SwitchyOmega
Manage and switch between multiple proxies quickly and easily
Manage and switch between multiple proxies quickly & easily. The project is available as a Chromium Extension. You can try it on Chrome Web Store, or grab a packaged extension file (CRX) for offline installation on the Releases page. This project contains a PAC generating module called omega-pac, which handles the profiles model and compile profiles into PAC scripts. This module is standalone and can be published to npm when the documentation is ready. The folder omega-target contains browser-independent logic for managing the options and applying profiles. Every public method is well documented in the comments. Functions related to browser are not included, and shall be implemented in subclasses of the omega-target classes. omega-web is a web-based configuration interface for various options and profiles. The interface works great with omega-target as the back-end. -

Dispatch-Proxy
Combine internet connections, increase your download speed
dispatch-proxy is a Node.js tool that exposes a local proxy and distributes outgoing connections across multiple network interfaces to combine bandwidth for parallel transfers. Instead of trying to accelerate a single TCP flow, it improves aggregate throughput by load-balancing many connections—useful for download managers, package managers, or browsers that open multiple requests at once. It can bind new outbound sockets to different interfaces, letting a machine take advantage of Wi-Fi and Ethernet (or multiple uplinks) simultaneously. The utility runs as a simple proxy endpoint, so existing applications can benefit without code changes by pointing their traffic to it. Configuration is intentionally straightforward, making it easy to test with real-world workloads and see the effect on multi-connection downloads. While it won’t speed a single large stream, it’s a practical way to squeeze more total bandwidth out of multiple links in everyday use. -

Badges
Readme Badges – Gotta catch 'em all
Badges is a utility / site that generates small status badge images for open-source projects (for example, build status, coverage, downloads, version). It allows projects to easily embed dynamic badges in their README or documentation that reflect project metadata or external service metrics. The badges system supports different styles, icons, and dynamic links, making them visually consistent and informative. It abstracts the generation of badge SVGs so the end user doesn’t need to manually create or update image files. The project also supports caching, HTTP APIs, and format options (e.g. to serve badges dynamically or with query parameters). It is used by many open source repos to display real-time project metrics in documentation pages. -

Card
Make your credit card form better in one line of code
Card will take any credit card form and make it the best part of the checkout process (without you changing anything). Everything is created with pure CSS, HTML, and Javascript, no images required. To use, you'll need to include the Card JavaScript files into your HTML, no CSS link is necessary as the JavaScript file does this for you. You can find the necessary file at /dist/card.js and include it in your HTML like so. Once you've included those files, you can initialize Card. Card can be used in forms where you have multiple inputs that render to a single field (i.e. you have a first and last name input). To use Card with this functionality, just pass in a selector that selects the fields in the correct order. Card renders with default placeholders for card name, number, expiry, and cvc. To override these placeholders, you can pass in a placeholders object. -

PlatformIO Atom IDE Terminal
A terminal package for Atom, complete with themes, API and more
The PlatformIO Atom IDE Terminal is a lightweight terminal package for the Atom editor that embeds a native shell right inside the editor UI. It provides a familiar terminal experience—shell history, colors, and interactive programs—without switching windows, which streamlines workflows when building, flashing, or debugging embedded firmware from PlatformIO or other toolchains. The integration supports multiple terminal tabs, configurable shells, and user-defined startup commands so each project pane can pre-load environment variables or virtualenvs. Because embedded development often requires frequent command-line interactions (builds, serial monitors, log watchers), having the terminal adjacent to code and the project tree significantly reduces context switching. The package is intentionally minimal and focuses on stability and responsiveness rather than trying to replace full-featured terminal emulators. -

Repl.it
Online REPL for 15+ languages
This repository preserves an early open-source snapshot of the service that became Replit, a platform for writing and running code directly in the browser. The project’s core idea is instant, zero-setup programming: open a page, pick a language, type, and run—no local installs or environment wrangling. It combines an in-browser editor with a runnable backend or sandbox so code can execute safely and return output in seconds. Sharing and collaboration are first-class: code can be saved, forked, and embedded, which makes it useful for tutorials, classrooms, and quick demos. The architecture leans on simple web technologies so the learning curve stays low for educators and new programmers. Even as the commercial product evolved, this archive shows the foundational approach to making coding accessible anywhere with just a link. -

