I had a big OS migration project, where we moved all the RHEL machines to Ubuntu. We had a big set of Python scripts that would go out and query a bunch of databases and logging system to get the current state of the migration each day, but we published the results as a spreadsheet that was emailed rather than some website. It worked very well to get people data they needed and to put it in a form where they could ask their own questions of the data without talking to anyone else. It worked better than I expected, having not used excel for decades.
