microprofile is an embeddable profiler

A C++ micro-benchmarking framework

A C++ library for debugging purposes that can print any variable, even user-defined types.

Catch2 is a comprehensive framework for C++ software validation, providing an environment for unit testing, integration verification, and performance analysis. It enables developers to define and execute automated test suites and micro-benchmarks directly within their applications. The framework is distinguished by its header-only distribution, which allows for integration into existing build systems without requiring complex external dependencies. It utilizes a hierarchical section-based execution model that supports behavior-driven testing, allowing for shared setup and teardown logic acros

doctest is a unit testing framework and assertion library for C++ delivered as a single-header library. It provides a test runner with a command line interface to execute tests, filter test suites, and generate execution reports. The framework supports in-source unit testing and allows for the complete removal of testing logic from compiled binaries via preprocessor stripping to eliminate performance overhead in production environments. It also enables cross-binary test registry sharing, allowing one executable to utilize the test runner of another. Capabilities include parameterized testing

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

C++ mocking made easy. A simple yet very expressive, headers only library for c++ mocking.

DebugView++, collects, views, filters your application logs, and highlights information that is important to you!

This project is a comprehensive C++ unit testing framework designed to verify code logic and identify regressions through a suite of assertion macros, test fixtures, and execution runners. It automates the discovery and registration of test cases during static initialization, allowing developers to define isolated test environments that ensure repeatable and predictable conditions for every execution. The framework distinguishes itself through a sophisticated mock object library that enables the simulation of components and the enforcement of strict interaction requirements. By intercepting v

:pagewithcurl: Provides a log viewer for Laravel

Debug heap useful for tracking down memory errors.

Collection of self-contained header-only libraries for C++17

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

http-prompt is an interactive HTTP client and API testing CLI designed for constructing and debugging network requests to REST and GraphQL endpoints. It functions as a command-line request builder and a shell extension built on top of HTTPie. The tool provides an interactive shell interface featuring request autocomplete and real-time syntax highlighting for requests and responses. It incorporates stateful session management to maintain request history and session data across multiple commands. The project covers API request automation and REST API debugging, allowing users to send and verif
