Browser-based debugger for C, C++, go, rust, and more

gdbgui turns this

into this

gdbgui is a modern, free, browser-based frontend to gdb

designed to leverage gdb's latests updates and features, and inspired by the amazing Chrome and Firefox debuggers

Maximize Your Time

Stop searching for gdb commands, and starting intuitively understanding the full context of your program.

Stay on the Cutting Edge

gdbgui is compatible with the latest version of gdb

Easy Learning Curve

gdbgui is easy to get started with yet supports scripting, and has terminal access while keeping the user interface in lock step

View Call Stack

View the stack, threads, and send signals to the inferior process

Explore Variables

Explore local variables, or watch variables over time. Pretty-print even the most complex data structures.

Visualize Data Structures

Understand what your algorithm is doing by visualizing data structures. Watch your binary tree algorithm in action!

...and much more

gdbgui has a ton of features, many not found in any other command line or graphical debugger including reverse debugging, concurrent debugging, gdbserver compatibility, gdb process attachment, x/y plot of variables, serving remotely without high-bandwidth X Forwarding
