Easely

Shape CSS easing curves you can feel, then copy the code.

Easely is a live cubic-bezier editor for CSS motion: drag two handles to shape an easing curve and watch a ball ride it in real time, with a tracer dot that follows the exact timing. Pick from nine presets, tune the duration, then copy a ready-to-paste cubic-bezier() value or the full transition-timing-function line. Built end-to-end with AI, it runs entirely in your browser with no login, and the whole single-file source is downloadable to self-host or remix.
