Open Source Python Debuggers

A disassembler for the linux platform. Currently this supports x86 ELF files assumed to be written in C and output to intel- syntax assembly language; however the design is modular and replacements for any of these can be written.

httpdbg is a tool for Python developers to easily debug the HTTP(S) client requests in a Python program.

Pwndbg is a fast, simple and lightweight tool for modern debugging. It improves debugging experience with the strength of GDB for low-level software developers, hardware hackers, reverse engineers, and exploit developers. It provides features crucial for efficient debugging in the world of low-level programming. Vanilla GDB is terrible to use for reverse engineering and exploit development. Typing x/g30x $esp is not fun, and does not confer much information. The year is 2024 and GDB still lacks a real hexdump command! GDB's syntax is arcane and difficult to approach. Windbg users are completely lost when they occasionally need to bump into GDB.

A regex tool -- A Python GUI for creating, testing and debugging regular expressions for the Python programming language. Kodos utilizes the pyqt library for it's interface. Screenshots available on project homepage.

Obsolete. See http://www.ti.com/tool/msp430-gcc-opensource or upstream GNU tools. This is a port of the GNU C Compiler (GCC) and GNU Binutils (as, ld) for the embedded processor MSP430. Tools for debugging and download are provided (GDB, JTAG and BSL)

A RAD GUI Building IDE for wxPython.

The Virtual USB Analyzer is a graphical tool for browsing traces of captured USB data. It supports logs generated by Ellisys hardware analyzers and VMware's software analyzer, and Linux's usbmon.

Python framework to analyze Linux crash dumps programmatically from 'crash' and tools written using it. Documentation (a work in progress!) is available at: https://pykdump.readthedocs.io/en/latest/

Cinemagoer is a Python package useful to retrieve and manage the data of the IMDb movie database about movies, people, characters and companies. Platform-independent, it can retrieve data from both the IMDb's web server and a local copy of the whole db.

PyChecker is a static analysis tool for finding bugs in Python source code. It finds problems that are typically caught by a compiler for less dynamic languages, like C and C++. It is similar to lint.

Unfortunately this project has been suspended. If you wish to continue its development on your own, please feel free to contact me. UnPyc is a tool for disassembling, analyzing and decompiling Python's *.pyc and *.pyo files. UnPyc supports Python 2.5, 2.6.

Winpdb is a platform independent GPL Python debugger with support for multiple threads, namespace modification, embedded debugging, encrypted communication and is up to 20 times faster than pdb.

Clint is a testbed for static source-code checking techniques. It is currently designed to check C++ for common programmer errors and suggest improvements.

A replacement for the not so useful wingraph32 with uDraw, for the Interactive Disassembler (IDA).

An official experimental fork of Python's integrated development environment IDLE. Worthwhile and successful changes and additions will go back into the Python distribution's IDLE at some later stage. There is no spanish inquisition.

PyDbgExt is a WinDbg extention which support use Python script in WinDbg command line. Through this extention, we can call some predefine Python script to control the debug session, or directly evaluate expression or call other method.

l3lang is a persistent Python-like language and the l3gui provides a worksheet-like interface where computed values can be examined via simple selection and scripts can be assembled as structures.

99eyeballs is a tool that helps developers using Mac OS X Apple’s Cocoa frameworks find inconsistencies in the retain count of Objective-C cocoa objects.

Another Debugger for Python was written in Python3 using PySimpleGui and has a window showing your script and some buttons and another window showing variables and their values. The buttons entirely control ADP, they are accompanied by help buttons. ADP stores details of the path taken by your script and variables and their values in a SQLITE3 database. The current release supports LIVE running. A future release will support DEAD running. In DEAD runs you’ll be able to replay a LIVE run from the database recording, which means that you can start at any point and travel in either direction and the value of the variables will be those that were current at that point of time in the LIVE run. Imagine your script crashed and you can replay from there backwards, and see how you got there and the values the variables had. Extra functionality will allow running queries forwards and backwards.

It is a Process Monitoring Toolkit with the ability of Extend. E.g. You can use it to monitor a specified process. And set a triger like (over 50MB mem use) then do something like (report to DB).

Dionea (Dionea Musclipla, meaning Venus Fly Catcher)- an asynchronous thread-aware, peer-aware, and session-aware distributed debugger for Ruby and Python. A notable feature is to trace the sessions of the web applicaions using Rails and TurboGears.

ChatDBG is an AI-assisted debugging tool that integrates large language models into standard debuggers like pdb, lldb, and gdb. It allows developers to engage in a dialog with the debugger, asking open-ended questions about their program's behavior, and provides error diagnoses and suggested fixes.

Chisel is a collection of LLDB commands designed to assist you in the process of debugging iOS apps. All of the commands provided by Chisel come with verbose help. Be sure to read it when in doubt! You can add local, custom commands. There's also builtin support to make it super easy to specify the arguments and options that a command takes. See the border and pinvocation commands for example use. Developing commands, whether for local use or contributing to Chisel directly, both follow the same workflow. You can also inspect a specific command by passing its name as an argument to the help command (as with all other LLDB commands). There are many commands with compatibility with iOS/Mac. For a comprehensive overview of LLDB, and how Chisel complements it, read Ari Grant's Dancing in the Debugger, A Waltz with LLDB in issue 19 of objc.io.

CodeInvestigator is a tracing tool for Python programs. All the run time information is recorded. Read your code together with its run time details. Use it to visualize what happened when you program ran.

This is a command line tool that list all registered occurences of a DLL from the windows registry and allows to unregister them all with regsvr32.
