90s Cursor Effects
Old-school cursor effects for your browser built with modern JS
"Knowing the codes" used to be all the rage, I want to bring a few back. A repo of the old effects that inspired creativity and the desire to learn at least a little code around the world. Modernized so they're a little more efficient, and just as annoying (and twice as fun) as they were before. -

98.js
Web-based Windows 98 desktop recreation
98 is a web-based recreation of the Windows 98 operating system that runs entirely in the browser, replicating the look, feel, and behavior of the classic desktop environment. Built using JavaScript, HTML, and CSS, it recreates core components such as the desktop, taskbar, file explorer, and system applications with remarkable attention to detail. The project includes functional versions of programs like Notepad, Calculator, Minesweeper, and even a simulated Internet Explorer, providing an interactive nostalgic experience. It uses a virtual filesystem to store user data and supports drag-and-drop functionality, enabling users to interact with files similarly to a real operating system. The interface is highly polished, with support for themes, animations, and even hidden easter eggs that mimic the quirks of the original Windows 98 experience. While not a true emulator, it effectively simulates the user interface and behavior of the OS in a browser environment. -

Alfy
Create Alfred workflows with ease
Alfy offers the possibility of caching data, either with the fetch or directly through the cache object. An important thing to note is that the cached data gets invalidated automatically when you update your workflow. This offers the flexibility for developers to change the structure of the cached data between workflows without having to worry about invalid older data. You can remove these properties from your info.plist file as they are being added automatically at install time. When developing your workflow it can be useful to be able to debug it when something is not working. This is when the workflow debugger comes in handy. You can find it in your workflow view in Alfred. Press the insect icon to open it. Alfred lets users set environment variables for a workflow which can then be used by that workflow. This can be useful if you, for example, need the user to specify an API token for a service. You can access the workflow environment variables from process.env. -

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. -

Atropos
Stunning touch-friendly 3D parallax hover effects
Atropos is a lightweight, open-source JavaScript library designed to add visually striking 3D parallax and hover effects to webpage elements — giving a sense of depth and interactivity when users hover or touch elements (cards, images, UI components). It works not only with vanilla JavaScript, but also provides integrations or support for modern frameworks (React, Vue, Web Components, etc.), making it easy to incorporate into a variety of web projects. Because Atropos is very small (just ~2 KB minified + gzipped) and has zero dependencies, it's ideal for performance-conscious applications and does not bloat bundle size. Developers can customize parameters — for example, perspective, rotation, scale, and responsiveness to pointer/touch events — to fine-tune how elements respond to user interaction. -

AutoCannon
fast HTTP/1.1 benchmarking tool written in Node.js
An HTTP/1.1 benchmarking tool written in node, greatly inspired by wrk and wrk2, with support for HTTP pipelining and HTTPS. If the PORT environment variable is set, the URL can be a path. Use a warm up interval before starting sampling. This enables startup processes to finish and traffic to normalize before sampling begins. There are two tables, one for the request latency, and one for the request volume. The latency table lists the request times at the 2.5% percentile, the fast outliers; at 50%, the median; at 97.5%, the slow outliers; at 99%, the very slowest outliers. Here, lower means faster. When in workers mode, you need to pass in an absolute file path to all the options that accept a function. This is because a function passed into the main process can not be cloned and passed to the worker. So instead, it needs a file that it can require. When combining a fixed amount of requests with concurrent connections and an overallRate limit, autocannon will distribute the requests. -

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. -

Bilibili Helper
Auxiliary tool that can replace the player, push notifications, etc.
Bilibili (bilibili.com) Auxiliary tool that can replace the player, push notifications and perform some shortcut operations. Bilibili (bilibili.com) is an auxiliary tool that can download videos, query the sender of the barrage, and some very useful live broadcast area functions. An auxiliary extension for Bilibili (bilibili.com) which allows users to bypass playback restrictions, replace video players and use shortcuts. Starting from a certain version, Bilibili Assistant uses special technical methods to realize the unlocking function of regional restrictions. It was known to only be able to re-fix the feature via a proxy method, but the cost was prohibitive and we decided not to maintain the feature anymore. Please use an extension that specializes in this type of service, such as unblock youku. -

Bloom
An open source, agentic Loom alternative
Bloom is an open-source, agent-centric video recording and processing platform designed as a modern alternative to tools like Loom, but with a strong emphasis on AI-driven workflows and programmability. It allows users to record sessions locally while simultaneously preparing those recordings to be processed, indexed, and analyzed by AI systems, effectively turning simple screen captures into structured, queryable data. The project is part of the broader VideoDB ecosystem, which focuses on giving AI agents perception and memory through video, enabling them to understand and act upon visual information. Bloom supports the concept of “agentic video,” where recordings are not just passive media files but interactive assets that can be searched, summarized, and transformed into workflows or insights. This makes it particularly useful for use cases such as debugging AI agents, documenting processes, training models, or creating automated video-based reports. -

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. -

Cerebral
Declarative state and side effects management for popular JavaScript
Declarative state and side effects management for popular JavaScript frameworks. The entire Cerebral codebase has been rewritten to encourage contributions. The code is cleaned up, commented and all code is in a "monorepo". That means you can run tests across projects and general management of the code is simplified a lot. When you make a code change you should create a branch first. When the code is changed and backed up by a test you can commit it from the root. A declarative approach to application logic also allows us to build developer tools that builds the mental image of this complexity for you. It makes perfect sense for us to write our UIs with declarative code. The reason is that we need to reuse UI elements and compose them together in different configurations. UIs are complex. But what about our application logic? Applications are becoming more complex in nature as we push the boundaries of user experiences. -
