The Rigi plugin for SDL Trados Studio enables WYSIWYG localization of software strings in SDL Trados Studio. The texts of the web application are provided in Rigi XML or Rigi XLIFF files.
The previews are stored on the Rigi server with the project. Rigi provides various tools to capture HTML previews, such as Websnap, a Chrome extension and automation scripts. This is usually the responsibility of the development organization. However, in some projects the PM may coordinate capturing previews.
