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

We extend the Eclipse IDE with tools for development in Haskell, a functional programming language, providing support for a wide range of tools (compilers, interpreters, doc tools etc.) in a coherent, convenient and configurable environment.

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.

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

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.

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

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.

ELFIO is a header-only C++ library intended for reading and generating files in the ELF binary format

CTrace is a multi-threaded trace debug library written in C. It provides a simple, fast, well documented trace utility for applications and as such is especially suitable for use in real-time embedded applications.

Jlint will check your Java code and find bugs, inconsistencies and synchronization problems by doing data flow analysis on the code and building the lock graph. Jlint is fast, easy to learn, and requires no changes in the class files to be checked.

IrcAppender is an appender for the Apache log4j system which forwards important logging event to an IRC channel. Output is controlled by the log4j configuration.

XTC4y is a collection of testing utilities for Java Code. It currently provides classes to instanciate an abstract class for testing the implemented methods, an invocation stack tracing the calls on an interface and a LogClassLoader. NOTE: DEVELOPMENT ST

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.

Jar Browser is a Java development utility for searching and browsing the contents of a set of jar and zip files. It supports searching for classes across multiple jars, plus a variety of other features. Great for solving CLASSPATH issues.

A Zilog Z80 simulator, debugger and profiler tailored for ZX Spectrum development (but generic enough to be used with other platforms)

Glassbox is an automated troubleshooting and monitoring agent for Java apps that diagnoses common problems with one-click. Drop in a .war file from http://www.glassbox.com and find out what's wrong with your existing web apps, without any code chang

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.

A java class assambler. This program assembles java byte code instructions for the JVM, like MASM for the CPU. Knowledge of the java byte code instruction is strongly required.

BT-Sim is a BlueTooth simulator on a HCI level. The project alows to develop and test BT applications without using real BT hardware. It works in particular with PalmSource's Palm OS Simulator.

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

Creates a function calls debug trace. Functions arguments, returned parameters and watched variables are reported in the same section. Traced variables can be processed by provided user functions for displaying purposes.

A C#, C++, Delphi, ActiveX ,javascript and Java trace framework and a trace viewer: Tail, outputDebugString, event log, Log4J, Log4Net, Microsoft EIF support and Pocket PC development (C++ and .NET)

WrapLog is a tiny Java logging package that can "wrap" around other logging packages, thus removing the need to stick to a certain one. This is particular useful for Java libraries that want to leave the choice for a logging packing to the client code.
