I don't understand something. If you replay the events on an iframe of the real URL, each time I play the video you are hitting the site's real API? Like, if I watch the video where the user adds an item to it's cart, will the same item get added twice because I watched the video?

Yes, that is true and one of the biggest limitations of the system currently, this is why it's mostly suited for sites that don't load dynamic data (eg. landing pages, news sites, blogs, etc.)

Currently to avoid executing events twice, you can disable action replay on a specific button (it will show the click event but not replay the action).

I have always considered implementing or using something like rrweb but the performance and privacy implications are huge. Still a lot of customers would prefer that, mostly for the ecommerce cases you mentioned.
