Vendors can pay for top positions in our rankings and for a place on other products' pages, and we may earn a commission when you click some links. Bought places stand at the number bought; this page and our disclosure say so. Paying vendors may get a fuller, more detailed review from our editors, and that review can change their score.

Our review
Pros
  • Combines user-mode and kernel-mode debugging for Windows code and drivers
  • Supports crash dumps, remote sessions, and configurable exception handling
  • Time Travel Debugging records and replays execution for deeper analysis
  • Free and open source with MIT licensing
  • Supports Vulkan, Direct3D, OpenGL, and OpenGL ES
  • Deep inspection for pipelines, resources, shaders, pixels, and meshes
Cons
  • Its primary focus is Windows rather than cross-platform debugging
