How does that site feel so good?

easeprint is a Chrome extension that reads the motion on whatever page you're on. You get the curves and durations the site actually uses, drawn as one print, and you can copy them straight into CSS, Tailwind, Motion or SwiftUI.

Download for Chrome How to install

Values are read from what the browser computed, so they're exact. Motion driven from JavaScript gets fitted from its frames and is marked that way. Free, and it only reads a page after you click it.

Reading a print

Each ridge is one timing the site uses. Short, snappy ones sit near the core and slow ones sit further out, so a quick site makes a tight print.

A ridge bulges where its curve runs ahead of the clock. An ease-out swells early, an ease-in late, and an overshoot pushes out past its neighbours.

Thicker ridges showed up more. Broken ones are loops. The faint lines between are filled in from their neighbours so the whole thing reads as one surface.

Measured in a browser on 2026-10-17. 105 tiers, and 6 of 20 sites honor reduced motion. Hover a print and it draws itself on that site's own lead curve.

Install it

It isn't on the Chrome Web Store yet, so for now it installs by hand. Takes about a minute.

1
Download the zip and unzip it.
2
Open chrome://extensions, turn on Developer mode in the top right, and click Load unpacked. Pick the easeprint folder.
3
Go to a site you like and click easeprint in the toolbar, or press Alt Shift E. Move around the page and the print fills in.

It asks for nothing up front. Clicking it gives it the one tab you're on until you leave that page. Record from load asks for one site at a time. Nothing leaves your browser.
