Open Source Debuggers

RenderDoc is a free MIT licensed stand-alone graphics debugger that allows quick and easy single-frame capture and detailed introspection of any application using Vulkan, D3D11, OpenGL & OpenGL ES or D3D12 across Windows 7 - 10, Linux, Android, Stadia, or Nintendo Switch™. I work on RenderDoc myself and you can always contact me with any problems or comments. I'll respond to you directly and personally, and I'm used to helping people with private or NDA'd projects. RenderDoc is 100% open source and development all happens on github. Check out the source and see how any feature is implemented, report a bug you've found, or request a new feature or improvement. Usability matters. Tools should have a low barrier to entry and be easy to use and understand. RenderDoc makes the process of getting started as smooth as possible, and simplifies common workflows. Support is distributed separately for authorized developers as part of the NintendoSDK.

BuGLe combines a graphical OpenGL debugger with a selection of filters on the OpenGL command stream. The debugger allows viewing of state, textures, framebuffers and shaders, while the filters allow for logging, error checking, video capture and more.

SPE is a python IDE with auto indentation&completion,call tips,syntax coloring&highlighting,uml viewer,class explorer,source index,todo list,pycrust shell,file browsers,drag&drop,Blender support.Spe ships with wxGlade,PyChecker and Kiki.

NativeViewer is a Visual Studio extension for visualization of OpenCV images stored in the cv::Mat class. A thumbnail image is shown during the debug when a variable is hovered by mouse with CTRL key pressed down. NativeViewer also formats the string displayed in the "Watch" window to express valuable cv::Mat information. The extension works only for native C++ code for both Win32 and x64 platforms. All Visual Studio .NET versions are supported. However, installation process differs for versions 2012, 2010 and pre-2010. Check the quick start guide for details: https://sourceforge.net/p/nativeviewer/wiki/QuickStartGuide Note that if you have Visual Studio 2012 or later, I recommend using Image Watch extension from Microsoft: https://visualstudiogallery.msdn.microsoft.com/e682d542-7ef3-402c-b857-bbfba714f78d

Printr Debugger is an Actionscript implementation of the "print_r" function from PHP. It has a lot of options, the results are presented in the Output Window or in the Printr Debugger Flash Panel. It offers remote inspection too.

CLIntercept inserts itself between a program and the OpenCL library. It can log OpenCL calls or errors, time expensive functions, modify the devices or extensions returned to the program, or track OpenCL objects. Tracking OpenCL objects also allows CLIntercept to detect some common programming errors, such as leaks, mismatched calls to retain/release, situations that are not thread safe, and errors with mapped images or buffers, including buffer overwrites. Any of these can be missed by the OpenCL implementation and led to incorrect behavior or even crash the system.

spyGLass is an OpenGL call tracer and debugger. It goes a step further than simply using ltrace because it knows what the arguments to the various gl* calls are, and it also knows about OpenGL's error flag.
