Sharing a free web tool that diffs GPO backups, in case it's useful here
Figuring out what actually changed between two GPOs is a pain, so I made a web tool that does exactly that. You drop in 2 to 5 GPO backups and it shows the differences side by side.
It takes a backed-up GPO folder (or its ZIP), a Get-GPOReport XML, or a Get-GPOReport HTML, with search, collapsible categories, and export to CSV/Markdown/HTML for tickets or change docs.
It runs entirely in your browser and nothing gets uploaded.
It lives here, alongside an ADMX policy viewer I also run: https://admscope.com
Free, no login. If you hit a bug or have a feature you'd like to see, let me know.
Edit: You can also use it to just look inside a single backup - load one, remove the second slot, and you get a clean, searchable view of that GPO on its own.
