What is the difference between WCAG, ADA, and Section 508?

WCAG is the global standard. ADA is US law. Section 508 applies to US federal agencies. Pcloudy covers all three in a single scan.

Why is real device testing better than emulators?

Screen readers behave differently on real hardware. Real device testing captures actual user experience including touch patterns and native announcements.

What checks does axe-core automate?

axe-core automates 90+ WCAG rules covering contrast, ARIA, keyboard, alt text, headings, forms, landmarks, and more.

Can I use accessibility testing in CI/CD?

Yes. Pcloudy integrates with Jenkins, GitHub Actions, GitLab CI, and more. Set thresholds and block non-compliant merges automatically.

How is Pcloudy different from browser extensions?

Pcloudy runs axe-core at scale across 5,000+ real devices plus adds real screen reader testing on mobile that extensions cannot do.

Does Pcloudy support mobile app accessibility testing?

Yes. Test with VoiceOver and TalkBack on real Android and iOS devices, validate touch targets, and check platform-specific accessibility APIs.

Web Accessibility Testing Tools — WCAG & ADA

Why Web Accessibility Testing Matters

1B+ people live with disabilities. Inaccessible apps exclude users and create legal risk.

Manual audits are slow, inconsistent, and miss critical issues at scale

Emulators can't replicate real screen reader behavior on actual devices

WCAG & ADA violations found post-launch lead to lawsuits and costly fixes

axe-core-powered WCAG scans across every browser — violations caught in seconds

Real-device screen reader testing with VoiceOver & TalkBack on actual mobile hardware

CI/CD accessibility gates block non-compliant code before production

How to Test Accessibility of a Website

From WCAG scanning to screen reader validation — here's how to test accessibility of a website with Pcloudy in four steps.

Launch Browser Session

Pcloudy spins up a real browser on cloud infrastructure and loads your page.

Inject axe-core & Scan

axe-core is injected via CDN, runs 90+ WCAG rules, and returns violations with rule IDs & impact levels.

Screen Reader on Mobile

Run VoiceOver (iOS) & TalkBack (Android) on real devices to validate announcements.

Report & Gate in CI/CD

Get per-violation details (id, description, impact) and block non-compliant PRs automatically.

Accessibility Testing FAQ

Web accessibility testing evaluates websites and apps to ensure they are usable by people with disabilities. Pcloudy uses axe-core for automated web WCAG audits and real-device screen readers (VoiceOver & TalkBack) for mobile validation — covering contrast, keyboard, ARIA, and compliance across 5,000+ devices.

Run an axe-core WCAG scan to check all success criteria across browsers, validate with real screen readers on mobile devices, review the accessibility testing checklist WCAG requires, and integrate into your CI/CD pipeline. Pcloudy handles all four steps.

WCAG is the global standard with Levels A, AA, and AAA. ADA is US law requiring accessible digital experiences. Section 508 applies to US federal agencies and contractors. Pcloudy covers all three standards in a single scan.

Screen readers behave differently on real hardware compared to emulators. Real device testing captures the actual user experience — including touch interaction patterns, native announcement behavior, and platform-specific accessibility APIs.

axe-core automates 90+ WCAG rules covering color contrast ratios, ARIA roles and attributes, keyboard operability, alt text, heading hierarchy, form labels, landmark regions, language attributes, table structure, list semantics, and touch target sizes (WCAG 2.2).

Yes. Pcloudy integrates with Jenkins, GitHub Actions, GitLab CI, CircleCI, and more. Set WCAG compliance thresholds and automatically block merges when violations are detected.

Contrast ratios (4.5:1 for AA), keyboard operability, screen reader compatibility, heading hierarchy, alt text, focus management, ARIA landmarks, form labels, error identification, and skip navigation links.

Pcloudy uses the same axe-core engine that powers browser extensions — but runs it at scale across 5,000+ real devices and 3,000+ browser combos. Plus, it adds real screen reader testing on mobile devices that extensions simply can't do.

Yes. Test with VoiceOver and TalkBack on real Android and iOS devices, validate touch target sizes, and check platform-specific accessibility APIs.
