Twemoji
Simple library that provides standard Unicode emoji for all platforms
Twitter’s open source emoji has you covered for all your project's emoji needs. With support for the latest Unicode emoji specification, featuring 3,245 emojis, and all for free. As an open source project, attribution is critical from a legal, practical and motivational perspective in our opinion. The graphics are licensed under the CC-BY 4.0 which has a pretty good guide on best practices for attribution. Although there are two kinds of parsing supported by this utility, we recommend you use DOM parsing, explained below. Each type of parsing accepts a callback to generate an image source or an options object with parsing info. The second kind of parsing is string parsing. This is unrecommended because this method does not sanitize the string or otherwise prevent malicious code from being executed; such sanitization is out of scope. -

big.js
Fast JavaScript library for arbitrary-precision decimal arithmetic
big.js is a compact JavaScript library for arbitrary-precision decimal arithmetic. It avoids many floating-point accuracy problems that occur with JavaScript’s native Number type. Values are stored using a decimal coefficient, exponent, and sign rather than ordinary binary floating-point representation. Its API supports arithmetic, comparisons, powers, square roots, rounding, and common numeric formatting methods. Precision and rounding behavior can be configured for operations such as division. The library has no runtime dependencies and is only about 6 KB when minified. It supports browsers, Node.js, ES modules, CommonJS, and other JavaScript environments while keeping the API deliberately smaller than bignumber.js or decimal.js. -

body-parser
Node.js body parsing middleware
Node.js body parsing middleware. Parse incoming request bodies in a middleware before your handlers, available under the req.body property. As req.body's shape is based on user-controlled input, all properties and values in this object are untrusted and should be validated before trusting. For example, req.body.foo.toString() may fail in multiple ways, for example the foo property may not be there or may not be a string, and toString may not be a function and instead a string or other user input. The bodyParser object exposes various factories to create middlewares. All middlewares will populate the req.body property with the parsed body when the Content-Type request header matches the type option, or an empty object ({}) if there was no body to parse, the Content-Type was not matched, or an error occurred. -

Brunch
Web applications made easy
Brunch lets you focus on what matters most, solving real problems instead of messing around with the glue. By being opinionated about your build pipeline, Brunch is able to provide a smooth and fast experience, and makes your config files take a drastic cut. It doesn't take much to get around with brunch. 'brunch new' to create a new project. 'brunch build' to build. 'brunch watch' to live-compile. Installation is one-line, once you have node.js. You will find that the typical config of a Brunch application is an order of magnitude simpler, compared to Webpack, Grunt, or Gulp. Besides configs, brunch is also simpler in terms of commands. Grunt / Gulp commands replicate all plugins it loads. Brunch always has three commands: new, build and watch. Build / watch commands may receive optional production flag which will tell Brunch to optimize assets, javascripts and stylesheets. -

Deoptigate
Investigates v8/Node.js function deoptimizations
Deoptigate is a Node.js performance-analysis tool for investigating V8 function optimizations and deoptimizations. It can run a Node.js application with the necessary V8 logging enabled or analyze existing V8 log files. Results are presented through an interactive browser interface rather than raw diagnostic output. The report summarizes optimizations, deoptimizations, and inline cache activity for each source file. Source code is annotated with severity-based markers that highlight potential performance problems. Selecting a marker reveals more detailed information about the corresponding V8 event. It is intended for developers diagnosing JavaScript performance issues caused by V8's speculative optimization behavior. -

Hyper Snazzy
Elegant Hyper theme with bright colors
Hyper Snazzy is a bright color theme designed for the Hyper terminal application. It applies the Snazzy palette to Hyper through a small installable theme package. Installation can be performed directly through Hyper's built-in package command. The theme focuses entirely on terminal presentation rather than adding commands, shell behavior, or productivity features. For the appearance shown in the project's screenshot, the author recommends using the Pure prompt, Menlo font, and zsh-syntax-highlighting. The repository also links to Snazzy adaptations for iTerm2, Windows Terminal, VS Code, Vim, Neovim, Kitty, Alacritty, and many other environments. This makes Hyper Snazzy one implementation of a broader cross-application visual theme family. -

Opentip
Opentip is an open source javascript tooltip
Opentip is an open-source JavaScript library for adding configurable tooltips to web interfaces. Tooltips can include small pointer stems and use multiple predefined or custom visual styles. Content can be supplied directly or loaded asynchronously through AJAX. The library automatically repositions tooltips when their original placement would move outside the browser viewport. Developers can activate tips through hover, clicks, form submission, or custom application events. CSS3 animations provide animated appearance and dismissal behavior. Opentip uses an adapter architecture that can work with native JavaScript as well as frameworks such as jQuery and Prototype. -

Pokedex.org
Offline-capable Pokédex web site
Pokedex is an offline-capable Pokémon encyclopedia built as a fully client-side JavaScript web application. It uses Service Workers to cache application resources so the Pokédex remains usable without a network connection. PouchDB provides browser-side data storage, while Web Workers move heavier processing away from the main interface thread. The UI is rendered with virtual-dom to keep interactions responsive on desktop and mobile devices. Pokémon data can be generated from PokéAPI and packaged into local database resources used by the application. The repository includes development, build, testing, and Service Worker versioning workflows. The project is now unmaintained but remains a notable example of an offline-first progressive web application architecture. -

