three.js
JavaScript 3D library
three.js is a lightweight and easy-to-use JavaScript 3D library with its own default WebGL renderer. It works by creating a scene with a camera and a geometric cube, the latter of which is added to the scene. This will become the animated object within the scene. A WebGL renderer is created for the scene and the camera, with an added viewport to the document.body element. Finally, the cube is animated within the scene for the camera. A plethora of examples can be found in the project’s website (https://threejs.org/) which use Canvas 2D, SVG and CSS3D renderers that the library also provides. -

Velocity
Accelerated JavaScript animation
Velocity is an animation engine with the same API as jQuery's animate. It works with and without jQuery. It's incredibly fast, and it features color animation, transforms, loops, easings, SVG support, and scrolling. It is the best of jQuery and CSS transitions combined. Velocity works everywhere — back to IE8 and Android 2.3. Under the hood, it mimics jQuery's queue, and thus interoperates seamlessly with jQuery's animate, fade, and delay. Since Velocity's syntax is identical to animate, your code doesn't need to change. JavaScript and jQuery are falsely conflated. JavaScript animation, which Velocity uses, is fast; it's jQuery that's slow. Although Velocity works alongside jQuery, it uses its own animation stack that delivers its performance through two underlying principles: 1) synchronize the DOM → tween stack to minimize layout thrashing, and 2) cache values to minimize DOM querying. -

Typed.js
A JavaScript typing animation library
Typed.js is a library that types. Enter in any string, and watch it type at the speed you've set, backspace what it's typed, and begin a new sentence for however many strings you've set. Rather than using the strings array to insert strings, you can place an HTML div on the page and read from it. This allows bots and search engines, as well as users with JavaScript disabled, to see your text on the page. You can pause in the middle of a string for a given amount of time by including an escape character. CSS animations are built upon initialization in JavaScript. But, you can customize them at your will! -

lax.js
Library to create smooth & beautiful animations when you scroll
Simple & lightweight (<4kb gzipped) vanilla JavaScript library to create smooth & beautiful animations when you scroll. Lax.js 2.0 has been completely re-written with a focus on modularity and flexibility giving you more tools to create awesome animations. To implement lax you need to create at least one driver, to provide values for animations, as well as the element animation bindings. The easiest way to get started is to use presets via html classes. Multiple presets can be chained together and they can be customised to suit your needs. Use the preset explorer to explore effects and see a simple example here. To increase performance, lax.js indexes the list of elements to animate when the page loads. If you're using a library like React, Vue or EmberJS, it is likely that you are adding elements after the initial window.onload. Because of this you will need to call lax.addElements when you add components to the DOM that you want to animate. -

Animatable
One property, two values, endless possiblities
Animatable is an interactive web gallery that demonstrates which CSS properties can transition between two values. Each tile represents one property and continuously alternates between a defined starting and ending state. Visitors can animate every example at once or trigger individual demonstrations by hovering. Selecting a tile reveals the property name, both values, authorship information, and controls for moving to adjacent examples. Keyboard navigation supports Escape and the arrow keys for faster exploration. The page generates its keyframes dynamically with JavaScript and applies compatibility fixes through StyleFix. It serves as a visual reference and experimental showcase rather than a general-purpose animation library. -

CSS Loaders
A collection of loading spinners animated with CSS
css-loaders is a collection of simple, reusable loading spinners and indicators implemented entirely in CSS. The project offers a variety of designs—spinning circles, bouncing dots, bars, and pulse animations—that can be applied to any element with a few classes. Each loader is built using CSS keyframes and transforms, avoiding images or JavaScript, which keeps them lightweight and responsive. Because they are pure CSS, they scale cleanly at different sizes and can be styled easily with color or shadow overrides. Developers can copy snippets directly into their projects without needing to install heavy dependencies. These loaders are widely used in web apps and prototypes to communicate background activity or waiting states to users in a visually pleasing way. -

