# Flight Recorder

When an exception occurs the first thing developer needs to do is to diagnose and reproduce the erroneous scenario.  Such reproduction is time-consuming and often even impossible due to the specificity of the client’s environment. \
With RevDeBug you can cut this step completely! \
Simply go to Flight Recorder and replay the recorded code execution of exception with variable values just like in regular debugging.<br>
