Argus Eyes
A lightweight commandline tool for visual regression testing of UI
A lightweight command line tool for visual regression testing of UI components. After installing, you want to tell argus eyes which pages and which components to check for visual regression. Argus eyes work by going over a straightforward JSON file containing the resolutions you want to capture, as well as the pages with theirs url's, and the components with their CSS-selectors. Once argus eyes know where to find the components, it's time for some command line action. The first command you want to use is $ argus-eyes capture master. This makes argus eyes go over the config file and take screenshots of all specified components in there. The screenshots are saved in .argus-eyes/master and this set of screenshots can be compared with another set. -

Atom LaTeX
Compile LaTeX or knitr documents from within Atom
Compile LaTeX, knitr, literate Agda, literate Haskell, or Pweave documents from within Atom. Use the Atom package manager and search for "latex", or run apm install latex from the command line. A reasonably up-to-date and working TeX distribution is required. The only officially supported distributions are TeX Live and MiKTeX. Although, the latter is not as well tested and supported as TeX Live, hence using TeX Live is highly recommended. You need to ensure that the package can find your TeX distribution's binaries; by default, the package uses your PATH environment variable, as well as the following search paths on Linux and macOS. -

Atom Linux
The hackable text editor
Atom is a hackable text editor for the 21st century, built on Electron, and based on everything we love about our favorite editors. We designed it to be deeply customizable, but still approachable using the default configuration. A set of encrypted code signing certificates were exfiltrated; however, the certificates were password-protected and we have no evidence of malicious use. As a preventative measure, we will revoke the exposed certificates used for the Atom application. Revoking these certificates will invalidate some versions of Atom. When we introduced Atom in 2011, we set out to give developers a text editor that was deeply customizable but also easy to use—one that made it possible for more people to build software. While that goal of growing the software creator community remains, we’ve decided to retire Atom in order to further our commitment to bringing fast and reliable software development to the cloud via Microsoft Visual Studio Code and GitHub Codespaces. -

Basscss
Low-level CSS Toolkit, the original Functional/Utility/Atomic CSS
Using clear, humanized naming conventions, Basscss is quick to internalize and easy to reason about while speeding up development time with more scalable, more readable code. Things behave exactly as expected with immutable utilities and styles that do one thing well to help prevent common pitfalls with CSS. Reusable, interoperable styles work like building blocks to lay the foundation for any stylesheet and can be mixed and matched in any number of combinations. Basscss strikes a balance between consistency and flexibility to allow for rapid prototyping and quick iterative changes when designing in the browser. Basscss provides lightweight, performant styles and flexible utilities to design for any device and to help reduce boilerplate in stylesheets. Modular and customizable typography and layout styles don’t dictate what things should look like and play well with other stylesheets and frameworks. -

Beaker Browser
An experimental peer-to-peer Web browser
Beaker is an experimental, open source peer-to-peer Web browser that allows you to create websites from inside the browser. It has a built in editor that lets you edit your source code side-by-side with your page. With Beaker you can create a new P2P site with just a click, and allow other Beaker users to visit your site directly from your computer! Beaker works through a new peer-to-peer network called Hypercore Protocol, which allows other Beaker users to access these websites with no servers necessary. This is great for settings like offices and classrooms where you'd need an easy way to share a website without having to set up servers or even touch the command line. -

Bootbox
Wrappers for JavaScript alert(), confirm() and other flexible dialogs
Bootbox.js is a small JavaScript library which allows you to create programmatic dialog boxes using Bootstrap modals, without having to worry about creating, managing, or removing any of the required DOM elements or JavaScript event handlers. Bootbox provides three functions, alert, confirm, and prompt, whose aim is to mimic their native JavaScript equivalents. Each Bootbox function calls a fourth public function, dialog, which you can use to create your own custom dialogs. See the Documentation for usage and to learn which options are available for each function. Tests are run using Karma using the Mocha test adapter. To run the tests yourself, simply run npm install within the project followed by npm test. Please note that this will require PhantomJS being installed and in your path - if it is not, you may run the tests and capture browsers manually by running karma start from the root of the project. -

Bowser
Bowser is a browser detector
A small, fast and rich-API browser/platform/engine detector for both browser and node. The library is made to help to detect what browser your user has and gives you a convenient API to filter the users somehow depending on their browsers. Version 2.0 has drastically changed the API. All available methods are on the docs page. Often we need to pick users' browser properties such as the name, the version, the rendering engine and so on. You could want to filter some particular browsers to provide any special support for them or make any workarounds. Settings for any particular OS or platform has more priority and redefines settings of standalone browsers. Thus, you can define OS or platform-specific rules and they will have more priority in the end. More of API and possibilities you will find in the docs folder. -

