Vulcan
A toolkit to quickly build apps with React, GraphQL & Meteor
Vulcan is a framework that gives you a set of tools for quickly building React & GraphQL-based web applications. It can handle data loading, e-mail notifications, automatic form generation, and much more, out of the box. Vulcan is unique in that it spans the full-stack, from the database to the browser. While there exist many excellent back-end frameworks or backend-as-a-service providers, these all still require you to handle the front-end code yourself, including building a set of components to read, write, and display data. However, being full-stack, Vulcan is able to speed up these repetitive tasks by providing a whole range of helper components that are fine-tuned to the Vulcan back-end, and as a result just work out of the box. In order to make working with Vulcan easier (especially when it comes to updating the core packages), you are also free to follow the more complicated “two-repo” pattern, with the two repositories. -

WWWBasic
wwwBASIC is an implementation of BASIC that runs on Node.js & the Web
wwwBASIC is a JavaScript-based implementation of the classic BASIC programming language designed to run seamlessly in web browsers and Node.js environments. Created by Google, it allows developers and enthusiasts to write and execute BASIC programs directly within HTML pages or via command-line tools. The interpreter compiles BASIC source code into JavaScript at load time, enabling efficient execution within modern web environments without requiring external emulators or plugins. It supports traditional BASIC constructs such as loops, conditionals, and I/O operations, along with 24-bit color graphics functions (PSET, LINE, CIRCLE) and input handling (INKEY$, GETMOUSE). wwwBASIC brings retro programming into the modern web era, making it ideal for educational purposes, historical software preservation, and interactive demonstrations -

WatchIt App
Open movies everywhere
WatchIt decentralizes the way you watch your movies. In short, it is a "collective entertainment methodology" in which each user consumes movies from the network and at the same time shares movies with other users. Indeed, Watchit is a movie playback system, in its most basic form it allows you to filter, search, play movies. Well, in order to decentralize our movies so that everyone can have access to them, we resorted to incredible tools such as IPFS and OrbitDB, which allowed us to have created a DAPP (Decentralized App). In simple words, Watchit is an application that does not require external resources, but rather everyone helps everyone to make it work. It is also possible that WatchIt can be synchronized through different movie channels opening the possibility to many libraries with different content across the network. -

Water.css
A drop-in collection of CSS styles to make simple websites
water.css is a “classless” CSS framework that instantly beautifies plain HTML without adding custom classes to your markup. By targeting native HTML elements—headings, paragraphs, forms, tables, and buttons—it applies sensible defaults for spacing, typography, and contrast, producing a clean, readable layout out of the box. The stylesheet is intentionally small and dependency-free, making it a convenient drop-in for prototypes, documentation, and minimalist sites where heavy frameworks are overkill. It includes automatic dark and light themes and exposes CSS variables so you can adjust colors or spacing while keeping the overall aesthetic. Because it respects semantic HTML, it plays well with accessibility tools and reduces the risk of brittle component overrides. The result is a fast path to “good enough” styling that remains easy to customize when a project grows. -

WorkerVless2sub
Automate batch replacement to generate subscription generators
WorkerVless2sub is a dedicated subscription generator focused on providing “preferred line” subscriptions by processing VMess, VLESS, Trojan nodes, filtering and replacing automatically via a Cloudflare Worker script. The idea is you supply node lists (or use existing APIs/CSV sources) and the worker filters them by criteria like speed or reliability and then emits a subscription link for end-users. It supports deployment on Cloudflare Pages or Workers, offers configuration via variables like HOST, UUID, PATH, ADD, ADDAPI etc., and has an Apache-2.0 license. The tool supports both IPv4 and IPv6 node sources, speed test CSV inputs, and logic to drop nodes that don’t meet the threshold (DLS variable). It has a sizeable star count and forks indicating broader adoption in self-hosted proxy subscription communities. The README also explicitly warns about hosting personal private nodes in the script if intending public use. -

ast-hook-forjs-re
AST-based JavaScript reverse engineering and variable tracing toolkit
ast-hook-for-js-RE is an open source JavaScript reverse engineering toolkit designed to help analysts locate and understand client-side encryption logic used by web applications. It works by intercepting browser traffic through a local proxy server and modifying JavaScript code before it executes in the browser. Using Abstract Syntax Tree (AST) transformations, it injects hook functions into the code to monitor variable assignments and other runtime changes during execution. This allows ast-hook-for-js-RE to capture variable values in memory and store them in a searchable database, effectively enabling variable-level monitoring of program execution. When a user encounters encrypted parameters in network requests, the captured variable data can be searched to determine where those values originated in the code. Once the relevant variable and code location are identified, analysts can trace backward to extract or reproduce the encryption logic used by the site. -

axe-core
Accessibility engine for automated Web UI testing
Axe is an accessibility testing engine for websites and other HTML-based user interfaces. It's fast, secure, lightweight, and was built to seamlessly integrate with any existing test environment so you can automate accessibility testing alongside your regular functional testing. Axe-core has different types of rules, for WCAG 2.0 and 2.1 on level A and AA, as well as a number of best practices that help you identify common accessibility practices like ensuring every page has an h1 heading, and to help you avoid "gotchas" in ARIA like where an ARIA attribute you used will get ignored. With axe-core, you can find on average 57% of WCAG issues automatically. Additionally, axe-core will return elements as "incomplete" where axe-core could not be certain, and manual review is needed. -

beautiful-html-templates
A library of HTML slide templates
beautiful-html-templates is a reusable library of HTML slide templates made for coding agents that need to produce polished presentation decks automatically. It gives agents a structured way to choose a visual direction, clone the right template, and adapt it to a user’s content brief. The project includes an index-driven workflow, with guidance files that explain how an agent should inspect available templates and match them to the requested style. Its templates are intended to be practical starting points rather than generic blank layouts. The library is useful for AI-assisted deck creation, branded one-off presentations, and fast visual prototyping. Its main value is helping agents create attractive HTML-based slides without designing every layout from scratch. -
