Live Recorder enables software reliability solutions across all phases of the software lifecycle. Record and replay program execution to quickly diagnose severe software failures in test or in production.

Find out more about Live Recorder

Fixing software failures is easy. Diagnosis is the hard bit. Reproducibility is the fundamental challenge in application debugging / resolution technique. There are times when it's simply impossible to replicate what the customer is trying to do.

Live Recorder solves this problem by recording the execution of your program as it fails - capturing the failure in the act. Live Recorder then allows you to replay that recording backwards and forwards to see what your program did and why. Magic!
