A HTML editor is a software (or hosted web application) that can be used by a third party (the user of the HTML editor) to create HTML documents that can be exported and used elsewhere. A web builder is a software (or hosted web application) that can be used by a third party (the user of the web builder) to create HTML documents that are hosted or dynamically generated under a top level domain chosen by the third party. The code base is the source code of the HTML editor or web builder, including the source code of publicly available plugins. No calls to layerJS can be made from the code base, but third party users can use layerJS in their websites that are built with these HTML editors or web builders.
