| Languages | It supports CUDA C/C++ and Fortran applications, with Fortran debugging limited to 64-bit Linux. | GDB supports Ada, Assembly, C, C++, D, Fortran, Go, Objective-C, OpenCL, Modula-2, Pascal, and Rust. |
| Purpose | CUDA-GDB is NVIDIA’s debugger for CUDA applications running on Linux and QNX. | GDB lets users inspect what another program is doing while it executes or after it crashes. |
| Remote debugging | The feature list includes remote debugging for x86 and ARM. | The gdbserver control program connects programs to a remote GDB through target remote or target extended-remote. |
| Support | NVIDIA directs users with CUDA Tools questions to [email protected]. | The project provides mailing lists for announcements, discussion, patches, bug reports, and testing. |

GDB
GDB is a free debugger for inspecting a program as it runs or after it crashes. It can launch programs, stop execution under specified conditions, examine the stopped state, and change program state for experimentation. A target can run on the same machine, remotely, or in a simulator. GDB runs on popular UNIX variants, Microsoft Windows, and macOS, and supports languages including C, C++, Rust, Go, Ada, Fortran, Assembly, and others. Debugging options include conditional and exception breakpoints, core dump debugging, and record-and-replay with forward and reverse execution on supported platforms. For remote debugging, gdbserver connects a program to GDB. The console interpreter and GDB/MI are available, while Python extensions and the Debugger Adapter Protocol require Python support at build time. GDB is part of the GNU Project and is free software under the GNU General Public License, which allows copying, adaptation, and redistribution with source access. Official releases are available from GNU and Sourceware, with signature verification through the GNU keyring. Version 18.1 was released on September 25, 2026.
