These utilities capture the precise state, inputs, and environment logs of your software to recreate complex failures exactly as they occurred. By turning intermittent bugs into repeating sequences, they allow you to step through historical execution paths until the root cause becomes clear. When selecting a tool, focus on the overhead it introduces to your runtime and how well it maps captured telemetry back to your specific source code.
