Edge Translate
A translation extension
Edge Translate is a simple and practical translation plugin that supports mainstream browsers such as Chrome, Firefox, and 360 Secure Browser. The main purpose of our plugin is to assist users in reading foreign literature. To this end, we have followed the principle of the user's reading experience first, and made the following efforts. We use the API provided by Google Translate to translate words and sentences, which guarantees the accuracy of translation results to a certain extent. We support the translation of wording in PDF files, which breaks the dyslexia of many users when reading PDF documents (due to the Firefox browser's bug, this feature is temporarily unavailable on Firefox browser). We chose the friendly side pop-up to show the translation results. The pop-up display bar will push the user reading content to avoid blocking the content from affecting the reading. Please refresh the page that needs to be translated after installation or update! -

Ember Simple Auth
A library for implementing authentication/authorization in Ember.js
Ember Simple Auth is a lightweight library for implementing authentication/authorization with Ember.js applications. It has minimal requirements with respect to application structure, routes etc. With its pluggable strategies it can support all kinds of authentication and authorization mechanisms. it maintains a client-side session and synchronizes its state across multiple tabs/windows of the application. it authenticates the session against the application's own server, external providers like Facebook etc. The session service is the main interface to the library. It provides methods for authenticating and invalidating the session as well as for setting and reading session data. The session store persists the session state so that it survives a page reload. It also synchronizes the session state across multiple tabs or windows of the application so that e.g. a logout in one tab or window also results in a logout in all other tabs or windows of the application. -

Exokit
Native VR/AR/XR engine for JavaScript
This project enables developers to build XR experiences using the same code that runs on the web. Exokit engine is written on top of Node and emulates a web browser, providing native hooks for WebGL, WebXR, WebAudio, and other APIs used in immersive experiences. The future is immersive. The web is the best application platform. Javascript is the best ecosystem. It's not possible to do both 2D and 3D well. We don't do 2D. We can use an external 2D browser. Exokit empowers and connect apps, even (especially) if they aren't designed to cooperate. Apps should run in "reality tabs", layers of reality that blend together. Exokit is a Javascript Node.js module. C++ bindings hook into WebGL, WebXR, Magic Leap, Leap Motion, and various other device APIs. Exokit runs on Windows, macOS, Linux (x64), Linux (ARM64), and Magic Leap (ARM64). -

FancySS
fancyss is a project for bypassing the Great Firewall (GFW)
Fancyss is a “scientific Internet access / bypassing censorship” toolkit targeted principally to Asus routers running AsusWRT or Merlin-based firmware. The project provides a plugin suite (with “software center” integration) so that home routers can run proxy or tunneling tools (e.g. V2Ray) to circumvent firewall or censorship (“GFW” in the Chinese context). Because it integrates into the router’s firmware environment, fancyss automates configuration, routing, and firewall rules to minimize manual tinkering. It supports multiple architectures and firmware versions, though some submodules or variants (e.g. “fancyss_hnd”) are optimized for specific chipsets. The project also maintains offline packages for constrained environments and hardware support lists. Many users adopt fancyss to turn relatively cheap consumer routers into censorship-resilient gateways, avoiding separate proxy appliances. -

Simple, semantic markup. Supported in all major browsers, horizontal/vertical slide and fade animations. Multiple slider support, Callback API, and more. Hardware accelerated touch swipe support. Custom navigation options, compatible with the latest version of jQuery. Display your products in a neatly designed, responsive slideshow within WooCommerce. FlexSlider was built to serve up the best responsive jQuery slider around. I had built a few implementations of responsive sliders on different client projects and noticed that there was a glaring hole for plugin support with the concept. I wanted to build a plugin that would serve the newest of beginners, while providing seasoned developers a tool they could use with confidence. What has come forth is this, FlexSlider. I plan to maintain this plugin and provide support to users implementing FlexSlider into their sites. Responsive web design can be tricky, but I hope that FlexSlider serves to uncomplicate the process, just a little bit. -

