How it works
Get a motion-safety score
Motion Safe weighs autoplay, duration, flashing risk, and reduced-motion support against WCAG motion guidance.
Fix and re-test
Add pause controls, honor prefers-reduced-motion, and remove flashing, then re-check.

Frequently asked questions
What is prefers-reduced-motion?
A CSS media query that lets users signal at the OS level that they want reduced animation — respecting it is a core WCAG 2.3.3 practice.
Why is flashing flagged so heavily?
Content flashing more than 3 times per second can trigger seizures in people with photosensitive epilepsy (WCAG 2.3.1), so it's treated as a hard risk rather than a minor deduction.
Is some animation always bad?
No — purposeful, brief animation (under ~400ms) that supports understanding is fine. The risk is autoplay, long duration, and no way to opt out.

WAVE can scan a live page for some accessibility issues but doesn't focus on motion specifically. Manual QA catches nuance but is slow. Motion Safe gives a fast structured score from your own animation inventory.
