JavaScript animation engine

Generative, free-running animated fields for the terminal (rain, tunnel, ripple, galaxy) — a pure (width, height, frame) → ANSI engine. MIT.

A zero-config, drop-in animation utility that adds smooth transitions to your web app. You can use it with React, Vue, or any other JavaScript application.

Verifies & compiles reduced-motion-safe, on-budget UI animation for AI-generated web apps. Validated specs → deterministic GSAP/WAAPI-CSS; WCAG 2.2.2 + 2.3.3 checks. MIT core + keyless MCP server. Not Motion.dev/Framer Motion, not the Android/iOS MotionSpec classes, not a video generator.

Constraint-based adaptive rendering framework. Maps continuous signals (viewport, scroll, time, pointer) to discrete states via BoundaryDef primitives. Multi-target compilation to CSS @container queries, GLSL/WGSL uniforms, ARIA attributes. Effect v4 reactive runtime with hysteresis, blend trees, and content-addressed identity.

Create keyframe animations for anything in JavaScript

Native PHP GIF Encoder/Decoder

Programmatic video engine for the web — compile a declarative config into deterministic motion graphics and video (Three.js, GSAP, 2D, HTML). The open engine behind vos.so.

The first truly composable CSS animation library. Built for Vue, React, SCSS, and CSS, AnimXYZ will bring your website to life.
