Testimonials

I'm an rr developer, but my real job involves a lot of Gecko debugging. I find rr a great improvement over bare gdb and use it for almost all my Linux debugging tasks. It's an amazing tool!

rr has taken the application I work on from borderline-impossible to use inside a debugger to comically easy. I've got all my coworkers hooked on it. If you're using gdb, you should probably be using rr.

I was ecstatic when gdb gained reverse debugging abilities, but quickly had to realize it didn't work for me in practice because I was trying to debug something too big for it (Firefox). I've recently used rr to do some debugging on Firefox, and it didn't fail to deliver. While things like reverse-continue were relatively slow, having to wait for those was totally worth it if you look at the pain you'd have had to go through if you hadn't been able to reverse-continue in the first place. My only complaint about rr is that it didn't exist earlier!
