If you are okay with single-threaded Linux native as a debug platform (i.e. you have a build that you reproduce bugs on) then you can probably use rr. undo.io has also been in the field for a long time. I hear they can also do multithreaded Linux native in some capacity as well. One of the people from undo frequently pops into time travel debugging threads when they appear, so they could give you more info if they drop by.

If you are on Windows, Microsoft has some form of time travel debugging, but I am pretty sure they do a instrumented emulator which is a 10-20x slowdown approach. I do not know of anything else on Windows.

The only efficient multithreaded time travel debugging I am aware of is all in the embedded field, so unlikely to be applicable. Most of the “multithreading” solutions otherwise available work by serializing your execution to a single thread, so they do not really count. Maybe there is something else out there, but not really sure.
