Our review
Pros	Free and open source with MIT licensing Supports Vulkan, Direct3D, OpenGL, and OpenGL ES Deep inspection for pipelines, resources, shaders, pixels, and meshes	Debugs CPU and GPU code simultaneously Supports CUDA C/C++, Fortran, remote sessions, and core dumps Inspects GPU state across multi-GPU debugging sessions
Cons	Focused on graphics APIs rather than general application debugging Nintendo Switch support is limited to authorized developers Source-level shader debugging support is specified for HLSL	Focused on NVIDIA GPU development Listed platform coverage centers on Linux Command-line workflow may not suit every development team
Our verdict	RenderDoc is a standalone, open-source graphics debugger for developers working with Vulkan, Direct3D 11, Direct3D 12, OpenGL, and OpenGL ES applications. Its core workflow captures a frame, replays it, and exposes the API usage and… Read the review →	CUDA-GDB is NVIDIA's open-source extension to the GNU Project Debugger for debugging CUDA applications on actual NVIDIA hardware. It is aimed at developers working with CUDA C/C++, CUDA Fortran, and mixed CPU/GPU programs who need one… Read the review →
