Merge with PythonDebuggingTools?

If you have anything to contribute -- e.g. configurations for editors, new debuggers, or opinion -- don't hesitate to edit or create pages.

Stand Alone Debuggers





Unix, Mac OS X

A visual, console-based, full-screen debugger, designed as a more comfortable drop-in replacement for pdb. (also supports IPython) PdbRcIdea All A .pdbrc for Pyhon's standard debugger, pdb, which allows you to run arbitrary Python commands on pdb startup.

HAP Python Remote Debugger


A python IDE with remote debugging capability. Winpdb and Rpdb2 Unix,Linux,Windows an advanced python debugger, with support for smart breakpoints, multiple threads, namespace modification, embedded debugging, encrypted communication and speed of up to 20 times that of pdb.

rpdb (offline)

Unix,Windows,Mac OS X

(predecessor of rpdb2 and winpdb) improves's usability and adds support for remote debugging, multiple threads debugging, post mortem of unhandled exceptions, and for debugging of embedded scripts.


Mac OS X, OS/2, Unix, VMS and Windows

both a CPYTHON and a JPYTHON(JYTHON) debugging framework which has been integrated inside Jedit as a standard jedit plugin.


Unix, Windows, Mac OS X

An expanded version of the pdb loosely based on the gdb command set. The debugger supports thread debugging, signal handling, non-interactive tracing, and much more. Xpdb Unix pdb extension with curses module that adds console window with source code.

trepan2, trepan3k

Unix, Windows, Mac OS X

A rewrite of pydb with closer compliance to gdb . In addition to the features of pydb, the debugger supports syntax coloring (via pygments), has extensive on-line help (in rendered reStructuredText), command completion, a smarter eval, debugger macros written in Python, and more.



DDD is a graphical front-end for command-line debuggers such as GDB, DBX, WDB, Ladebug, JDB, XDB, the Perl debugger, the bash debugger, GNU Make debugger, or the Python debugger. DDD displays data structures as graphs and plots. A deprecated version of pydb comes with this package. For GNU make debugging, use ddd-test5



Debugger for Python programs with a graphical user interface. It is inherited from "bdb" but uses a GUI and has some powerful features like object browser, windows for variables, classes, functions, exceptions, stack, conditional breakpoints, etc.



See DebuggingWithGdb Pyclewn *nix, Windows Pyclewn allows using Vim as a front end to a debugger. Pyclewn currently supports gdb and pdb.

IDE's with debug capabilities





Mac OS X, Linux, Windows

For teaching/learning programming. Focused on program runtime visualization. Provides stepping both in statements and expressions, no-hassle variables view, separate mode for explaining references etc.

Komodo IDE

Mac OS X, Linux, Windows


Mac OS X, Linux, Windows

PyCharm's integrated debugger works for Python and Jython, supports debugging of multiple threads, remote debugging, allows debugging Django, Google App Engine applications and unit tests. The debugger features various breakpoints, stepping modes, frames view, watches, evaluate expression tool and a debug console. Conditional and Exception breakpoint types are available for more precise control. Debug console allows executing any Python statements in the context of the process being debugged while stopped at a breakpoint.




Linux, Windows

An IDE tool used to edit, debug Python scripts, publish encrypted scripts, build a standalone executable file, and make installation in various forms(.msi, .tar.gz, .rpm, .zip, .tar.bz2). It includes an editor simulating Emacs python-mode, a GUI debugger simulating GDB, a project view used to manage scripts, modules, extensions, packages and platform specific data files.

Python Tools for Visual Studio


Supports Python (any implementation w/ sufficient sys.settrace capabilities) and IronPython .NET debugging. Includes MPI cluster debugging, breakpoints, conditional breakpoints, locals, watch, and immediate windows, step into/out/over, break on exception, and break on unhandled exception.

Special-purpose tools






Any Trace hook logger which outputs each thread in its own "swimlane" to make multithreaded analysis easier. Can also time calls (naively) and watch variables.


GoogleAppEngine + Firefox
