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

An lldb plugin for Node.js and V8, which enables inspection of JavaScript states for insights into Node.js processes and their core dumps.

This project is a suite of runtime diagnostic tools designed to detect memory leaks, concurrency races, and language-specification violations during software execution. It provides a collection of dynamic analysis tools that identify addressability issues, uninitialized memory usage, and memory safety bugs in applications. The toolset includes a thread safety analyzer to identify data races and deadlocks in concurrent code, as well as an undefined behavior sanitizer to detect operations that violate language specifications. The system covers broad capabilities in memory safety monitoring and

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.

Scalene is a high-performance diagnostic utility designed to measure resource consumption during the execution of Python applications. It functions as a line-level monitor, providing granular insights that pinpoint the specific source code responsible for performance overhead. The tool distinguishes itself through statistical profiling that captures stack traces and resource usage without requiring manual instrumentation of the source code. It tracks CPU, GPU, and memory consumption by intercepting library-level calls and hardware driver commands, allowing for the analysis of both managed and

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

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

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,

:whitecheckmark: A Go library for email verification without sending any emails.

Rainfrog is a terminal-based database client that connects to multiple database engines, combining schema browsing, interactive SQL query execution, and inline data editing into a single terminal interface. It provides a tree navigator for exploring tables, columns, and indexes, and an inline cell editor that automatically constructs and executes the necessary UPDATE statements when a cell value is changed. The application also supports modal Vim-style keyboard shortcuts for cursor movement and editing, making it usable entirely from the keyboard. Query results are fetched in chunks and pagin

electron-vite is a build system and multi-process bundle orchestrator that uses Vite to compile and bundle the main, preload, and renderer processes for Electron applications. It functions as a desktop application scaffolder, providing templates to integrate various frontend frameworks into a standardized project structure. The project distinguishes itself through integrated source code protection, utilizing a V8 bytecode obfuscator to compile JavaScript into bytecode and obfuscate strings to prevent reverse engineering. It also manages complex desktop architectures by isolating bundles and s
