Winpdb Save

Fork of the official winpdb with improvements

Project README

Note from Philippe Fremy

The port of winpdb-reborn to Python 3 / WxPython 4 is unfortunately not working very well. So Winpdb for Python 3 does not really work. Feel free to submit Pull Requests to improve the situation. At the moment, this project is stopped.

Build Status Linux

Winpdb Reborn - A GPL Python Debugger, reborn from the unmaintained Winpdb

by Philippe Fremy as maintainer, and Nir Aides as initial author



Winpdb Reborn is a portable (Windows / Linux / macOS) standalone graphical debugger for Python. It focuses on making debugging easy and does not include any IDE features. It has very little dependencies (only wxPython for the GUI).


  • graphical interface with stack/variable inspection, breakpoints and more
  • breakpoints: on lines or functions, with possible conditions, load/save breakpoint info
  • multi-threaded debugging
  • smart handling of fork, follow parent or child
  • remote debugging: GUI on one computer, program to debug on another computer with encrypted communication
  • up to 20 times quicker than pdb, the default Python debugger (on which many other debuggers are built)
  • debug PyPy scripts

Note: The original Winpdb was no longer maintained since the v1.4.8 release in 2010. With the agreement of the author (Nir Aides), I (Philippe Fremy) am providing a maintained version with new functionality under the Winpdb Reborn name.


Platform supported:

  • Linux
  • Windows XP and above
  • macOS is probably working but not tested

To run Winpdb Reborn:

  • CPython 3.5 or above and wxPython 4

This version is for Python 3 only. A stable version of Winpdb for Python 2 is available on PyPi: and in the branch winpdb-reborn-python2 . You will need Python 2.7 and WxPython 3 to run it.

Note that running Winpdb with PyPy is possible, by launching with pypy and using the Winpdb GUI to connect to it.

Winpdb Reborn is NOT compatible with Jython or IronPython.

(not working yet until the new version is released).

The standard way to install Winpdb Reborn is with pip, as administrator/root::

# python -m pip install winpdb-reborn

You must also install the wxPython for your version of Python:

Winpdb Reborn is not packaged yet by any Linux distro. If your package manager proposes to install Winpdb, that’s the old unmaintained Winpdb which works neither with Python 2.7 nor with Python 3.

Additional installation methods

To install from a checkout or from an archive::

# python install -f

No install mode

If you don’t want to install Winpdb Reborn, you can still try it by calling it explicitly with your program to debug::

$ python /the/path/to/ 

Where do the files go ?

The setup script copies and modules to the Python site-packages folder. The scripts rpdb2 and winpdb are copied to the Python binaries (scripts) folder. On Linux, this folder is usually /usr/bin and is in the path by default. On Windows, this folder is %PYTHONHOME%\Scripts, where you should see a winpdb.exe and rpdb2.exe .


If you have installed Winpdb Reborn, the simplest way to launch it is::

$ python -m winpdb

or even::

$ winpdb

Find out about the other command-line options with –-help .


Use the -h or --help command-line flag for command-line help.

Inside Winpdb/Rpdb2 console, use the help command for detailed description of debugger commands.
