    Superpowers Framework

    Superpowers Framework

    An agentic skills framework & software development methodology

    Superpowers Framework is a widely-used agentic skills framework and methodology for software development that equips coding agents like Claude Code with structured capabilities to plan, develop, test, and review code systematically. Instead of simply generating code, Superpowers drives an AI through a thoughtful software engineering workflow that starts with clarifying project intent, teasing out a detailed specification, and creating an implementation plan that is readable and actionable. It incorporates test-driven development, task planning, and sub-agent orchestration so that each engineering task is executed, checked, and iterated upon with rigor rather than ad-hoc improvisation. Superpowers includes a rich set of modular “skills” that guide the AI in areas such as brainstorming, planning, debugging, and code review, giving it the tools to function like a disciplined developer rather than a naive auto-completer.

    SurveyJS

    JavaScript Survey and Form Library

    SurveyJS Form Library is distributed as npm packages and as scripts and style sheets that you can reference on your page. You can use it in any React, Angular, Vue, Knockout, or jQuery application. React, Angular, Knockout, and Vue3 are supported natively. To communicate with the server, the libraries use JSON objects that represent form schemas (content and layout of a form) and form results (answers). You have the option to build dynamic JSON-driven forms using our free full-featured form builder demo available on the website. Alternatively, you can integrate the form builder library and create forms using a drag-and-drop UI directly within your own application. With years of development and support behind us, we've assisted hundreds of companies across various industries. With Survey, you can create nearly anything that popular cloud services offer. Furthermore, our library is fully extensible, allowing you to modify its behavior to suit your specific needs.

    Tracing Framework

    Tracing Framework

    Web Tracing Framework libraries and extensions

    The Web Tracing Framework (WTF) is an open source suite of tools, libraries, and visualizers created by Google to help developers analyze and optimize the performance of complex web applications. By adding lightweight instrumentation to their code, developers can trace execution flow, identify bottlenecks, and detect performance regressions. The framework provides fine-grained insights into application behavior, making it particularly useful for achieving smooth, high-performance experiences, such as maintaining 60fps animations in web interfaces. It includes visualization tools that allow for detailed analysis of timing, resource usage, and event flow, enabling developers to diagnose and fix inefficiencies effectively. While still experimental, WTF is designed to be extensible and community-driven, encouraging contributions and adaptations for various types of web applications.

    Tree Style Tab

    Tree Style Tab

    Tree Style Tab, Show tabs like a tree.

    This extension to Firefox provides the ability to work with tabs as "trees". New tabs opened from the current tab are automatically organized as "children" of the current tab. Such "branches" are easily folded (collapsed) by clicking on the arrow shown in the "parent" tab, so you no longer need to suffer from too many visible tabs. If you want, you can restructure the tree via drag and drop. Such a tree of tabs will behave like a visual browsing history for you. For example, if you see a list of search results for a topic, each search result link will open in new child tab. New tabs opened from these "child" tabs will appear as descendants of their originating tabs. You'll easily dig and dig deeply, without losing your browsing trail - if you want to go back to the original search result, you just have to switch to the "root" tab. Moreover, each tree will reflect a group of tabs on a similar topic.

    Serverless WebRTC matchmaking for painless P2P: make any site multiplayer in a few lines. Trystero manages a clandestine courier network that lets your application's users talk directly with one another, encrypted and without a server middleman. To establish a direct peer-to-peer connection with WebRTC, a signalling channel is needed to exchange peer information (SDP). Typically this involves running your own matchmaking server but Trystero abstracts this away for you and offers multiple "serverless" strategies for connecting peers (currently BitTorrent, Firebase, and IPFS).

    UglifyJS 3

    UglifyJS 3

    JavaScript parser, mangler, compressor, beautifier toolkit

    UglifyJS is a JavaScript compressor/minifier written in JavaScript. It also contains tools that allow one to automate working with JavaScript code. A parser which produces an abstract syntax tree (AST) from JavaScript code. A code generator which outputs JavaScript code from an AST, also providing the option to get a source map. A compressor (optimizer). it uses the transformer API to optimize an AST into a smaller one. A mangler, reduce names of local variables to (usually) single-letters. A scope analyzer, which is a tool that augments the AST with information about where variables are defined/referenced etc. A tree walker, a simple API allowing you to do something on every node in the AST. A tree transformer, another API intended to transform the tree. All the above utilities and APIs are defined in ~6500 lines of code (except for the effective generation of the source-map, which is handled by the source-map module). Compared to alternatives, UglifyJS is pretty small.

    Vulcan

    Vulcan

    A toolkit to quickly build apps with React, GraphQL & Meteor

    Vulcan is a framework that gives you a set of tools for quickly building React & GraphQL-based web applications. It can handle data loading, e-mail notifications, automatic form generation, and much more, out of the box. Vulcan is unique in that it spans the full-stack, from the database to the browser. While there exist many excellent back-end frameworks or backend-as-a-service providers, these all still require you to handle the front-end code yourself, including building a set of components to read, write, and display data. However, being full-stack, Vulcan is able to speed up these repetitive tasks by providing a whole range of helper components that are fine-tuned to the Vulcan back-end, and as a result just work out of the box. In order to make working with Vulcan easier (especially when it comes to updating the core packages), you are also free to follow the more complicated “two-repo” pattern, with the two repositories.
