A modern, browser-based frontend to gdb (gnu debugger)

gdbgui is a browser-based frontend to gdb, the gnu debugger. You can add breakpoints, view stack traces, and more in C, C++, Go, and Rust!

It's perfect for beginners and experts. Simply run gdbgui from the terminal to start the gdbgui server, and a new tab will open in your browser.

gdbgui works by using gdb's machine interface. gdbgui runs gdb as a subprocess, then sends and reads machine interface data to create an interactive user interface. You can learn more about how it works here.


gdbgui is used by thousands of developers around the world including engineers at Google and college computer science course instructions. It even made its way into the Rust programming language's source code and appeared on episode 110 of C++ Weekly.

I've only used @grassfedcode's gdbgui for a couple of days, but wow, it's pretty awesome and so dead simple to get up an running.Lou

Seriously, great front-end to gdb for those of us who are not always using a full IDE. Great project.Jefferson

Where were you all my life? And why did I use DDD?Mario