Trix
A rich text editor for everyday writing
A rich text editor for everyday writing. Compose beautifully formatted text in your web application. Trix is an editor for writing messages, comments, articles, and lists—the simple documents most web apps are made of. It features a sophisticated document model, support for embedded attachments, and outputs terse and consistent HTML. Trix is an open-source project from Basecamp, the creators of Ruby on Rails. Millions of people trust their text to Basecamp, and we built Trix to give them the best possible editing experience. Most WYSIWYG editors are wrappers around HTML’s contenteditable and execCommand APIs, designed by Microsoft to support live editing of web pages in Internet Explorer 5.5, and eventually reverse-engineered and copied by other browsers. Trix complete control over what happens after every keystroke, and avoids the need to use execCommand at all. -

jQuery.payment
Library for building credit card forms and validating inputs
Created by Stripe and archived on GitHub, jquery.payment is a small jQuery plugin that formats credit card inputs—numeric grouping, expiry dates, CVC—as you type and validates card numbers, expiry, and CVC with client-side checks. While deprecated in favor of Stripe Elements, it remains useful for legacy implementations. -

Atom Beautify
Universal code formatting plugin
atom‑beautify is a universal code formatting plugin for the Atom text editor, offering support for numerous languages and formatter engines to clean or prettify source code. Many users are experiencing issues when installing third-party beautifiers (e.g., Uncrustify, PHP-CS-Fixer, and many more). A possible solution is a "cloud" service that provides remote access to these beautifiers. Atom-Beautify would then communicate with these services, allowing for zero-installation beautification. Some of the supported beautifiers are developed for Node.js and are automatically installed when Atom-Beautify is installed. However, other beautifiers are command-line interface (CLI) applications and require you to manually install them. -

Chosen
jQuery plugin that makes select boxes more user-friendly
Chosen is a jQuery plugin that makes long, unwieldy select boxes much more user-friendly. Chosen automatically highlights selected options and removes disabled options. Chosen automatically sets the default field text ("Choose a country...") by reading the select element's data-placeholder value. If no data-placeholder value is present, it will default to "Select an Option" or "Select Some Options" depending on whether the select is single or multiple. You can change these elements in the plugin js file as you see fit. -

DocPad
Empower your website frontends with layouts and meta-data
DocPad is a dynamic static site generator built on Node.js that streamlines web development by allowing use of layouts, meta‑data, templating preprocessors (Markdown, Jade, CoffeeScript, etc.), partials, skeletons, file‑watching, querying, and a rich plugin system for building powerful static sites quickly. Completely file based, meaning there are no pesky databases that need to be installed, and for version control you get to use systems like Git and SVN, which you're already used to. Write your documents in any language, markup, templating engine, or pre-processor you wish (we're truly agnostic thanks to your plugin system). You can even mix and match them when needed by combining their extensions in a rails-like fashion. -
17
Git Time Machine
Atom package that allows you to travel back in commit history
git-time-machine is a user interface (often as an editor plugin or UI extension) that allows users to browse a file’s history visually, stepping back and forth through revisions in Git like a “time machine.” It shows changes to a file over time, lets users compare older states, and often provides diff and blame views to understand how the file evolved. Instead of just opening a commit log or diff, git-time-machine gives an interactive, incremental experience where you can slide through versions and see content changes in place. This is especially helpful when diagnosing when bugs were introduced, exploring regression contexts, or reviewing code evolution visually. For projects with many commits, it accelerates historical exploration, and it is commonly integrated into editors so developers can use it in their working environment. -

Odometer
Smoothly transitions numbers with ease. #hubspot-open-source
Odometer is a lightweight JavaScript and CSS library for animating numbers with a smooth rolling effect, similar to a car’s odometer. It provides a visually engaging way to display counters, statistics, or values that update dynamically in dashboards and web apps. The library requires minimal setup—just drop in the script and apply the class to an element, then update the number to trigger the animation. It supports multiple themes and styles, all implemented with CSS so they are easy to customize. The animation is GPU-accelerated and designed to be smooth even for rapid updates. Odometer is often used in marketing sites, financial dashboards, and gamified interfaces where numeric feedback benefits from a touch of motion and polish. -

