Programming is often a cycle between programming activities and understanding the results of those activities. Hence, modern development environments support many different tools to increase the speed of development, e.g., for refactoring or to visualize variable values or type information in a running program. However, current development environments provide these different tools in various ways, from wizards for refactorings with special preview pages to tooltips and watch views for showing specific information. In this paper, we present code portals as a generic technical concept to enable showing live and continuously updated information about the program and its state. We illustrate code portals on three different types of programming languages, procedural, functional and homoiconic. A qualitative user study shows that code portals and their applications are seen helpful by users. A video demonstration can be found at: https://goo.gl/PumhQR
