IBM® Rational® PurifyPlus™ is an award-winning dynamic software analysis solution designed to help developers write faster, more reliable code. It includes four capabilities packaged into a single product:

1. Memory debugging: pinpoints hard to find memory errors such as uninitialized memory access, buffer overflow and improper freeing of memory
2. Memory leak detection: identifies memory blocks that no longer have a valid pointer
3. Performance profiling: highlights application performance bottlenecks and improves application understanding with a graphical representation of function calls and
4. Code coverage: identifies untested code with line-level precision.

PurifyPlus is supported on Windows, Linux, Solaris, and AIX.
