Undo Testimonials

"The Undo Debugger has helped us efficiently diagnose numerous challenging issues that would have taken much more time to resolve with gdb or other debuggers that are forward-looking with little or no reversibility. Even if you use it for only 5-10 issues per year, the time saved can pay for the cost of the license."

"The problem with traditional debugging is that you can see the failure but not why it happens. With Undo we’re able to debug the impossible problems and see what caused them. It is now one of our most important tools for these customer-critical situations using it for these problems has delivered real value and we can also see the productivity gains it provides for day-to-day debugging."
