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. -

BeEF
The browser exploitation framework project
BeEF is short for The Browser Exploitation Framework. It is a penetration testing tool that focuses on the web browser. Amid growing concerns about web-borne attacks against clients, including mobile clients, BeEF allows the professional penetration tester to assess the actual security posture of a target environment by using client-side attack vectors. Unlike other security frameworks, BeEF looks past the hardened network perimeter and client system, and examines exploitability within the context of the one open door: the web browser. BeEF will hook one or more web browsers and use them as beachheads for launching directed command modules and further attacks against the system from within the browser context. -

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. -

Water.css
A drop-in collection of CSS styles to make simple websites
water.css is a “classless” CSS framework that instantly beautifies plain HTML without adding custom classes to your markup. By targeting native HTML elements—headings, paragraphs, forms, tables, and buttons—it applies sensible defaults for spacing, typography, and contrast, producing a clean, readable layout out of the box. The stylesheet is intentionally small and dependency-free, making it a convenient drop-in for prototypes, documentation, and minimalist sites where heavy frameworks are overkill. It includes automatic dark and light themes and exposes CSS variables so you can adjust colors or spacing while keeping the overall aesthetic. Because it respects semantic HTML, it plays well with accessibility tools and reduces the risk of brittle component overrides. The result is a fast path to “good enough” styling that remains easy to customize when a project grows. -

7.css
A JS-independent, tree-shakeable CSS framework
7.css is a CSS framework for building interface components that look like Windows 7. It is built on top of the GUI backbone of XP.css, which is an extension of 98.css. This framework relies on the usage of semantic HTML. To make a button, you'll need to use a button. Input elements require labels. Tabs rely on the role="tab" attribute. This page will guide you through that process, but accessibility is a primary goal of this project. It does not ship with any JavaScript, so it is compatible with your frontend framework of choice. -

Alpine.js
A rugged, minimal framework for composing JavaScript behavior
Alpine.js is a lightweight JavaScript framework designed to bring declarative, reactive behavior directly into HTML markup, functioning similarly in spirit to Vue but with a much smaller footprint. It’s often described as “jQuery for the modern web,” enabling you to sprinkle interactivity onto static HTML without needing a full SPA framework. You use directives like x-data, x-bind, x-on, x-if, and others to attach reactive state, event listeners, and conditional rendering straight in the DOM. Because Alpine is so minimal, it avoids virtual DOM overhead and focuses on being incremental and composable; you can use it for small interactive components inside traditional server-rendered pages. The project has grown a robust ecosystem (plugins, devtools, helper libraries) as people adopt it for micro-frontend patterns, admin panels, interactive widgets, and anything that benefits from having bits of reactivity without a heavy JavaScript framework. -

Gantry Framework
Next Generation Template / Theme Framework
Develop CMS themes quickly and efficiently while providing flexibility and ease of use for end-users. Gantry was born when the RocketTheme development team wanted to consolidate our extensive set of custom Grav, Joomla and WordPress theme functionality into a simple, easy-to-use framework. Yes, that’s right! Gantry 5 has a powerful and easy-to-use Layout Manager that ensures controlling the layout is a highly visual experience. When we started the Gantry 5 project, we wanted to think past the concept of Gantry as a framework. We wanted to create something so versatile and powerful, that it could stand on its own as a platform, virtually independent of a CMS in concept and implementation. Utilizing a dual MIT & GPL license, Gantry is free to use pretty much anywhere! Designed from the ground-up with performance and efficiency in mind. Configure and structure your menu hierarchy with our new Menu editor. -

MediaElement.js is a set of custom Flash plugins that mimic the HTML5 MediaElement API for browsers that don't support HTML5 or don't support the media codecs you're using. Instead of using Flash as a fallback, Flash is used to make the browser seem HTML5 compliant and enable codecs like H.264 (via Flash) on all browsers. In general, MediaElement.js supports IE11+, MS Edge, Chrome, Firefox, Safari, iOS 8+ and Android 4.0+. It is strongly recommended to read the entire documentation and check the demo folder to get the most out of this package. -
