article reviews the advantages and limitations of this kind of tutorial. It also examines the differences between each platform's distinctive characteristics. These platforms create similar split-screen tutorials, but have differences that affect diverse aspects of installation, administration, authoring and editing, student learning, data management, and accessibility. Libraries now have the opportunity to consider and compare alternative platforms, and decide which one is best suited to their needs, priorities, and resources.
