You can go to the "Visitors" list and from there you can see a summary of each visit and also view the recording.
userTrack is not free (open-source) but sold as a product for a one-time fee. As for the soure code: currently you get the original PHP backend code but only the bundled front-end code. I am also adding soon the option to download the original front-end code (TypeScript + ReactJS + MaterialUI).
I have thought about releasing userTrack as open-source, but I currently work full-time on it and I need to sustain myself, otherwise I couldn't spend the time to work on it. If I find a sustainable way to open-source it, I will.
Well, it was in my interest to share it, but I do think it's one of the best ways to improve user privacy while still being able to get valuable insights.
I'm by no means a UI or UX expert :)
