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. -

Monaco Editor
A browser based code editor
Monaco Editor is the rich, browser-based code editor that powers Visual Studio Code, providing advanced editing capabilities as a standalone embeddable library for web applications. Models are at the heart of Monaco editor. It's what you interact with when managing content. A model represents a file that has been opened. This could represent a file that exists on a file system, but it doesn't have to. For example, the model holds the text content, determines the language of the content, and tracks the edit history of the content. An editor is a user facing view of the model. This is what gets attached to the DOM and what your users see visually. Typical editor operations are displaying a model, managing the view state, or executing actions or commands. -

WebTorrent
Streaming torrent client for the web
WebTorrent is a streaming torrent client for node.js and the browser. YEP, THAT'S RIGHT. THE BROWSER. It's written completely in JavaScript – the language of the web – so the same code works in both runtimes. In node.js, this module is a simple torrent client, using TCP and UDP to talk to other torrent clients. In the browser, WebTorrent uses WebRTC (data channels) for peer-to-peer transport. It can be used without browser plugins, extensions, or installations. It's Just JavaScript™. Note: WebTorrent does not support UDP/TCP peers in browser. To make BitTorrent work over WebRTC (which is the only P2P transport that works on the web) we made some protocol changes. Therefore, a browser-based WebTorrent client or "web peer" can only connect to other clients that support WebTorrent/WebRTC. -

Blockly Games
Games for tomorrow's programmers
Blockly Games is a collection of educational games that teach core programming concepts using Google’s Blockly visual blocks. Each game introduces ideas like sequencing, loops, conditionals, functions, and variables through playful puzzles that gradually increase in difficulty. Under the hood, the block programs compile to JavaScript, giving learners a bridge from drag-and-drop logic to real code. The activities are self-contained and browser-based, requiring no installation, which makes them suitable for classrooms and workshops. Progression is scaffolded: earlier levels constrain the toolset, while later levels unlock more expressive blocks and optional textual views. The project’s emphasis on immediate visual feedback and forgiving iteration lowers the barrier for first-time programmers while still rewarding mastery. -
