Open Source Python Debuggers - Page 2

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.

This project attempts to solve a long aching problem of a lack of a simple, yet powerful GUI for GDB. One that handles STL data types and allows easy extensibility. Requires: Python 2.7.x PySide (Qt python bindings: e.g. apt-get install python-pyside)

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.

FIDe is a software-based fault injector designed to validate Fault-Tolerant mechanisms and techniques used by applications. It was first used to measure database recovery coverage and costs, but can be used to test and validate ordinary applications.

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).

GObject reference counting debugger. A tool to help track down hard to find reference counting bugs in GObject, GTK and Gnome programs.

Game Conqueror HAS BEEN MOVED TO: http://code.google.com/p/scanmem/ Game Conqueror is a graphical game cheating tool (memory modifier) under Linux, whose main target is to provide functions and user-feelings of CheatEngine. Game Conqueror is written in PyGTK and using scanmem as its backend.

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.

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).

Goal of this project is to create a debugger for MIPS. Transition from python project to C after completion. Tailored for UIUC CS 232 course.

Mondo: Shared Library Monitor

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.

A microkernel operating system distribution offering (among other things) very low hardware requirements, full and easy portability and easy-readable source code.

Oracle client side tracing and monitoring utility

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.

PotatoFinder is a Windows Incident Correlation Engine developed by PotatoChimp Labs. It helps users investigate crashes, system instability, and unexpected behavior by reconstructing timelines of events and identifying likely root causes. PotatoFinder continuously monitors important system activity such as software installations, Windows Updates, process crashes, driver changes, service modifications, and other system events. The built-in Investigation Engine correlates events around an incident, calculates confidence scores, generates evidence for and against each possible cause, and reconstructs what changed before things broke. Historical fingerprinting allows similar incidents to be compared over time, helping users recognize recurring problems and successful fixes. Features include: • Timeline Reconstruction • Incident Correlation Engine • Historical Fingerprinting • Root Cause Analysis • Anomaly Detection • Exportable Reports • Dark Theme GUI with System Tray usage.

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.

Usually, coding a script involves writing the code and either debugging or running it several times, examining variables or output and fixing the code until the desired effect is achieved. With PyCodebug, you get to see the effects of the code during coding, which greatly reduces the time needed to write a script. ================================== Demo Video: http://youtu.be/a6nFo4y3kzo ================================== Requires: Python 2.7x PySide

Python Wrapper For Windows Debugging Engine

PySnooper is a simple yet powerful Python debugging utility. Just add a @pysnooper.snoop() decorator, and it logs line-by-line execution with timestamps and local variable tracking—saving you from inserting print() statements manually.
