Stetho is a debug bridge that connects Android applications to Chrome Developer Tools. It allows for the real-time inspection of network traffic, internal application state, and the user interface layout directly within a desktop browser. The project provides specialized inspectors for analyzing Android-specific components. This includes a network inspector for capturing HTTP requests and responses, an SQLite database browser for querying local storage, and a view hierarchy inspector for mapping UI elements and styles. Additional capabilities cover runtime execution via an embedded JavaScrip

DoraemonKit is a mobile frontend development toolset designed to optimize the lifecycle of web and hybrid mobile applications. It functions as a comprehensive suite of productivity tools, providing specialized utilities for mobile UI inspection, web view debugging, and on-device performance monitoring. The toolset distinguishes itself through several targeted simulation and interception capabilities. It includes a network traffic interceptor for mocking API responses without modifying source code, a device state simulator for overriding GPS coordinates, and a mobile web debugging bridge that

Workflow-kotlin is a cross-platform state management and UI binding framework for Kotlin that models application navigation, background tasks, and screen rendering through composable, hierarchical state machines. The architecture drives application behavior by flowing immutable data downward to declarative user interfaces and routing user interactions upward through named event handlers. The library includes multiplatform target support for compiling shared code across operating systems, along with asynchronous operation execution that handles background tasks safely outside render passes. I

django-debug-toolbar is a developer tool that provides a browser-based set of diagnostic panels for inspecting HTTP requests and responses within a Django web application. It serves as a server-side diagnostics tool and web framework development suite, allowing developers to profile and inspect request-response cycles. The tool focuses on Django application troubleshooting, database optimization, and general web development. It enables the analysis of SQL queries and database performance to identify slow calls and reduce the number of requests per page. The software includes capabilities for

backward-cpp is a C++ stack trace library and debugging utility designed to capture, resolve, and print detailed execution traces and crash reports. It functions as a crash reporter and call stack printer that translates raw memory addresses into human-readable function names, filenames, and line numbers. The project provides automated crash reporting by registering system handlers for fatal errors, such as segmentation faults, to automatically generate execution traces upon program failure. It distinguishes itself by extracting source file fragments from disk to display specific lines of cod

Seer is a graphical frontend for GDB that provides a visual interface for inspecting variables, managing breakpoints, and stepping through code. It functions as a low-level debugger visualizer with specialized tools for call stack inspection and register visualization. The project distinguishes itself by integrating low-level program analysis directly into the visual experience, featuring a synchronized assembly overlay that maps CPU registers and assembly instructions to source code lines. It also includes memory bug detection capabilities by randomizing the program starting address during t

A lightweight Neovim plugin for inserting structured console.* statements in JavaScript and TypeScript files.

gdbgui is a web-based graphical frontend and visualizer for the GNU Debugger. It serves as a compiled language debugger that provides source-level inspection for C, C++, Go, Rust, and Fortran. The project acts as a remote debugging interface, providing a secure web portal for connecting to and controlling GDB sessions over a network. It distinguishes itself by offering a browser-based environment to visualize call stacks and data structures for programs running via the GNU Debugger. The interface covers program execution control and breakpoint management, featuring graphical variable inspect

py-spy is a sampling profiler and process debugger for Python. It allows for the analysis of running processes to identify performance bottlenecks and diagnose hanging programs without requiring code changes or restarts. The tool operates by reading the memory of a running process from the outside, which enables non-invasive sampling and state collection without pausing execution. It can resolve binary symbols to capture performance data from native extensions written in compiled languages and generate visual flame graphs for both native extensions and subprocesses. The project provides capa

PySnooper is a diagnostic library for Python that tracks variable values and execution flow to provide a detailed history of program state. By applying decorators to functions, generators, or classes, it logs line-by-line execution and state changes without requiring manual print statements. The tool distinguishes itself through its ability to monitor nested function calls and concurrent operations in multi-threaded applications. It captures execution context by accessing the current stack frame, allowing for the inspection of local variables and the evaluation of arbitrary expressions during
