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
  • Source-level debugging for C, C++, Rust, and assembler
  • RTOS awareness, instruction tracing, profiling, and coverage
  • Remote debugging, scripting, and power profiling support
Cons
  • Its primary focus is Windows rather than cross-platform debugging
