Our review
Pros	Supports Ada, C, C++, Go, Rust, Fortran, Pascal, and assembly Includes remote debugging, core dumps, and simulator targets Offers reverse execution, replay, and program-state modification	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	No AI-assisted debugging features Remote debugging uses serial, socket, TCP, or UDP connections Its language coverage centers on native and systems-oriented development	Focused on NVIDIA GPU development Listed platform coverage centers on Linux Command-line workflow may not suit every development team
Our verdict	GDB is a free, open-source source-level debugger for examining programs while they run or after they crash. It is aimed at developers working across native applications, systems software, embedded or remote targets, and simulator… Read the review →	CUDA-GDB is NVIDIA's open-source extension to the GNU Project Debugger for debugging CUDA applications on actual NVIDIA hardware.
