Cubic Bezier
cubic-bezier.com
An interactive cubic bezier curve editor for crafting custom CSS animation timing functions — drag the control points, compare against built-in easings, and copy the resulting CSS cubic-bezier() value.
Why it is useful
Makes the relationship between bezier control points and animation feel intuitive rather than abstract. The side-by-side comparison with standard easing functions (ease, ease-in, ease-out) helps you quickly find curves that are subtly different from defaults. Custom bezier timing functions make animations feel noticeably more polished; this tool is the fastest way to find the right one.
