Open Source ChromeOS Debuggers

Code::Blocks is a free, open-source, cross-platform C, C++ and Fortran IDE built to meet the most demanding needs of its users. It is designed to be very extensible and fully configurable. Finally, an IDE with all the features you need, having a consistent look, feel and operation across platforms. Built around a plugin framework, Code::Blocks can be extended with plugins. Any kind of functionality can be added by installing/coding a plugin. For instance, compiling and debugging functionality is already provided by plugins! We hope you enjoy using Code::Blocks! The Code::Blocks Team

CxxTest is a unit testing framework for C++ that is similar in spirit to JUnit, CppUnit, and xUnit. CxxTest is easy to use because it does not require precompiling a CxxTest testing library, it employs no advanced features of C++ (e.g. RTTI) and it supports a very flexible form of test discovery.

wxHexEditor is another Hex Editor, build because of there is no good hex editor for Linux system, specially for big files. It supports files up to 2^64 bytes. Written with C++/wxWidgets GUI libs and can be used with other OS'es such Windows, Mac OS

DebugSwift is a comprehensive open-source toolkit aimed at iOS developers that streamlines and enhances the debugging experience for Swift-based applications by providing a rich set of interactive diagnostic tools. Designed to operate within the iOS environment (iOS 14+ and Swift 6+), it includes network and WebSocket inspectors for HTTP requests, detailed performance metrics (CPU, memory, FPS), and mechanisms to detect memory leaks and main thread violations in real time. The toolkit also provides developers with crash analysis features, console log monitoring, device and build information displays, and customizable debugging panels, all of which make it easier to troubleshoot edge cases and unexpected behavior. Interface inspection tools like grid overlays, 3D view hierarchy exploration, and touch indicators help visualize UI layouts and interactions directly on the device, giving developers immediate context into how their app behaves.

Jasmin is an interpreter for the x86 assembly language with a full-featured development environment aimed for educational purposes.

LiveDebugger is a browser-based debugging tool for Phoenix LiveView applications. It helps Elixir developers inspect LiveView behavior while the application is running in development. The tool can show the LiveComponents tree, view assigns, inspect elements, and trace callback execution. It is designed to make LiveView debugging more visual and easier to understand than relying only on logs or manual inspection. LiveDebugger can be installed as a development dependency and also offers browser DevTools extensions for Chrome and Firefox. Its main value is giving Phoenix LiveView teams a dedicated debugging experience for understanding component state, callbacks, and runtime behavior.

pyringe is a powerful Python process “syringe” that attaches to a running interpreter and lets you introspect—and even execute code inside—that live process. It blends debugger-style attachment (via gdb/ptrace techniques) with Python-aware helpers so you can inspect threads, frames, locals, and heap objects without restarting the target. This is invaluable for post-mortem diagnosis of production daemons where reproducing a bug in a dev shell is impractical. pyringe can inject arbitrary Python into the target process, enabling on-the-spot logging, state dumps, or gentle patching to keep a system limping along while you gather evidence. It’s also useful for forensic snapshots: enumerate objects of a certain type, find reference cycles, or measure memory pressure without pre-instrumentation. While powerful, it’s designed for careful, auditable use—showing exactly what code runs and where—so teams can regain visibility when black-box processes go sideways.

Portable emulator for Pokémon-Mini. Last version: 0.60 (16 June 2015) Check Wiki for platform dependencies and other information.

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.

GXemul is a full-system computer emulator, emulating processors (ARM, MIPS, M88K, PowerPC, and SuperH) and surrounding peripherals, in some cases well enough to let unmodified guest operating systems run as if they were running on real hardware.

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.

This sourceforge site for the project is now DEPRECATED and not updated. All current work and new releases are on github: https://github.com/OpenJML/OpenJML. The Java Modeling Language (JML) is a behavioral interface specification language that can be used to specify the behavior of Java modules (as in design by contract -- DBC). It has many tools to do assertion checking, unit testing, etc. The principal current tool of the project is OpenJML -- cf. https://www.openjml.org, with binary downloads from https://github.com/OpenJML/OpenJML/releases/latest

The ECLiPSe Constraint Logic Programming System is designed for solving combinatorial optimization problems, for the development of new constraint solver technology and their hybrids, and for the teaching of modelling, solving and search techniques.

The m6800 Simulator is a teaching tool to introduce students to microprocessors. It is based on a cut-down version of the M6800 chip, and a reduced instruction set. The simulator assembles and simulates execution of the users code on a GUI

the omega xvi project is a javascript debugger written in javascript. it can debug code, execute blocks of code or entire applications, as well as detect variables. because of its javascript nature, it can be run through a webpage, online.

LOG4PLSQL is a PLSQL framework for logging in all PLSQL code this project was born from the log4J spirit (and use it). You have the possibility to log apart from transaction and use all LOG4J feature.

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.

mspgcc4 is no longer supported. Please use the newer toolchain at the MSPGCC project. (This was a port of the GCC 4.x branch to the Texas Instruments MSP430 microcontroller core. It is based on the MSPGCC project that is stuck with GCC 3.2.3.)

kodeWeave is a realtime coding playground for HTML, CSS and Javascript. Similar to JSFiddle and JSBin, but kodeWeave was made to work offline but also as a prototyping application to build applications for desktop operating systems while on mobile devices. (PhoneGap Build is recommended for mobile devices) kodeWeave similar to jsfiddle, jsbin, dabblet, liveweave, codepen, cssdeck, cssdesk, tinkerbin, d3 playground, plunker and pastebin, but allows you to export your web app as a desktop and/or chrome application.
