    This product is called Pernosco. It seems to be the commercial version of the rr reverse debugger. From their FAQ:

    This product is called Pernosco. It seems to be the commercial version of the rr reverse debugger. From their FAQ:

    rr is a free software project founded by Mozilla. rr is an enabling technology for Pernosco, and rr maintainers founded Pernosco. We aim to maintain rr as free software with at least its current level of functionality. Your program must be capable of running under rr to use Pernosco.

      Pernosco uses rr under the hood to record programs, and uses the approach from the video to build a queryable database of program state.
