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. -

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. -

BuckyClient
Collect performance data from the client
BuckyClient is a HubSpot-provided JavaScript client that runs in the browser and collects performance data from clients, sending it to the Bucky server, which forwards metrics to endpoints like StatsD, Graphite, or OpenTSDB. It can automatically measure how long your pages take to load, how long AJAX requests take and how long various functions take to run. Most importantly, it's taking the measurements on actual page loads, so the data has the potential to be much more valuable than in vitro measurements. Modern browsers log a bunch of page performance data, Bucky includes a method for writing all of this in one go. It won't do anything on browsers that don't support the performance.timing API. Call it whenever; it will bind an event if the data isn't ready yet. -

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. -

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. -

GSS Engine
GSS engine
GSS is a JavaScript layout engine based on Grid Style Sheets (constraint CSS) using Cassowary constraint solver. It enables declarative relational layouts—expressing 'item A aligned to the right of item B'—and compiles these constraints into standard styles at runtime or build-time. Though experimental and labeled unstable, it showcases advanced layout paradigms beyond traditional CSS.
