    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.

    Tailwind CSS

    Tailwind CSS

    A utility-first CSS framework for rapid UI development

    Rapidly build modern websites without ever leaving your HTML. A utility-first CSS framework packed with classes like flex, pt-4, text-center and rotate-90 that can be composed to build any design, directly in your markup. Utility classes help you work within the constraints of a system instead of littering your stylesheets with arbitrary values. They make it easy to be consistent with color choices, spacing, typography, shadows, and everything else that makes up a well-engineered design system. Because Tailwind is so low-level, it never encourages you to design the same site twice. Even with the same color palette and sizing scale, it's easy to build the same component with a completely different look in the next project. Tailwind automatically removes all unused CSS when building for production, which means your final CSS bundle is the smallest it could possibly be. In fact, most Tailwind projects ship less than 10kB of CSS to the client.

    AngularJS

    AngularJS

    AngularJS - HTML enhanced for web apps

    AngularJS is a discontinued, open-source JavaScript framework by Google designed to extend HTML for building powerful single-page applications using MVC or MVVM patterns, offering data binding, dependency injection, and testability to simplify development. AngularJS lets you write client-side web applications as if you had a smarter browser. It lets you use good old HTML (or HAML, Jade/Pug and friends!) as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. It automatically synchronizes data from your UI (view) with your JavaScript objects (model) through 2-way data binding. To help you structure your application better and make it easy to test, AngularJS teaches the browser how to do dependency injection and inversion of control.

    UIkit

    UIkit

    Lightweight modular front-end framework for developing web interfaces

    A lightweight and modular front-end framework for developing fast and powerful web interfaces. UIkit will work on pretty much any modern browser. Using UIkit works best if you have a solid code editor, for example Sublime Text or Atom. To be even more efficient, we recommend that you install one of the autocomplete plugins for your favorite IDE or code editor. This saves a lot of time, as you won't have to look up and type all UIkit classes and markup. To use UIkit's CSS and JavaScript, include the files in your own HTML and then create the markup of any of the components. When you have installed UIkit with Less sources, you can compile it and add your own custom theme. Less is the language that the UIkit styles are written in. This allows you to include customizations in the build process, rather than manually overwriting a lot of CSS rules by hand.

    Fabric

    Fabric

    Fabric is an open-source framework for augmenting humans using AI

    Fabric is a command-line framework that turns a curated library of prompt “patterns” into reusable, automatable workflows for large language models. Instead of repeatedly crafting ad-hoc prompts, you pick a pattern (for research, summarization, brainstorming, code review, and more) and feed it inputs or files. The tool standardizes execution with configuration files and environment variables, enabling reproducible runs across different models and providers. Patterns can be customized with variables, chained into pipelines, and applied to entire directories, which helps scale editorial or analytical tasks. A growing catalog of community patterns serves as a knowledge base for effective prompt engineering in practical contexts. In short, Fabric makes LLM work predictable and scriptable, so teams can share methods rather than one-off prompts.
