Open Source Python Debuggers for Windows

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.

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) Obsolete. See http://www.ti.com/tool/msp430-gcc-opensource or upstream GNU tools.

Do you ever use print() or log() to debug your code? Of course you do. IceCream, or ic for short, makes print debugging a little sweeter. With arguments, ic() inspects itself and prints both its own arguments and the values of those arguments. Just give ic() a variable or expression and you're done. ic() returns its argument(s), so ic() can easily be inserted into pre-existing code. Additionally, ic()'s output can be entirely disabled, and later re-enabled, with ic.disable() and ic.enable() respectively. ic() continues to return its arguments when disabled, of course; no existing code with ic() breaks. To make ic() available in every file without needing to be imported in every file, you can install() it. ic() can also be imported in a manner that fails gracefully if IceCream isn't installed, like in production environments (i.e. not development).

Automatic Video Library Manager for TV shows. It watches for new episodes of your favorite shows, and when they are posted it does its magic. Select the show you want to grab, add it, and let SickChill handle the rest. See what SickChill holds in store for you. SickChill has a nice calendar that allows you to know what you will see next. It watches for new episodes of your favorite shows, and when they are posted it does its magic: automatic torrent/nzb searching, downloading, and processing at the qualities you want.

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.

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.

A RAD GUI Building IDE for wxPython.

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.

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

Oracle client side tracing and monitoring utility

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.

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.

This project contains some test scripts and software for Analog Devices' DSP chip emulators. This verifies whether a particular emulator is working correctly with a particular PC and target board.

A program to apply a link map to a Mac OS X crash log that came from a build without traceback tables. The output contains at least as much information as would the same crash log from a corresponding build with traceback tables.

File-Spector is a small, fast and easy to use binary file analyzer and Inspector. It allows the users to format a complete binary file structure and then use it to read any binary file that matches the specified format.

FlowLens MCP Server is an open-source tool designed to give AI-powered coding agents (like Claude Code, Cursor, GitHub Copilot / Codex, and others) full, replayable browser context to dramatically improve debugging, bug reporting, and regression testing for web applications. It works together with a companion browser extension: when a user reproduces a bug or a complicated UI interaction, the extension captures a rich session log, including screen/video recording, network traffic, console logs, DOM events, storage changes, and more, and exports it. The MCP server then loads this captured “flow” and exposes it to the AI agent via the Model Context Protocol (MCP), letting the agent examine, search, filter, and reason about the session just as a human developer would, without needing the agent to re-run the flow or rely on minimal reproduction data (logs, screenshots).

A Python programming environment providing memory sizing, profiling and analysis, and a specification language that can formally specify aspects of Python programs and generate tests and documentation from a common source.

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.

MSCViewer is a tool intended for debugging of control flows in concurrent, distributed systems. The tool loads logs generated by various entities in the system and visualize a sequence diagram chart for events and interactions. The diagram is fully interactive: entity can be added/removed from the diagram and shuffled; events can be filtered, searched, highlighted and annotated with comments. MSCViewer features integration with a Python interpreter which allows writing Python scripts interacting with the model. This powerful feature can be used to automate validatation of distributed control flows, integrate with graphing infrastructure, etc.

The Minions programming language makes it easy to write performant, highly parallel programs. Minions are especially good at web apps. Minions like the web.

Graphical debugger for programs that don't just follow one stream (e.g. threaded, web applications). Also allows debugging in headless computers, in distributed environments and for crashing applications.

OOpyREP is a python code generating filter and library. It reads a OpenOffice.org file and creates a python representation of the document structure as well as contents. The generated code uses the reportlab PDF library to render the document.

Orwell is a debugging engine written in Python and C++. It allows programatic debugging, meaning you can inherit from all of the debugger's classes and add your own functionality. It also aims to provide great support for breakpoints en masse.

Proctor is a tool for running unit tests for Python programs. It uses the standard unittest module, and provides a GUI and command line interface for finding and running all tests available in a package or set of packages.