SLOC
simple tool to count SLOC (source lines of code)
sloc is a simple, fast tool for counting lines of code that’s designed to be used from both the command line and Node.js scripts. It tallies physical lines, source lines, comment lines, and blank lines, giving you a quick snapshot of code size across files or entire directories. The utility is language-aware through lightweight detectors and patterns, so it can ignore comments correctly and avoid counting generated or minified files if you configure it to. Output can be human-readable for quick checks or machine-readable (like JSON) for CI pipelines that track repository growth over time. It supports typical developer conveniences such as glob patterns, file/directory ignores, and sensible defaults so you can drop it into existing workflows without fuss. Teams often wire sloc into build steps to watch trends, compare modules, or enforce thresholds before merging changes, making it a handy maintenance metric rather than a vanity number. -

Turbolinks Classic
Classic version of Turbolinks
Turbolinks Classic is a now-deprecated JavaScript library (largely used in Rails projects) for speeding up navigation by intercepting link clicks and replacing only the <body> and page title instead of reloading the entire page. It avoids recompiling JS and CSS on each navigation, improving perceived performance. Turbolinks makes following links in your web application faster. Instead of letting the browser recompile the JavaScript and CSS between each page change, it keeps the current page instance alive and replaces only the body (or parts of) and the title in the head. Think CGI vs persistent process. -

zxcvbn
Low-budget password strength estimation
For over 30 years, password requirements and feedback have largely remained a product of LUDS: counts of lower- and uppercase letters, digits and symbols. LUDS remains ubiquitous despite being a conclusively burdensome and ineffective security practice. zxcvbn is an alternative password strength estimator that is small, fast, and crucially no harder than LUDS to adopt. Using leaked passwords, we compare its estimations to the best of four modern guessing attacks and show it to be accurate and conservative at low magnitudes, suitable for mitigating online attacks. We find 1.5 MB of compressed storage is sufficient to accurately estimate the best-known guessing attacks up to 105 guesses, or 104 and 103 guesses, respectively, given 245 kB and 29 kB. zxcvbn can be adopted with 4 lines of code and downloaded in seconds. It runs in milliseconds and works as-is on web, iOS and Android. -

APM (Atom Package Manager)
Atom Package Manager
APM is the command-line package manager built specifically for the Atom editor; it functions as a thin, Atom-aware wrapper around npm that handles installing, publishing, and managing Atom packages. Unlike a typical npm install, APM installs packages into Atom’s package directory and applies Atom-specific defaults and lifecycle hooks so community packages behave consistently inside the editor. It also exposes commands to publish packages to the Atom ecosystem and to fetch package metadata, making it the standard developer tool for creating and distributing Atom extensions. The tool is designed to be simple and scriptable so package authors can automate builds, test installs, and CI workflows. Because it integrates closely with Atom’s expectations (package locations, service activation, etc.), using APM simplifies the developer experience compared with manually managing package folders. -

Activate Power Mode
Atom package - Activate POWER MODE to write your code in style
Activate Power Mode is an Atom plugin that adds playful visual and audio effects—particle trails, screen shaking, combo counters—when coding at speed. Inspired by Code in the Dark’s “power mode”, it enhances typing flow, with customizable thresholds and combo modes to moderate effect frequency. -

Aglio
An API Blueprint renderer with theme support that outputs static HTML
Aglio is a renderer for API Blueprint documents (Markdown‑based API description format), producing static HTML documentation with theme support. It functions as both a command‑line executable and a Node.js library, allowing integration into pipelines or live-preview workflows. An API Blueprint renderer that supports multiple themes and outputs static HTML that can be served by any web host. API Blueprint is a Markdown-based document format that lets you write API descriptions and documentation in a simple and straightforward way. Currently supported is API Blueprint format 1A. Fast parsing thanks to Protagonist. Support for custom colors, templates, and theme engines. Include other documents in your blueprint. -

Angular Google Maps
AngularJS directives for the Google Maps Javascript API
Angular Google Maps is a set of AngularJS directives written in CoffeeScript and JavaScript for integrating Google Maps into AngularJS applications. This will generate source maps for development (angular-google-maps_dev_mapped.js) (non minified) and source maps to minified (angular-google-maps_dev_mapped.min.js) files. They each have their own corresponding map files. To get the coinciding source files you will need to copy the generated /tmp directory (currently not under scc). If you plan to hack on the directives or want to run the example, first thing to do is to install NPM dependencies.
