A11yKit: 15 Free, Zero-Upload Accessibility & WCAG 2.2 / APCA Contrast Tools for Zustand Apps

[gstar-byte]

Hi Zustand community! 👋

Zustand is widely loved for its minimalistic and unopinionated state management. In modern accessible web applications, Zustand stores frequently orchestrate accessibility states — such as dark/light themes, high-contrast toggles, reduced-motion preferences, and focus-lock states across modal flows.

To help test and guarantee that visual UI states comply with WCAG 2.2 and the upcoming European Accessibility Act (EAA), 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 Zustand apps:

• Dynamic Theme & Contrast Audits: Validate contrast ratios (WCAG 2.1 & modern APCA) as your Zustand store transitions between theme palettes.
• Color Blindness Simulator: Ensure active toggle states, badges, and notification badges remain distinct across 8 vision deficiency models.
• WCAG 2.2 Target Size Verifier: Quickly verify interactive buttons, sliders, and switches satisfy minimum touch target guidelines (24x24px).
• Zero Server Uploads & Privacy-First: 100% client-side computation via Web Workers and WASM — safe for proprietary designs and enterprise codebases.
• Headless CI/CD Auditing: Add automated accessibility validation to GitHub Actions via pip install a11ykit-cli, npm install a11ykit-cli, or our official GitHub Action.
