Our review
Pros	Native debugging for C, C++, Objective-C and Objective-C++ Remote, core-file and conditional-breakpoint support Integrates with Xcode, LLVM, Clang and VS Code via lldb-dap	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	Narrower language coverage than multi-language debuggers No time travel debugging Distributed through toolchains and IDEs rather than as a standalone commercial product	Focused on NVIDIA GPU development Listed platform coverage centers on Linux Command-line workflow may not suit every development team
Our verdict	LLDB is an open-source debugger from the LLVM Project for developers working with C, C++, Objective-C and Objective-C++. It supports macOS, iOS, tvOS, watchOS, Linux, FreeBSD, NetBSD, Windows and Android targets, with distributions… Read the review →	CUDA-GDB is NVIDIA's open-source extension to the GNU Project Debugger for debugging CUDA applications on actual NVIDIA hardware. It is aimed at developers working with CUDA C/C++, CUDA Fortran, and mixed CPU/GPU programs who need one… Read the review →
