About this tool

Turn stiffness, damping, mass, and velocity into CSS cubic-bezier springs. Analytical damped motion, settle-time estimate, and live preview — free and client-side. CSS Spring Physics Generator runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.

What this tool does not do

  • CSS Spring Physics Generator is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