Flight
A component-based, event-driven JavaScript framework from Twitter
Flight is a lightweight, component-based JavaScript framework that maps behavior to DOM nodes. Twitter uses it for their web applications. By way of example, we've included a simple email client demo (browse the source) built over the Flight framework. There's also a flight implementation over on the todoMVC site. Flight uses jQuery and requires a module loader with support for AMD, like WebPack or Require.js. Please read the Flight documentation for installation instructions. Flight is distinct from existing frameworks in that it doesn't prescribe or provide any particular approach to rendering or providing data to a web application. It's agnostic to how requests are routed, which templating language you use or even if you render your HTML on the client or the server. While some web frameworks encourage developers to arrange their code around a prescribed model layer, Flight is organized around the existing DOM model with functionality mapped directly to DOM nodes. -

GitMCP
Turn any GitHub repository into an MCP documentation server for AI
GitMCP is an open source remote Model Context Protocol (MCP) server designed to transform GitHub repositories into structured documentation hubs that AI assistants can query directly. It enables developer-focused AI tools to access up-to-date project documentation and source code so that responses are grounded in real repository content rather than outdated training data. By exposing repository documentation and code through standardized MCP tools, GitMCP helps reduce incorrect or fabricated answers when AI systems assist with coding tasks. It can operate in repository-specific mode, where an AI assistant connects to a particular project, or in a generic mode that allows switching between multiple repositories dynamically. Its architecture retrieves documentation, analyzes code, and provides searchable access to repository information through semantic search and code analysis capabilities. -

Gitingest
Create prompt-friendly codebase digests from any Git repository URL
Gitingest is a developer utility that converts an entire Git repository into a structured, prompt-friendly text digest suitable for use with large language models. It analyzes a repository and produces a consolidated textual representation that includes the file structure and code content in an organized format. This makes it easier to provide meaningful code context when working with AI systems that require compact, readable inputs. Developers can generate these digests from either a local directory or a remote repository by supplying a repository path or URL. The generated output is optimized for prompt usage, helping AI models understand codebases more effectively without requiring manual file aggregation. In addition to producing the code digest, Gitingest also calculates statistics about the extracted content such as repository structure, total size of the extract, and token count. Gitingest can be used as a command line utility or integrated directly into Python applications. -

Gitrob
Scans GitHub repositories for potentially sensitive files
Gitrob is an open source reconnaissance tool designed to identify potentially sensitive files that have been committed to public GitHub repositories. It helps security professionals, researchers, and organizations detect accidental data exposure by scanning repositories associated with specific GitHub users or organizations. The tool works by cloning repositories and analyzing their commit history to search for files that match predefined signatures of sensitive data. These signatures are used to flag items such as credentials, private keys, configuration files, and other materials that may expose confidential information. By automatically inspecting repository histories, Gitrob simplifies the process of identifying security risks that might otherwise remain unnoticed in publicly accessible codebases. The results of the scan are presented through a built-in web interface that allows users to browse findings, review flagged files, and analyze potential leaks more efficiently. -

Google Closure Compiler
A JavaScript checker and optimizer
Closure Compiler is a production-grade JavaScript optimizer and checker that parses JS, analyzes it, removes dead code, rewrites and minifies what remains, and emits faster, smaller bundles. Beyond minification, it performs advanced optimizations such as inlining, property collapsing, type-guided rewrites, and cross-module motion, often yielding substantial load-time wins. It includes a strong static checker that validates syntax, variable references, and type annotations (Closure types or JSDoc), catching bugs early and enabling aggressive transformations safely. The ecosystem provides a Java implementation, npm/JS builds, and documentation for integrating in modern toolchains. Closure Compiler has been used extensively at scale within Google and by the broader community, proving its robustness on very large codebases. Companion repositories track npm packaging and a JS-only variant for environments where running Java is undesirable. -

Hakaton Starter
A boilerplate for Node.js web applications
A boilerplate for Node.js web applications. If you have attended any hackathons in the past, then you know how much time it takes to get a project started: decide on what to build, pick a programming language, pick a web framework, pick a CSS framework. A while later, you might have an initial project up on GitHub, and only then can other team members start contributing. Or how about doing something as simple as Sign in with Facebook authentication? You can spend hours on it if you are not familiar with how OAuth 2.0 works. When I started this project, my primary focus was on simplicity and ease of use. I also tried to make it as generic and reusable as possible to cover most use cases of hackathon web apps, without being too specific. In the worst case, you can use this as a learning guide for your projects, if for example you are only interested in Sign in with Google authentication and nothing else. -
