GDB vs UDE Universal Debug Engine

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.
