Mongoose is an embedded networking library providing TCP/IP stacks, web server hosting, and IoT device connectivity. It enables microcontrollers and desktop systems to implement network protocols including HTTP, WebSocket, and MQTT. The project provides a bare-metal TCP/IP stack for environments without a native operating system and includes built-in TLS and ECC encryption to secure network traffic. It features a binary-embedded file system to serve web content directly from the executable and supports over-the-air firmware updates for managing device fleets. Additional capabilities cover as

Mayhem-Firmware is a custom firmware for the PortaPack add-on that transforms a HackRF software-defined radio into a standalone handheld device capable of receiving, transmitting, and analyzing radio signals across a wide frequency range. The firmware provides a complete operational environment with an event-driven touchscreen interface, a menu-driven application launcher, and a real-time sample streaming pipeline that connects the hardware abstraction layer to a suite of modular applications. All user data, including frequency presets, captures, and configuration files, are stored on a remova

superpowers-zh is a collection of tools designed to enhance AI coding agents through a workflow orchestrator, a prompt library for coding assistants, and a server framework for the Model Context Protocol. It provides a specialized set of technical prompts optimized for Chinese language environments and regional software development standards. The project distinguishes itself by offering localized coding prompt sets that apply regional technical documentation standards and code review cultures. It enables the deployment of prompt-based work methodologies and localized programming skills into A

Create React apps with no build configuration.

Removes default postcss config and instead will use postcss.config.js

Storybook is an integrated environment for developing, documenting, and testing user interface components. It provides a development workshop for building components in isolation from main application logic, alongside a testing tool for simulating viewports and analyzing accessibility. The project creates a living catalog of interface elements that generates interactive examples and technical documentation for component APIs. It includes a dedicated environment for visual regression testing to verify states and behaviors across different configurations and screen dimensions. The platform cov

This project is a configuration utility and JavaScript bundler manager designed to extend build scripts and override settings for Create React App applications. It functions as a tool for modifying Webpack configurations without requiring a permanent ejection from the managed build system. The utility allows for the customization of development and production build settings, enabling the use of custom build scripts to redefine project entry points. It provides mechanisms to modify the default build and development server settings to fit specific project requirements. Capability areas include

Vite is a frontend build toolchain that provides a unified development and production pipeline for modern web applications. It functions as a modular, environment-agnostic build engine that leverages native ES modules to serve source code directly to the browser, eliminating the need for expensive bundling during the development phase. By maintaining an environment-aware module graph, it supports concurrent development across client, server, and custom runtime environments. The project distinguishes itself through a high-performance development server that utilizes a hot module replacement pr

The documentation framework for Preact projects

preact-cli is a command line interface and build pipeline for initializing, developing, and deploying Preact applications. It functions as a project scaffolding tool that uses predefined templates to generate the necessary directory structures and boilerplate for new web applications. The tool provides specialized capabilities for creating progressive web apps by generating service workers and caching strategies for offline functionality. It also includes a static site pre-renderer that converts application routes into HTML files during the build process to improve search engine visibility an

nwb is a zero-configuration build toolchain, module bundler, and development server for JavaScript and JSX applications and libraries. It functions as a build system that automatically derives compiler and bundler settings from a project's installed dependencies to remove manual setup. The tool is distinguished by its ability to act as a library compiler, generating multiple distribution formats such as ESM and CJS from a single source for package manager compatibility. It also includes a dedicated headless browser test runner that executes unit tests with integrated watch mode and code cover
