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. -

AsyncAPI
Allows you to create machine-readable definitions of asynchronous APIs
AsyncAPI is an open-source initiative that seeks to improve the current state of Event-Driven Architecture (EDA). Our long-term goal is to make working with EDAs as easy as working with REST APIs. That goes from documentation to code generation, from discovery to event management, and beyond. The AsyncAPI Specification defines a standard, protocol-agnostic interface that describes message-based or event-driven APIs. The AsyncAPI document allows people or machines communicating with one another to understand the capabilities of an event-driven API without requiring access to the source code, documentation, or inspecting the network traffic. It allows you to define your API structures and formats, including channels the end user can subscribe to and the message formats they receive. You can develop, validate, and convert the AsyncAPI document to the latest version or preview your AsyncAPI document in a more readable way using the AsyncAPI Studio. -

This repository provides a set of hands-on CSS exercises that accompany the HTML and CSS modules in The Odin Project curriculum. The tasks are designed to be completed at specific points in the course, reinforcing each concept right after it is introduced. Learners are encouraged to use documentation and external resources freely, reflecting real-world workflows rather than rote memorization. Each exercise focuses on practical styling problems, from selectors and specificity to layout techniques like flexbox, grid, and responsive design. The structure supports incremental learning, allowing you to test your understanding, compare against expected outcomes, and iterate until styles match the intended result. While solutions exist, the guidance emphasizes problem solving with docs, search, and experimentation before peeking, cultivating independent debugging skills and confidence with CSS.

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. -

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. -

Chokidar
Minimal and efficient cross-platform file watching library
Chokidar is a solution for all the users of Node.js fs.watch who are tired of it not reporting filenames on MacOS and events at all when using editors like Sublime on MacOS. Node.js fs.watch often reports events twice, emits most changes as rename, and it does not provide an easy way to recursively watch file trees nor supports recursive watching on Linux. Same as with Node.js fs.watchFile. Therefore, Chokidar resolves these problems. Initially made for Brunch (an ultra-swift web app build tool), it is now used in Microsoft's Visual Studio Code, gulp, karma, PM2, browserify, webpack, BrowserSync, and many others. It has proven itself in production environments. Chokidar does still rely on the Node.js core fs module, but when using fs.watch and fs.watchFile for watching, it normalizes the events it receives, often checking for truth by getting file stats and/or dir contents. -

ClearURLs
ClearURLs is an add-on based on the new WebExtensions technology
ClearURLs is an add-on based on the new WebExtensions technology and is optimized for Firefox and Chrome-based browsers. This extension will automatically remove tracking elements from URLs to help protect your privacy when browsing through the internet. For this purpose, we use a large catalog of rules, which is actively maintained by us and the community. Many websites use tracking elements in the URL to mark your online activity. All that tracking code is not necessary for a website to be displayed or work correctly and can therefore be removed, that is exactly what ClearURLs does. Prevents Google from rewriting the search results (prevents the insertion of tracking code). Prevents Yandex from rewriting the search results (prevents the insertion of tracking code). Prevents tracking injection over history API. -

Comprehensive Rust
This is the Rust course used by the Android team at Google
Comprehensive Rust is an open source training course developed by Google to provide a complete introduction to the Rust programming language. Originally created for Google engineers, it has since been released publicly for the broader developer community. The course is structured into modular lessons that cover the fundamentals of Rust, including ownership, lifetimes, traits, generics, and error handling, before progressing to advanced topics like concurrency, async programming, unsafe Rust, and FFI. It is designed to be taught in classroom settings but can also be followed independently, making it useful both for structured training and self-study. The materials are presented in a slide-based format with accompanying examples and hands-on exercises to reinforce key concepts. By offering an accessible yet thorough introduction, the course helps learners gain practical experience with Rust while building a strong understanding of its unique safety and performance guarantees. -

Consola
Elegant Console Logger for Node.js and Browser
Fancy output with fallback for minimal environments. Consistent command-line interface (CLI) experience. Spam prevention by throttling logs. console uses std in the underlying so calling wrapStd redirects console too. The benefit of this function is that things like console.info will be correctly redirected to the corresponding type. Any instance of consola that inherits the mocked instance, will apply provided callback again. This way, mocking works for withTag scoped loggers without the need for extra effort. Choose between one of the built-in reporters or bring in your own one. By default FancyReporter is registered for modern terminals or BasicReporter will be used if running in limited environments such as CIs. A reporter (class or object) exposes log(logObj) method. To get more info about how to write your own reporter, take a look at the linked implementations. -