Christmas Tree
Just a simple Christmas tree, based on reddit story
atree is a lightweight JavaScript library for managing and visualizing hierarchical tree data structures in a flexible and efficient way. It offers core abstractions for creating nodes, building parent–child relationships, and traversing trees with utilities for depth, breadth, and custom iteration strategies. Because tree structures are ubiquitous in computing—from file systems and organizational charts to DOM structures and evolutionary taxonomies—atree provides a reusable foundation for representing and interacting with nested data. It separates the logical model from rendering concerns, so you can use it as the data backbone in UI frameworks, graphs, or custom visual components. The library’s API makes it easy to add, remove, or move nodes anywhere in the hierarchy while maintaining consistent references and performance. -

Effeckt.css
A Performant Transitions and Animations Library
Effeckt.css is a showcase and toolkit of high-performance UI transitions and animations for the web. It catalogs common interaction patterns—button states, list reveals, modals, off-canvas menus, and page transitions—implemented with CSS transforms and opacity for smooth, GPU-friendly motion. The project focuses on practical details such as using compositing-friendly properties, keeping DOM structures lean, and providing hooks so JavaScript can toggle classes without micromanaging animation state. Each effect is isolated, documented, and demoed, allowing designers to copy just what they need rather than dragging in a monolithic framework. By standardizing names and behaviors, it helps teams keep motion design consistent across a product while remaining easy to theme. The library doubled as a learning resource during the rise of CSS animations, showing how to achieve polished interactions without heavy JavaScript. -

Loaders.css
Delightful, performance-focused pure css loading animations
loaders.css is a collection of pure CSS loading animations designed to drop into any web project without JavaScript or image assets. Each loader is built from simple HTML elements animated with CSS keyframes, transforms, and opacity to create spinners, pulses, bars, and geometric patterns. Because they’re vector-based and CSS-driven, the animations scale cleanly at any resolution and look sharp on high-DPI displays. The library emphasizes small, reusable snippets: you copy a minimal markup block, apply the provided class, and tweak size or color through CSS variables or overrides. Animations are crafted to be smooth and performant, relying on GPU-friendly properties to keep frame rates high even on mobile devices. The set covers common loading metaphors (pulsing dots, rotating squares, bouncing bars), giving designers a consistent visual language across a site while keeping bundle size tiny. -

Lottie-Web
Render After Effects animations natively
Lottie-Web renders vector animations exported from Adobe After Effects as lightweight JSON, playing them in the browser via SVG or Canvas. Animations remain crisp at any resolution, load quickly compared to videos or GIFs, and can be controlled programmatically for interactivity. The runtime supports playback options like loop, autoplay, segment control, and event hooks, making it easy to sync motion with UI state. Because animations are data rather than pixels, designers and developers can collaborate: designers export with the Bodymovin plugin, and developers integrate the JSON with minimal code. The renderer handles masks, shapes, and keyframe timing to closely mirror After Effects behavior within web constraints. This approach brings high-quality motion design to product interfaces without large asset sizes or complex sprite workflows. -

MilkDrop Anywhere
A remote control MilkDrop2 plugin for Windows
Allows you to easily remote control MilkDrop2 VJ Console in Winamp (Windows only) via graphic interface from any browser (via tablet or cellphone perhaps). You must have Apache2 (or any webserver) with PHP 5.4+ running on the same computer Winamp is running on and some basic knowledge of how that all works. Once you've got everything set up and running, it should run near flawlessly (I was using it for a few hours continuously once with no hiccups) There's a readme.txt file inside the zip file with some basic instructions. Check out the Wiki or Discussion tab for up to date instructions, info, and more... If anyone actually uses this, please let me know in the Discussion tab - I don't know if the interest would be that high this day and age but you never know... If you're a programmer, you could tweak this program as a template to remotely control anything you want (just give me some credit, I wrote it from scratch) Not a 100% easy setup, but anyone can do it!
