Learn how leading tools help achieve WCAG compliance through automated scans, manual testing, and real-device validation.
Essential Tools for WCAG Remediation and Web Accessibility Testing

WCAG remediation is the process of finding and fixing accessibility issues to ensure websites and applications meet WCAG standards and are usable by people with disabilities.

WCAG remediation tools play a crucial role in detecting accessibility barriers and guiding teams through resolution. These tools support both automated scans and manual audits across real-world environments.

Why WCAG Remediation Tools Matter:

  • Ensure compliance with global accessibility standards like ADA, AODA, and EN 301 549
  • Improve digital access for users with visual, auditory, motor, or cognitive impairments
  • Minimize legal exposure and protect brand reputation
  • Boost SEO and overall user satisfaction

This article explores the top WCAG remediation tools available today, their features, pros and cons, and best practices for selecting and using them effectively.

What is WCAG?

The Web Content Accessibility Guidelines (WCAG) are global standards created by the W3C to make digital content accessible to people with disabilities.

They form the baseline for most accessibility laws, including ADA, AODA, and Section 508.

WCAG is built on four principles: Perceivable, Operable, Understandable, and Robust (POUR).
It defines three levels of compliance:

  • Level A: Basic accessibility
  • Level AA: Legal and industry standard
  • Level AAA: Most advanced level, not always required

Why is WCAG Important?

WCAG is essential because it helps ensure equal access to websites and applications. It also plays a critical role in meeting legal requirements in many countries, such as the Americans with Disabilities Act (ADA) in the United States and the Accessibility for Ontarians with Disabilities Act (AODA) in Canada.

Failing to comply with WCAG can lead to:

  • Accessibility lawsuits and legal risks
  • Poor user experience for individuals using assistive technologies
  • Reputational and financial damage

Meeting WCAG compliance offers several benefits like:

  • Broader reach and inclusive user experiences
  • Improved SEO and site usability
  • Stronger alignment with global accessibility laws

Meeting WCAG standards is essential for creating accessible, user-friendly, and legally compliant digital experiences.

What is WCAG Remediation?

WCAG remediation is the process of fixing accessibility issues in digital content to meet the Web Content Accessibility Guidelines (WCAG).

This includes addressing problems like poor color contrast, missing alt text, inaccessible forms, and broken keyboard navigation.

The goal is to make content accessible and legally compliant, typically targeting WCAG 2.1 Level AA. Depending on the issue’s complexity, remediation may be manual, automated, or both

Why Use WCAG Remediation Tools?

Manual remediation can be time-consuming and error-prone, especially for large websites or apps. 

WCAG remediation tools streamline this process by automating the detection, prioritization, and sometimes even correction of accessibility issues.

Key benefits of using these tools include:

  • Fast Issue Detection: Scan thousands of pages quickly and flag WCAG violations, categorized by severity and compliance level.
  • Clear, Actionable Guidance: Get code-level suggestions and visual highlights to resolve specific accessibility issues.
  • Continuous Testing: Integrate into CI/CD pipelines for automated checks with every deployment, ensuring accessibility.
  • Higher Accuracy: Catch errors often missed manually, like missing ARIA roles or broken tab sequences.
  • Enterprise Scalability: Standardize accessibility checks across multiple teams, regions, and digital assets with centralized dashboards.
  • Audit-Ready Reporting: Export detailed compliance reports aligned with legal standards for reviews and client assurance.

Types Of Tools Available For WCAG Remediation

When it comes to fixing WCAG issues, no single tool covers everything. Different tools address different aspects of accessibility and are best used together for complete compliance. 

These tools broadly fall into the following categories:

  1. Automated Testing Tools: These tools scan websites and applications for WCAG violations. They offer quick insights and reports, but may miss context-specific issues.
  2. Manual Testing Tools: Used to validate and catch issues missed by automation, such as keyboard navigation, screen reader compatibility, and color contrast.
  3. Browser Extensions: Installed directly in browsers, these tools allow developers to test accessibility in real time during development and debugging.
  4. Screen Readers: Critical for understanding how users with visual impairments navigate content. They help identify labeling, focus order, and navigation issues.
  5. Accessibility Checker Tools: Comprehensive platforms that combine automated scans, manual checks, and code-level analysis to enforce WCAG standards across projects

Difference between WCAG Remediation Tools and WCAG Testing Tools

WCAG testing and remediation tools serve different roles in the accessibility process. While one identifies issues, the other focuses on resolving them.

  1. Purpose: WCAG testing tools detect accessibility violations, whereas WCAG remediation tools help fix them.
  2. Functionality: Testing tools scan websites and apps for non-compliance; remediation tools provide fixes or guide developers in resolving issues.
  3. Output: Testing tools generate detailed issue reports; remediation tools deliver code suggestions or apply automated corrections.
  4. Workflow Integration: Testing tools integrate with CI/CD pipelines and dev environments; remediation tools often tie into design systems or content management platforms.
  5. User Focus: Testing tools are used during audits and QA; remediation tools assist developers, designers, and content teams in implementation.

How To Implement And Monitor WCAG Compliance Using Tools

WCAG compliance is not a one-time task. It requires ongoing testing, tracking, and improvement across your digital ecosystem.

Steps to implement and monitor WCAG compliance:

  1. Set Accessibility Goals: Decide on your target WCAG level and understand legal requirements like ADA, AODA, or EN 301 549.
  2. Select the Right Tools: Based on your needs, choose a combination of scanners (Lighthouse, Pa11y), screen readers (NVDA, JAWS), and platforms (BrowserStack Accessibility Testing).
  3. Integrate into Development: To catch issues early, add accessibility checks to design reviews, development cycles, and CI/CD pipelines.
  4. Audit Regularly: Run scheduled scans and manual tests on new and existing content. Use tools with history tracking and issue management.
  5. Fix and Validate Issues: Address high-priority problems and re-test fixes using automation and manual methods, including keyboard and screen reader testing.
  6. Track Progress: Monitor compliance over time using dashboards and exportable reports. These support internal reviews and external audits.

Pro Tip: Build accessibility into your culture by training teams and updating tools as WCAG standards evolve.

Best Practices For Using WCAG Remediation Tools

Effective remediation requires a consistent, scalable approach. Here are key practices to ensure long-term accessibility compliance:

  • Combine Automated and Manual Testing: Automated tools flag common issues, but manual checks are essential for screen reader support, focus order, and visual structure. BrowserStack Accessibility Testing supports both approaches on real browsers and devices.
  • Integrate Into CI/CD Workflows: Running accessibility checks during development and deployment helps catch issues early. Tools like BrowserStack integrate seamlessly with CI/CD pipelines.
  • Test With Real Devices And Assistive Tech: Validate usability using screen readers like NVDA and JAWSto ensure real-world accessibility, not just simulated behavior.
  • Track And Document Fixes: Use tools that generate reports and track issues. This supports accountability and simplifies audits.
  • Train All Stakeholders: Developers, designers, and QA teams should be trained on WCAG standards and tool usage.
  • Stay Aligned With Standards: Monitor WCAG updates and legal requirements to keep your compliance efforts current.

Conclusion

WCAG remediation is essential for building accessible and compliant digital experiences. The right tools simplify the detection and resolution of accessibility issues and support scale and accuracy.

Platforms like BrowserStack Accessibility Testing offer comprehensive features for teams needing reliable, cross-browser WCAG compliance.

By integrating accessibility into workflows and following best practices, teams can move beyond compliance to deliver inclusive, user-friendly experiences for all.
