CyberChef is a great tool, thanks for sharing that! One of my main focuses was to create something a user could keep on their own system if they wish. Only coming back to the actual site when/if they want to get latest versions.

CyberChef runs locally as well. It even has a download link for that on the top left of the main page.

I was going to ask. Is a goal here for users to self/locally host if they like?

Yes, you can self host if you’d like as long as you don’t make it public. Be sure to get the latest version from GitHub periodically, or not. If it’s working no need to update.
