A11yKit — 15 Free Accessibility Tools That Run in Your Browser
WCAG 2.2 compliance tools that never upload your data. 100% client-side.
A11yKit is a free accessibility toolkit with 15 tools: contrast checker, WCAG 2.2 checklist, ARIA generator, color blind simulator, URL scanner, and more. Everything runs in your browser — no uploads, no accounts, no tracking. Includes a Top 50 sites audit report.
Hey Product Hunt! 👋
I built A11yKit because every accessibility tool I found wanted to upload my HTML to their server. As a developer who cares about both privacy and accessibility, that felt wrong.
What's included:
- 🔍 URL Scanner — scan any website for WCAG 2.2 violations (axe-core powered)
- 🎨 Contrast Checker — WCAG AA/AAA + APCA scoring with color suggestions
- 🌈 Color Blind Simulator — 8 types, severity slider, Daltonize correction
- 🏷️ ARIA Generator — 20+ patterns with live HTML/JSX preview
- ✅ WCAG 2.2 Checklist — interactive, filterable, with progress tracking
- 📄 Accessibility Statement Generator — EAA-compliant templates, AI-powered
- 🖼️ AI Alt Text Generator — batch processing, multi-language
-
- 8 more tools
Why it's different:
- 100% client-side — your data never leaves your browser
- No accounts, no signup, no tracking
- PWA — works offline after first load
- Open source
Bonus: We also scanned 52 of the world's top websites for WCAG 2.2 compliance and published the results → https://a11ykit.site/accessibility-report
Spoiler: 70 violations found. WebMD had 7. Zoom had 6. Only 18 sites passed clean.
Would love your feedback! 🙏
Show HN: 15 free accessibility tools, 100% client-side, no data upload
I built a collection of 15 accessibility tools that all run entirely in the browser — no server-side processing, no data upload, no accounts.
Tools include:
- URL scanner (axe-core powered, scans any public URL)
- Color contrast checker (WCAG AA/AAA + APCA)
- Color blind simulator (8 types + Daltonize)
- ARIA role/attribute generator (20+ patterns)
- WCAG 2.2 compliance checklist
- Accessibility statement generator (EAA-compliant)
- AI alt text generator (uses your own OpenAI key)
- HTML scanner, heading analyzer, form label checker, link text checker, focus order checker, alt text checker, PDF checker, accessibility monitor
As part of the launch, I also ran axe-core WCAG 2.2 scans against 52 of the world's top websites and published the results[1]. Some findings:
- 70 total violations across 48 successfully scanned sites
- 95.7% were critical or serious severity
- Most common: color-contrast (9 sites), missing alt text (6 sites), empty link names (6 sites)
- Worst offenders: WebMD (7), Zoom (6), AliExpress (5), Spotify (5)
- 18 sites passed with zero violations (Google, Wikipedia, BBC, Microsoft, GitHub, Stripe, etc.)
Everything is open source and runs client-side. The scan report is at https://a11ykit.site/accessibility-report
[1] Automated tools catch ~30-40% of WCAG issues, so a clean scan doesn't mean a site is fully accessible. But it's a useful baseline.

Title: Launched an accessibility toolkit — 15 tools, zero server costs, plus a research report
Body:
Just launched A11yKit — 15 free accessibility tools that run entirely in the browser. Zero server-side processing means zero hosting costs beyond static file serving.
Built with Next.js + axe-core. Everything is client-side: contrast checking, color blind simulation, ARIA generation, WCAG checklist, URL scanning, and more.
To get some attention, I also scanned 52 of the world's top websites with axe-core and published a report. 70 violations found. WebMD was the worst with 7. 18 sites passed clean.
The report is already getting some traction — it turns out "Top 50 websites accessibility audit" is link bait that actually works.
