A toolbar overlay for debugging Flask applications

Icecream is a Python debugging utility designed for inspecting variable values and execution flow during development. It provides a variable inspector that automatically labels values and attaches file and line number metadata to each output. The tool features a builtins injector that adds debugging functions to the global namespace, allowing for universal access across all project files without manual imports. It also includes an inline debugging tool that returns its arguments to the caller, enabling the insertion of inspection calls directly into active expressions without altering program

Hunter is a flexible code tracing toolkit.

He is like Batman, but for Node.js stack traces

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

Laravel Debugbar is a web-based debugging toolbar and application profiler for Laravel. It provides a visual interface to inspect database queries, logs, and performance metrics in real time to identify and resolve bugs during development. The tool features a database query monitor to capture SQL statements and timings, as well as a request inspector for analyzing route metadata, loaded views, and HTTP request data. It includes a profiler for measuring execution time and memory usage to identify bottlenecks in the request lifecycle. Its observability capabilities cover exception capture, app

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

Spyder is a scientific integrated development environment designed for scientific computing and interactive Python programming. It functions as a static analysis code editor and an interactive Python console, providing a specialized environment for writing and analyzing code for science and engineering. The platform distinguishes itself as an extensible development tool, utilizing a modular plugin architecture that allows for the addition of custom features or the embedding of core components into other software. It features a dedicated debugger and profiler for tracing code execution and mea

ExecuTorch is a lightweight C++ runtime for deploying PyTorch models on mobile, embedded, and edge hardware. It provides an ahead-of-time compilation pipeline that exports, quantizes, and lowers model graphs into compact serialized programs, then executes them through a minimal runtime with hardware acceleration and on-device large language model inference capabilities. The project distinguishes itself through a hardware accelerator delegate system that partitions model subgraphs and offloads computation to specialized backends including NPUs, GPUs, and DSPs from Apple, Arm, Intel, MediaTek,

Unreal.js is a JavaScript runtime and scripting layer for Unreal Engine that embeds the V8 engine to implement game logic and manage application state. It provides a bridge for writing high-level application behavior and actor control without modifying the core engine source code, as well as a framework for extending the Unreal Engine editor with custom interface elements. The project distinguishes itself through a V8-based integration that supports real-time code reloading and live iteration, allowing scripts to be updated without restarting the application. It includes a bidirectional commu

🐛 Memory leak testing for node.

Locus is a debugging module for node.js

This tool functions as a generator that maps dynamic framework methods and database model properties to static files, ensuring integrated development environments recognize runtime features. It acts as a static analysis helper by inspecting framework structures to provide accurate type hinting and autocompletion for core classes and container-bound objects. The project distinguishes itself by its ability to interrogate the dependency injection registry and scan runtime method registrations to document dynamically added functionality. It further differentiates by performing reflection-based in

Simple library that abstracts different metrics collectors. I find this necessary to have a consistent and simple metrics (functional) API that doesn't cause vendor lock-in.

PHP Console allows you to handle PHP errors & exceptions, dump variables, execute PHP code remotely and many other things using Google Chrome extension PHP Console and PhpConsole server library.

When your Laravel project grows, so do the Laravel views. Sometimes it might be hard to figure out, which part of the output HTML was rendered using which template. With this package, you can take a peek into your Laravel views and find out which template is responsible for which part of the…

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
