While Tracy can perform statistical analysis of sampled call stack data, just like other \emph{statistical profilers} (such as VTune, perf, or Very Sleepy), it mainly focuses on manual markup of the source code. Such markup allows frame-by-frame inspection of the program execution. For example, you will be able to see exactly which functions are called, how much time they require, and how do they interact with each other in a multi-threaded environment. In contrast, the statistical analysis may show you the hot spots in your code, but it cannot accurately pinpoint the underlying cause for semi-random frame stutter that may occur every couple of seconds.

Even though Tracy targets \emph{frame} profiling, with the emphasis on analysis of \emph{frame time} in real-time applications (i.e.~games), it does work with utilities that do not employ the concept of a frame. There's nothing that would prohibit the profiling of, for example, a compression tool or an event-driven UI application.
