Visualise Go runtime metrics in real time

Handle PHP errors, dump variables, execute PHP code remotely in Google Chrome

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.

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

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

Command line monitoring for goroutines

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.

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

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…

go-spew is a deep inspection library and debugging utility for Go. It functions as a data structure pretty printer that renders complex, nested types into human-readable strings with indentation and type information. The library provides specialized capabilities for visualizing internal program states, including the ability to dump data structures with pointer addresses and map keys. It includes a configuration system to adjust printing behavior, such as limiting recursion depth and setting indentation. The tool uses reflection-based type inspection and recursive tree traversal to handle nes

🔥 single-command flamegraph profiling 🔥

This project is a JavaScript logging utility and namespace-based debugger used for printing formatted, color-coded debug messages to the console in Node.js, web browsers, and Deno. It serves as a console output formatter and execution time profiler to help identify bugs and track program flow. The system manages debug visibility through named namespaces, allowing specific groups of messages to be enabled or disabled via environment variables. It distinguishes different modules in the output stream by assigning specific colors to these namespaces. The utility includes capabilities for measuri

Rdebug — Real Debugger

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
