An apparatus to identify and purge unused code may comprise a processor circuit on a device and a storage component configured to store a codebase including one or more portions of programming code. The apparatus may further comprise a sampling component, a profiling component, and a purge component. The sampling component may sample the codebase and generate one or more leads identifying portions of programming code from the codebase determined to be unused during a sampling period. The profiling component may receive the one or more leads and profile programming code identified therein during a profiling period and to identify portions of programming code determined to be unused during the profiling period. The purge component may receive identification of the portions of programming code determined to be unused during the profiling period and initiate a purging process thereon. Other embodiments are described and claimed.
