A browser-based frontend/gui for GDB

.. figure:: screencast.gif
:alt: gdbgui


A modern, browser-based frontend to gdb (gnu debugger). Add breakpoints,
view stack traces, and more in C, C++, Go, and Rust! Simply run
``gdbgui`` from the terminal a new tab will open in your browser.



pip install gdbgui --upgrade




A new tab in your browser will open with gdbgui in it.


``gdbgui -h`` displays command line options, such as changing the port
or host ip. For any other questions feel free to email me or create an
issue in github.


``gdbgui`` has been tested to work in these environments. It may work in
other environments as well.

Python versions: 2.7, 3.3, 3.4, 3.5, pypy

Operating systems: Ubuntu 16.04

Browsers: Chrome, Firefox, Ubuntu Web Browser


``gdbgui`` was designed to be easily hackable and extendable. There is
no build system necessary to run or develop this app.

There are only three parts to gdb:

1. ``gdbgui.js``: There is just one JavaScript file, and that file
contains the majority of the app itself. It sends AJAX requests to
interact with gdb, then gets the response and updates the DOM as

2. ``gdbgui.jade``: HTML file that defines the frontend (Note: Jade/Pug
is a more concise form of html. Also note: jade has been renamed to
`pug <>`__, but the Python pypi package
still maintains the jade name. See demo
`here <>`__.)

3. ````: The backend consists of a single Python file, which
makes use of `pygdbmi <>`__ to
interact with a gdb subprocess, and
`Flask <>`__ to set up url routing and

To get started with development, set up a new virtual environment, then


git clone
cd gdbgui
pip install -r gdbgui/requirements.txt
python -m gdbgui.backend --debug


``python test`` runs unit tests located in
``gdbgui/tests/``. Add new tests there as necessary.


Contributions and bug fixes are welcome!

If you use this at your company or for your job, I would love to hear
from you -- send me an email and let me know.

Future Improvements

- Hover over a variable in source code to see its value
- Embed plotting tools to plot a variable's value over time
- Assign values to variables / memory addresses
- Embed a binary/decimal/hex calculator
