LogRocket looks interesting and may be very helpful for debugging problems in production or optimizing performance. But FullStory or something like it fits my current needs better. I just want a video of real users interacting with the site to see where they get confused. And I don't want to spend a lot of time integrating code to get it to work. That is what FullStory is promising but I haven't tried it yet.
EDIT: They used FullStory (https://fullstory.com). I missed that when I read it the first time.