CCapture.js
A library to capture canvas-based animations at a fixed framerate
CCapture.js is a JavaScript library designed to capture high-quality recordings of HTML5 canvas animations at a fixed and consistent frame rate. Unlike traditional screen recording tools, it decouples rendering speed from capture speed, allowing developers to generate smooth video outputs even when frames take longer to compute. It works by overriding time-related browser functions such as requestAnimationFrame and Date.now to simulate a stable time progression, ensuring every frame is captured accurately. This approach enables the creation of high-resolution videos, slow-motion sequences, or complex visualizations without dropped frames. The library supports multiple export formats including WebM, GIF, PNG sequences, and JPEG archives, making it flexible for different workflows. It integrates easily into browser-based creative coding environments like Three.js and p5.js, making it especially valuable for artists and developers producing generative visuals. -

CanvasBlocker
A Firefox extension to protect from being fingerprinted
This add-on allows users to prevent websites from using some Javascript APIs to fingerprint them. Users can choose to block the APIs entirely on some or all websites (which may break some websites) or just block or fake its fingerprinting-friendly readout API. Canvas Blocker's default setting, and my favorite! All websites not on the white list or black list can use the protected APIs. But values obtained by the APIs are altered so that consistent fingerprinting is not possible. If a website is not listed on the white list or black list, the user will be asked if the website should be allowed to use the protected APIs each time they are called. Block the protected APIs only for websites on the black list. Ignore all lists and allow the protected APIs on all websites. -

Claude HUD
A Claude Code plugin that shows what's happening
Claude HUD is a real-time monitoring add-on for Claude Code that places a persistent heads-up display directly in your interactive session, giving developers clear insight into what the AI engine is doing at every moment. Instead of guessing about hidden processes behind the scenes, users see the amount of context remaining in the current session, tools being used, active running agents, and the progress of TODO tasks that the AI has planned or is executing. This plugin was designed to reduce cognitive load and make agentic workflows more transparent, helping developers diagnose stalled tasks, understand resource usage, and manage multi-step reasoning sequences more effectively. It installs with zero configuration and appears immediately in Claude Code, making it helpful for both newcomers and seasoned users who want better situational awareness without interrupting their workflow. -

Clean Code JavaScript
Clean Code concepts adapted for JavaScript
clean-code-javascript adapts Robert C. Martin’s Clean Code principles to the JavaScript ecosystem, presenting them as pragmatic, example-driven guidelines rather than a prescriptive style guide. It focuses on writing code that is readable, searchable, testable, and easy to refactor, using before/after (“Bad/Good”) snippets to make each idea concrete. The repository covers everyday concerns—naming, functions, conditionals, objects, classes, and error handling—showing how small choices compound into maintainable systems. Modern JavaScript features (e.g., default parameters, destructuring, classes, array methods) are used to illustrate clearer APIs and fewer side effects. Throughout, the guidance encourages single-purpose functions, avoiding unnecessary context and duplications, and favoring functional patterns where they improve clarity. It’s a reference you dip into to assess your code’s clarity and consistency, not a checklist of rules to follow blindly. -

Clinic.js
Clinic.js diagnoses your Node.js performance issues
Node Clinic is a suite of diagnostic tools for Node.js applications, designed to help developers identify and resolve performance issues, memory leaks, and other common problems in their code. -
23
CodeCopy
A browser extension that adds copy to clipboard buttons
CodeCopy is a browser extension that automatically adds “copy to clipboard” buttons to code blocks on popular documentation and Q&A sites. Its goal is to save developers time and frustration by making it a single click to copy example snippets, rather than manually selecting text and dealing with formatting issues. The extension detects code snippets on pages like GitHub, MDN, Gist, Stack Overflow, StackExchange, npm, Medium, and others, then overlays a small copy icon or button in the corner of each block. When a user clicks the button, codecopy uses the Clipboard API (or fallbacks) to copy the snippet to the clipboard with minimal visual noise or disruption. The repository provides the extension source, manifest, and build pipeline so that developers can contribute new site matchers or customize behavior. It is distributed under an MIT license and is available for multiple browsers, including Chrome, Firefox, and Opera. -

Codebox npm
Serverless private npm registry
Codebox npm is a serverless npm registry to allow companies that wish to keep their intellectual property. It allows the sharing of npm modules within a company but additionally allows access to all of the modules on public npm. One other major difference is that it replaces npm login authentication to be via GitHub / GitHub enterprise. Users are always required to be authenticated when using codebox as their npm registry. -

Color Thief
Grab the color palette from an image using just Javascript
The Color Thief package includes multiple distribution files to support different environments and build processes. Gets the dominant color from the image. Color is returned as an array of three integers representing red, green, and blue values. When called in the browser, the image argument expects an HTML image element, not a URL. When run in Node, this argument expects a path to the image. quality is an optional argument that must be an Integer of value 1 or greater, and defaults to 10. The number determines how many pixels are skipped before the next one is sampled. We rarely need to sample every single pixel in the image to get good results. The bigger the number, the faster a value will be returned. Gets a palette from the image by clustering similar colors. The palette is returned as an array containing colors, each color itself an array of three integers.