Q
A promise library for JavaScript
Q is a JavaScript promise library created before native promises became standard across modern browsers and Node.js. It lets asynchronous functions return promise objects representing future values or errors instead of relying entirely on nested callbacks. Promise chains flatten asynchronous control flow and automatically propagate failures toward shared error handlers. The library provides deferred objects, combinators, delays, timeouts, callback adapters, and utilities for composing asynchronous operations. It can interoperate with promise implementations from libraries such as jQuery, Dojo, When.js, and WinJS. Q was distributed for browsers, CommonJS, AMD, Bower, and other historical JavaScript environments. The repository is now archived, and its maintainers recommend native JavaScript promises for new development. -

Style2Paints
Sketch + style = paints
style2paints is an AI-assisted colorization system aimed primarily at line art and manga, turning monochrome drawings into colored illustrations with minimal manual effort. It combines automatic color inference with user guidance, letting artists nudge the model using sparse color hints, masks, or style references. The pipeline focuses on preserving line quality while spreading coherent colors and shading across regions that are often ambiguous to purely automatic methods. Iterative refinement is a core workflow: you can add or adjust hints, rerun inference, and progressively converge on a desired palette and lighting. Beyond flat fills, the model attempts plausible shading and highlights so the result feels less like a “paint bucket” and more like a finished illustration. Because it’s built for artists rather than only researchers, the project emphasizes an approachable UI, predictable edits, and reproducible outputs across sessions. -

Zip.js
JavaScript library to zip and unzip files
Zip.js is a JavaScript library for creating, reading, and editing ZIP files directly in the browser or in Node.js environments, supporting various compression methods and encryption. -
19
Zoomerang.js
Drop in zoom anything
Zoomerang.js is a lightweight JavaScript library for adding smooth click-to-zoom behavior to almost any element on a web page. Developers attach it to elements with a simple selector-based API and the library handles the visual transition automatically. Images, text, buttons, and other HTML elements can be enlarged while preserving their appearance. Clicking outside the enlarged content or invoking the API restores the original layout. Configuration options control animation duration, background color, padding, and maximum dimensions. Events and programmatic methods allow applications to coordinate custom behavior with zoom transitions. The library has no framework dependency and was distributed through npm, Bower, Component, or a direct script include. -

css-doodle
A web component for drawing patterns with CSS
<css-doodle /> is based on Shadow DOM v1 and Custom Elements v1. You can use it on all major browsers right now without polyfills. The component will generate a grid of divs by the rules (plain CSS) inside it. You can easily manipulate those cells using CSS to come up with a graphic pattern or an animated graph. The limit is the limit of CSS itself. Download the latest version or include it directly from a CDN. You can also install it from npm and import the module in JavaScript. The syntax of CSS-doodle is based on CSS and provides several extra utility functions and shorthand properties. The number of rows and columns in the grid is defined by the grid attribute on the element, ranging from 1 to 64. Its default is 1x1 when no value or 0 is given. The row or column is limited up to 4096 only when the grid is 1-dimensional. -

edgetunnel
edgetunnel 2.0 VLESS/Trojan
edgetunnel is a modified version of a serverless tunnelling solution designed to run on platforms like Cloudflare Workers and Pages, enabling protocols such as VLESS and Trojan to be exposed through edge-functions rather than traditional servers. The project’s fork by cmliu emphasizes conversion of protocol configuration (especially VLESS) into subscription links, so that users can deploy and then generate “Clash” or “Sing-box” compatible subscription content easily. It provides a streamlined way to host proxy endpoints without managing a full server stack, instead leveraging the edge network of Cloudflare for distribution and potential performance. Because it runs at the edge, latency can be minimized and deployment complexity simplified; users supply configuration variables (host, port, UUID, path) and the script handles mapping to technical protocols and subscription formatting. -

fuite
A tool for finding memory leaks in web apps
Fuite is a command-line tool for detecting JavaScript memory leaks in web applications through automated Chrome testing. It launches Chromium with Puppeteer and repeatedly runs user interactions to identify objects that accumulate across iterations. The analyzer checks heap objects, event listeners, DOM nodes, arrays, maps, sets, and plain objects. Its default scenario navigates internal links and returns to the starting page, which works well for client-rendered applications. Custom scenarios can model dialogs, authentication, navigation, or other application-specific interactions. Results can be written to JSON, and optional heap snapshots support deeper analysis in Chrome DevTools. Fuite also exposes a JavaScript API for integrating leak detection into other tooling. -

FreeMarker template engine
Generates text that depends on changing data (like dynamic HTML).
FreeMarker is a template engine. That is, it provides an easy way to generate text (HTML, source code, configuration files, emails, etc.) that depends on changing data. It's designed to separate the rendering/formatting logic (like visual design, HTML issues, etc.) from the backing application logic and technical complexity. It has a flexible API so you can integrate it into your application the way that best fits it. -

Calibre-Web Automated
Calibre-Web but Automated and with tons of New Features
Calibre-Web-Automated (CWA) is an all-in-one, self-hosted solution for managing an ebook library that combines the modern, lightweight web UI style of Calibre-Web with the deeper tooling and conversion capabilities associated with Calibre. The goal is to reduce the common “two-service” setup where users run Calibre-Web for browsing and Calibre separately for conversions, metadata fixes, and automation, by packaging those workflows together in a single system. CWA keeps the familiar strengths of Calibre-Web, like a responsive interface, OPDS feeds for e-readers, and strong user/permission management, while layering in extensive automation features that handle ingest, conversion, metadata enforcement, and library organization with less manual effort. It also expands authentication options (including modern OAuth/OIDC flows) and adds quality-of-life improvements such as enhanced search/filtering, multi-language UI support, and better device-centric workflows for sending to e-readers.
