glsl-sandbox
Shader editor and gallery
GLSL Sandbox is an in-browser playground for writing and sharing fragment shaders with instant visual feedback. It provides a minimal editor and a fullscreen WebGL viewport so your shader takes center stage, making it perfect for learning, live-coding, and showcasing visual experiments. The environment injects a small set of uniforms—time, resolution, mouse—so you can animate and interact without boilerplate. A public gallery lets creators browse, fork, and remix shaders, turning the site into a collaborative learning hub. Because everything runs client-side, iteration is fast and portable—just load the page and start typing. It has become a staple tool in the creative-coding community, lowering the barrier to entry for shader art and GPU programming. -

h5ai
HTTP web server index for Apache httpd, lighttpd and nginx
h5ai is a modern file indexer for HTTP web servers with a focus on your files. Directories are displayed in an appealing way and browsing them is enhanced by different views, a breadcrumb and a tree overview. Initially, h5ai was an acronym for HTML5 Apache Index but now it supports other web servers too. Requires PHP 7.0+ and works fine with Apache httpd, lighttpd and nginx. Best user experience with the latest versions of Chromium-based browsers, Firefox, Safari and Edge, but a static fallback is provided for older browsers or if JavaScript is disabled. -

single-file-cli
CLI tool to save complete web pages as single self-contained HTML file
SingleFile CLI is an open source command-line tool designed to save complete web pages as a single self-contained HTML file. It captures the rendered page in a headless browser and embeds all required resources directly into the output document, including stylesheets, scripts, images, and fonts. By consolidating every dependency into one file, it allows users to preserve a faithful copy of a web page that can be viewed offline without requiring external assets. SingleFile CLI works by controlling a browser through the Chrome DevTools Protocol, rendering the page before extracting and packaging all necessary resources. This approach helps ensure that the saved page closely matches the original appearance and functionality. SingleFile CLI can be used for automated archiving, research, documentation, or offline reading workflows where preserving a page exactly as displayed is important. -

uPlot
Chart for time series, lines, areas, ohlc and bars
μPlot is a fast, memory-efficient Canvas 2D-based chart for plotting time series, lines, areas, ohlc & bars; from a cold start it can create an interactive chart containing 150,000 data points in 135ms, scaling linearly at ~25,000 pts/ms. In addition to fast initial render, the zooming and cursor performance is by far the best of any similar charting lib; at ~40 KB, it's likely the smallest and fastest time series plotter that doesn't make use of context-limited WebGL shaders or WASM, both of which have much higher startup cost and code size. However, if you need 60fps performance with massive streaming datasets, uPlot can only get you so far. WebGL should still be the tool of choice for applications like realtime signal or waveform visualizations: See danchitnis/webgl-plot, huww98/TimeChart, epezent/implot, or commercial products like LightningChart®. -

user.js
Firefox privacy, security and anti-tracking: a comprehensive user.js
A user.js is a configuration file that can control Firefox settings - for a more technical breakdown and explanation, you can read more in the wiki. The arkenfox user.js is a template that aims to provide as much privacy and enhanced security as possible and to reduce tracking and fingerprinting as much as possible - while minimizing any loss of functionality and breakage (but it will happen). Everyone, experts included, should at least read the wiki, as it contains important information regarding a few user.js settings. Note that we do not recommend connecting over Tor on Firefox. Use the Tor Browser if your threat model calls for it, or for accessing hidden services. Also be aware that the arkenfox user.js is made specifically for desktop Firefox. Using it as-is in other Gecko-based browsers can be counterproductive, especially in the Tor Browser. -

vis-network
Display dynamic, automatically organised, customizable network views
Network is a visualization to display networks and networks consisting of nodes and edges. The visualization is easy to use and supports custom shapes, styles, colors, sizes, images, and more. The network visualization works smooth on any modern browser for up to a few thousand nodes and edges. To handle a larger amount of nodes, Network has clustering support. Network uses HTML canvas for rendering. As of 4.0, the network consists of individual modules which handle specific parts of the network. These modules have their own docs, options, methods and events which you can access by clicking on the modules. -

7.css
A JS-independent, tree-shakeable CSS framework
7.css is a CSS framework for building interface components that look like Windows 7. It is built on top of the GUI backbone of XP.css, which is an extension of 98.css. This framework relies on the usage of semantic HTML. To make a button, you'll need to use a button. Input elements require labels. Tabs rely on the role="tab" attribute. This page will guide you through that process, but accessibility is a primary goal of this project. It does not ship with any JavaScript, so it is compatible with your frontend framework of choice. -

Antigravity Claude Proxy
Proxy that exposes Antigravity provided claude / gemini models
Antigravity Claude Proxy is a purpose-built proxy server that enables developers to interface with Claude models through a standardized RESTful API, allowing tools and workflows that expect generic HTTP APIs to operate on Anthropic’s Claude without native support. The project acts as a translation layer, receiving web requests in common formats (such as OpenAI-style endpoints) and forwarding them to Anthropic’s API in the required structure, while converting responses back into a familiar shape. This makes it easier to integrate Claude into existing toolchains, scripts, notebooks, or agent frameworks that do not have built-in support for Anthropic’s native SDKs. It abstracts away key differences like authentication choreography, request schema quirks, and streaming protocols so client code can remain unchanged when switching between models. -

Cabin
Cabin is the best JavaScript and Node.js logging service and logging
Cabin is the best JavaScript and Node.js logging service and logging npm package. Cabin is a drop-in replacement and the best alternative to Sentry, Timber, Airbrake, Papertrail, Loggly, Bugsnag, etc. Cabin will automatically detect and mask the following list of extremely sensitive types of data in your logs. Reduce your disk storage costs through Cabin's automatic conversion of Streams, Buffers, and ArrayBuffers to simplified, descriptive-only objects that otherwise would be unreadable (and obviously pollute your log files and disk storage). Cabin works with the most popular Node.js HTTP frameworks (e.g. Express and Koa), request body handling packages (e.g. multer and body-parser), and the passport authentication framework. It supports Node v6.4+ and IE 10+ out of the box, and its browser-ready bundle is only 39 KB (minified and gzipped). -

Cheerio
Implementation of core jQuery designed for the server
Fast, flexible & lean implementation of core jQuery designed specifically for the server. Cheerio implements a subset of core jQuery. Cheerio removes all the DOM inconsistencies and browser cruft from the jQuery library, revealing its truly gorgeous API. Cheerio works with a very simple, consistent DOM model. As a result parsing, manipulating, and rendering are incredibly efficient. Cheerio wraps around parse5 parser and can optionally use @FB55's forgiving htmlparser2. Cheerio can parse nearly any HTML or XML document. Cheerio parses markup and provides an API for traversing/manipulating the resulting data structure. It does not interpret the result as a web browser does. Specifically, it does not produce a visual rendering, apply CSS, load external resources, or execute JavaScript. If your use case requires any of this functionality, you should consider projects like Puppeteer or JSDom. -
