A11yKit: 15 Free, Zero-Upload Accessibility & WCAG 2.2 / Contrast Tools for Motion & UI Animations

[gstar-byte]

Hi Motion (Framer Motion) community! 👋

Motion makes building fluid, declarative web animations an absolute joy. At the same time, animation accessibility is a critical pillar of WCAG 2.2 (e.g. Success Criterion 2.2.2 Pause/Stop/Hide and 2.3.3 Reduced Motion for vestibular disorders). Furthermore, dynamic animations often shift element contrast against backgrounds and impact interactive target sizes during keyframe transitions.

We built A11yKit (https://a11ykit.site) — 15 free developer-focused accessibility utilities running 100% locally in the browser with zero server uploads.

How A11yKit complements Motion-powered UIs:

• Contrast & APCA Matrix Across Animation States: Validate color contrasts of text overlays against animated backgrounds, gradients, and backdrop blurs.
• WCAG 2.2 Target Size Verifier: Validate touch target dimensions on interactive animated buttons, drag handles, and layout transitions against the 24x24px minimum hit-area requirement.
• Color Blindness Simulation (8 Models): Ensure state indicators that transition color (e.g. green to red) remain completely distinguishable for color-deficient users.
• Zero Server Uploads & Privacy-First: 100% client-side computation via Web Workers and WASM — safe for confidential proprietary animations and design tokens.
• CI/CD Automation: Add automated accessibility checks to GitHub Actions using pip install a11ykit-cli, npm install a11ykit-cli, or our official GitHub Action.
