CUDA-GDB vs OllyDbg
Both stand on debuggers. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan LinuxSelf-hosted
Choose CUDA-GDB if you are working on CUDA applications in Linux or QNX and need to debug CPU and GPU code together. Consider another tool if your development or application environment depends on macOS, which is no longer supported by current CUDA Toolkit releases.
Visit CUDA-GDB Free plan Windows
Choose OllyDbg if you need a free Windows debugger for binary analysis and value its breakpoint, tracing, patching, and plugin options. Look elsewhere if you need ongoing development or a complete 64-bit version.

CUDA-GDB: what it does well
- Debugs CPU and GPU code together in one application.
- Supports CUDA C/C++ and Fortran applications.
- Provides source-level and GPU-assembly debugging.
- Supports conditional breakpoints and memory-access violation detection.
- Can debug kernels compiled for an architecture or at runtime with JIT.
What to know first
- Fortran debugging is limited to 64-bit Linux.
- CUDA Toolkit 11.0 and later no longer supports development or running applications on macOS.
- The macOS host version of cuda-gdb was dropped as of CUDA 12.5.
OllyDbg: what it does well
- Free to download and use, with free registration.
- Analyzes registers and recognizes common code structures and data.
- Can debug DLLs and attach to running programs.
- Supports conditional, logging, memory, and hardware breakpoints.
- Can save patches and write them back to executable files.
What to know first
- Development is frozen.
- The 64-bit version is incomplete.
- Does not work under Win32s.
- Registration is requested for permanent or commercial use.
