Visual Leak Detector

Enhanced Memory Leak Detection for Visual C++

Project maintained by KindDragon Hosted on GitHub Pages — Theme by mattgraham



Visual C++ provides built-in memory leak detection, but its capabilities are minimal at best. This memory leak detector was created as a free alternative to the built-in memory leak detector provided with Visual C++. Here are some of Visual Leak Detector’s features, none of which exist in the built-in detector:

Other after-market leak detectors for Visual C++ are already available. But most of the really popular ones, like Purify and BoundsChecker, are very expensive. A few free alternatives exist, but they’re often too intrusive, restrictive, or unreliable. Visual Leak Detector is currently the only freely available memory leak detector for Visual C++ that provides all of the above professional-level features packaged neatly in an easy-to-use library.

Visual Leak Detector is licensed free of charge as a service to the Windows developer community. If you find it to be useful and would like to just say “Thanks!”, or you think it stinks and would like to say “This thing sucks!”, please feel free to drop us a note. Or, if you’d prefer, you can contribute a small donation. Both are very appreciated.
