Have a look at https://rr-project.org/ (features and motivation are on that page). (Also mentioned in the article.)
It works on recorded state. It's not about executing a program again, it's about root causing a failure by going back in time after the failure happened. You can do things like start with a crash, retroactively set a break point and reverse run back in time until you hit it.
It's for real world applications. It was written specifically to debug Firefox, and has since been used for other applications of similar size.
It's basically GDB with extra commands, so very easy to use and learn if you know GDB. Highly recommend.
