    Buster

    Captcha solver extension for humans

    Save time by asking Buster to solve captchas for you. Buster is a Firefox extension which helps you to solve difficult captchas by completing reCAPTCHA audio challenges using speech recognition. Challenges are solved by clicking on the extension button at the bottom of the reCAPTCHA widget. It is not guaranteed that challenges are always solved, the limitations of the technology need to be considered. The continued development of Buster is made possible thanks to the support of awesome backers. If you'd like to join them, please consider contributing with Patreon, PayPal or Bitcoin. The success rate of the extension can be improved by simulating user interactions with the help of a client app. Follow the instructions from the extension's options to download and install the client app on Windows, Linux and macOS, or get the app from this repository.

    Universal Bypass
    Don't waste your time with compliance. Universal Bypass circumvents annoying link shorteners. Universal Bypass bypasses templates that are used on thousands of domains and it would be impossible for me to keep a complete list of domains that are bypassed. You would have to get a new Universal Bypass version and accept its new permissions for each new bypass. Custom Bypasses would be pretty pointless if you could only create them for sites that are already bypassed. Also known in the options as "Give and take the destinations of unbypassable shorteners.", this feature exists to bypass a respectable amount of link shorteners using CAPTCHAs and other forms of backend validation to make sure you've actually waited before you can proceed to the target link, to share this target with other Universal Bypass users, who come across the same link in the future, so they can proceed to the target immediately.

    Edpuzzle Answers

    Edpuzzle Answers

    A Javascript bookmarklet that can get the answers for Edpuzzle

    Edpuzzle Answers is a JavaScript-based bookmarklet and script toolkit designed to interact with Edpuzzle assignments by automating video playback and extracting answer data from embedded questions.

The tool can retrieve answers for multiple-choice questions, automate responses, and adjust playback settings, effectively streamlining the completion of assignments. It also includes functionality to skip video segments and prevent interruptions such as auto-pausing when switching tabs. The project supports integration with platforms like Canvas and Schoology where Edpuzzle content may be embedded. Additionally, it provides a lightweight graphical interface and optional backend support for more advanced features such as AI-assisted responses.

    Node.js

    Cross-platform JavaScript runtime environment

    Node.js is a free, open-source, cross-platform JavaScript runtime environment that allows developers to run JavaScript outside of the browser. It is built on Chrome’s V8 engine and is designed for building fast, scalable network applications.

    Selenium

    Selenium

    Browser automation framework and ecosystem

    Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should) also be automated as well. If you want to create robust, browser-based regression automation suites and tests, scale and distribute scripts across many environments, then you want to use Selenium WebDriver, a collection of language specific bindings to drive a browser - the way it is meant to be driven. If you want to create quick bug reproduction scripts, create scripts to aid in automation-aided exploratory testing, then you want to use Selenium IDE; a Chrome and Firefox add-on that will do simple record-and-playback of interactions with the browser. If you want to scale by distributing and running tests on several machines and manage multiple environments from a central point.

    AnduinOS

    AnduinOS

    AnduinOS is a custom Ubuntu-based Linux distribution

    AnduinOS is a personal/experimental operating system–style project and collection of components built to explore how a desktop-like environment and tooling could be organized under one coherent repo. It combines configuration, scripts, and UI elements to form a workstation experience that is more opinionated and automation-friendly than a vanilla setup. The project leans toward developer productivity: quick access to tools, reproducible configuration, and a unified place to evolve the environment. Because it is open source, users can inspect how the author wires services, handles packaging, or defines UI/UX conventions. It’s well suited for people who want to understand how to bootstrap and maintain a bespoke, code-driven desktop environment rather than relying on distro defaults. Over time it can serve as a living example of infrastructure-as-code principles applied to a personal OS setup.

    Bootstrap Icons

    Bootstrap Icons

    Open source SVG icon library for Bootstrap

    Free, high-quality, open-source icon library with over 1,600 icons. Include them any way you like, SVGs, SVG sprite, or web fonts. Use them with or without Bootstrap in any project. Bootstrap Icons are published to npm, but they can also be manually downloaded if needed. Bootstrap Icons are SVGs, so you can include them into your HTML in a few ways depending on how your project is setup. We recommend using a width: 1em (and optionally height: 1em) for easy resizing via font-size. Embed your icons within the HTML of your page (as opposed to an external image file). Here we’ve used a custom width and height. Use the SVG sprite to insert any icon through the <use> element. Use the icon’s filename as the fragment identifier (e.g., toggles is #toggles). SVG sprites allow you to reference an external file similar to an <img> element, but with the power of currentColor for easy theming.

    Claude-Mem

    Claude-Mem

    Claude Code plugin that automatically captures everything Claude does

    Claude-Mem is a persistent memory compression system built specifically for Claude Code to preserve context across coding sessions. It automatically captures Claude’s tool usage, observations, and decisions, then compresses them into semantic memories that carry forward into future sessions. By enabling long-term continuity, Claude-Mem helps Claude “remember” project history, past fixes, and prior reasoning even after restarts or reconnects. Its progressive disclosure approach intelligently injects only the most relevant context, balancing usefulness with token efficiency. Claude-Mem runs automatically in the background with no manual workflow changes required. Designed for serious developers, it transforms Claude Code into a continuously learning, project-aware coding assistant.
