Design transition timing functions with live motion comparison runners and copyable classes.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Choose from Apple Smooth, Spring Bounce, or fine-tune X1, Y1, X2, Y2 coordinates.
Click Test Animation to see your custom timing curve race against standard linear easing.
Copy the standard transition property rule or the Tailwind arbitrary ease-[...] class.
Cubic-bezier curves define the velocity curve of a transition using four control points between (0,0) and (1,1), dictating acceleration and deceleration over time.
Yes! Setting Y1 or Y2 values greater than 1.0 or less than 0.0 creates spring bounce and overshoot animation effects.
