    Argus Eyes

    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 Linux

    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.

    BSL

    BSL

    Body scroll locking that just works with everything

    Enables body scroll locking (for iOS Mobile and Tablet, Android, desktop Safari/Chrome/Firefox) without breaking scrolling of a target element (eg. modal/lightbox/flyouts/nav-menus). If the overflow property of the body is set to hidden, the body widens by the width of the scrollbar. This produces an unpleasant flickering effect, especially on websites with centered content. If the reserveScrollBarGap option is set, this gap is filled by a padding-right on the body element. If disableBodyScroll is called for the last target element, or clearAllBodyScrollLocks is called, the padding-right is automatically reset to the previous value. Works with vanilla JS and frameworks such as React / Angular / VueJS. Disables body scroll WITHOUT disabling scroll of a target element. Supports nested target elements (eg. a modal that appears on top of a flyout).

    Beginner JavaScript

    Beginner JavaScript

    Slam Dunk JavaScript

    Beginner JavaScript is the companion repository to a hands-on course that teaches modern JavaScript from the ground up using practical exercises and real code. It focuses on fundamentals—variables, types, functions, arrays, objects, DOM manipulation, and events—while introducing ES6+ features in approachable steps. The materials encourage learning by doing, with interactive challenges, starter files, and solutions you can compare against your own attempts. Clear explanations and incremental projects help learners build confidence before tackling more complex topics. Because everything runs in the browser with minimal tooling, setup is simple and newcomers can focus on the language rather than the build system. The repo doubles as a reference you can revisit later when you need to refresh syntax or patterns.

    Better Harness

    Better Harness

    Help your coding agents get better at getting better

    Better Harness is an open-source evaluation system for improving the workflows used by AI coding agents. Instead of reviewing only the final code change, it examines how an agent understood the task, executed work, validated results, delivered safely, and captured reusable lessons. It gathers project and session evidence while marking missing or unobserved behavior explicitly. Reports organize findings across five Agent Work Loop dimensions and connect each conclusion to visible supporting evidence. Supported gaps become prioritized recommendations with expected outcomes, repair boundaries, and acceptance checks. Repeated reports can be compared through a history view to observe workflow trends without claiming unsupported causation. Better Harness supports Claude Code, Codex, Qoder, and Cursor through host-specific plugins, commands, and report formats.

    Bower

    Bower

    A package manager for the web

    Bower offers generic, unopinionated front-end package management. It manages all the packages you need for a website, making sure they are all up-to-date and in the specific versions that you need. Bower can manage components that contain HTML, CSS, JavaScript, fonts or even image files. There’s no concatenating, minifying code or anything else - it just installs the right versions of the packages you need and their dependencies. How you use your packages will then be entirely up to you. Bower runs over Git and is package-agnostic, which means that a packaged component can be made up of any type of asset, and use any type of transport.

    CF-Workers-SUB

    CF-Workers-SUB

    Aggregates any of your nodes with multiple subscriptions

    CF-Workers-SUB is a project that uses Cloudflare Workers to aggregate or convert multiple subscription sources (for proxy nodes/configs) into a personalized subscription link for the user. Essentially, it lets you input your own node(s) and then generate a unified subscription endpoint that others can use with tools like Clash, Sing-box, or V2Ray. The repository emphasizes being user-friendly for scenarios where one has many proxy/node links but wants to streamline into a single subscription feed. It also supports variable configuration (token, built-in nodes, custom add/CSV/API sources) to produce automated “preferred line” generation. The project is aimed at “subscription” style services (i.e., providing proxies as subscriptions) rather than pure application logic, and is tailored toward self-hosters. It’s designed for ease of deployment on Workers or Pages, enabling people to maintain their own subscription link infrastructure cheaply.

    CSS Grid Generator

    CSS Grid Generator

    Generate basic CSS Grid code to make dynamic layouts

    CSS Grid Generator is a visual tool built to help web designers and developers quickly create CSS Grid layout code without writing the grid definitions manually. You select the number of columns, rows, and units (e.g., fr, px, %), then visually drag and place items, resize them and position them within the grid to prototype layouts by hand. Once the layout is arranged, the tool generates the corresponding HTML and CSS you can copy into your project—thus bridging the gap between design and code. The interface supports drag-and-drop of “divs” into grid cells, and you can experiment with grid gaps, spans and layout refinements in real time. Because it removes the barrier of hand-writing complex grid-template or grid-area definitions, it’s particularly useful for designers who are less comfortable with CSS or want rapid prototyping of grid layouts.

    CSSLint

    CSSLint

    Automated linting of cascading stylesheets

    CSSLint is an open-source CSS code quality tool originally written by Nicholas C. Zakas and Nicole Sullivan. A lint tool performs static analysis of source code and flags patterns that might be errors or otherwise cause problems for the developer. CSSLint is a tool to help point out problems with your CSS code. It does basic syntax checking as well as applying a set of rules to the code that look for problematic patterns or signs of inefficiency. The rules are all pluggable, so you can easily write your own or omit ones you don't want. You can integrate CSSLint into your favorite IDE to make checking your CSS code quality easy. In fact, some IDEs already have CSSLint built-in. Once you're familiar with the CSSLint command-line interface, the next step is to integrate it into your build system.
