We are currently using PubPub (https://unjournal.pubpub.org/) as our main platform for hosting evaluations and ratings, manager summaries, and author responses. It offers flexibility, a good user-experience, and a range of features to help us integrate this work into the bibliometrics and archives (e.g., assigning DOIs). (See discussion of options in "Options for hosting reviews" doc.) We may find ways to use it in our submission platform and editorial management workflow as well; we are exploring this further.Some relevant private Gdocs (ask for access):
