Clym Accessibility Scanner:
Free WCAG 2.2 & ADA Website Accessibility Testing Tool

An accessible website enables people with disabilities to use, navigate, and interact with its content effectively. It follows standards such as WCAG 2.2 and ADA to ensure that content is perceivable, operable, understandable, and robust. Accessibility involves thoughtful design decisions, like proper color contrast and clear structure, which improve usability for all visitors.

In practice, accessibility benefits a wide range of users, including those with visual, auditory, cognitive, or motor impairments, and contributes to a better overall experience. When accessibility principles are applied correctly, your website becomes easier to use across devices, browsers, and assistive technologies.

A website becomes inaccessible when its structure or design prevents users from completing actions or accessing information. Common barriers include missing alt text for images, poor color contrast, or interactive elements that cannot be accessed by keyboard. These issues can prevent users with disabilities from fully engaging with your content.

The Accessibility Scanner helps detect many of these problems automatically and offers remediation tips to help your team resolve them efficiently. By addressing such barriers early, you improve not only compliance readiness but also user satisfaction and trust.

After your scan completes, you’ll receive a detailed report that highlights accessibility issues categorized by severity. The report outlines specific technical recommendations and visual guidance to assist in the remediation process.

Teams can use this report as a roadmap for improvement, assigning tasks, setting priorities, and re-scanning to validate progress. This iterative process promotes ongoing improvement and transparency in accessibility practices.

Automated accessibility scanning identifies a broad range of detectable issues, such as missing labels, invalid ARIA roles, or contrast violations. These automated checks cover technical barriers that directly impact usability for people with disabilities.

However, some areas, such as visual readability or logical flow, still require human assessment. Combining automated testing with manual review ensures that both technical and contextual issues are addressed comprehensively.

Automated testing offers speed and consistency, identifying many of the most common technical issues across multiple pages in seconds. It provides quantifiable data for developers and design teams to act on quickly.

Manual audits, on the other hand, evaluate contextual aspects such as user flow, interactive clarity, and how assistive technologies interpret page elements. Used together, they provide a balanced and complete view of accessibility performance.

Accessible websites tend to perform better in search results because they rely on structured, semantic HTML, descriptive alt attributes, and meaningful link text. These practices align closely with SEO principles.

In addition to improving discoverability, accessibility optimization leads to a smoother, more intuitive user experience. That means visitors spend more time on your site, engage more deeply, and have fewer navigation challenges.

Most scans complete in under a minute for a single page, making it easy to integrate accessibility testing into your regular workflow. The system evaluates structure, contrast, form usability, and navigational flow quickly.

For larger websites, scan duration may vary depending on the number of pages and complexity of code. Regardless of size, you’ll receive actionable results without any disruption to website performance.

Start by using Clym’s free Accessibility Scanner to identify WCAG 2.2 and Section 508 issues automatically. These automated insights provide an excellent foundation for your accessibility strategy.

To complement that, conduct manual evaluations focusing on screen reader navigation, keyboard usability, and overall readability. This combination provides a full view of how real users interact with your website.

Clym’s Accessibility Scanner is a reliable starting point for automated accessibility checks. It integrates seamlessly with other Clym tools, such as the Accessibility Widget, Accessibility Statement, and Issue Reporting, creating a unified workflow for testing and improvement.

By combining these tools, organizations can move from detection to remediation, maintain documentation, and demonstrate ongoing efforts toward accessibility readiness.

Your scan results list each issue by type, severity, and location, with linked recommendations for remediation. Developers can correct code-level issues, while content teams address descriptions, headings, and visuals.

Once fixes are applied, running a follow-up scan confirms whether changes have improved accessibility scores and user experience. This continuous approach encourages iterative, measurable enhancement.

Clym’s Accessibility Scanner is free to use, allowing anyone to perform accessibility scans and download detailed reports at no cost. This helps businesses start their accessibility journey without initial investment barriers.

For organizations seeking more extensive support, additional Clym tools such as the Accessibility Widget and Accessibility Statement can assist with long-term monitoring, documentation, and transparency efforts.

The scanner tests against WCAG 2.2, Section 508, and EN 301 549 accessibility criteria, ensuring that results align with leading international frameworks. Each test assesses compliance at different success levels (A, AA, AAA) to identify where improvements are needed.

These standards are recognized globally and form the foundation for many accessibility regulations, making them critical for businesses operating across regions.

The accessibility score is calculated using quantifiable checks defined by WCAG 2.2 and Section 508 guidelines. Automated testing ensures repeatable, objective results for technical issues such as color contrast, keyboard traps, and label accuracy.

That said, while the score reflects measurable progress, it works best as part of a larger accessibility strategy that includes periodic manual reviews for qualitative insights.

Yes. You can add multiple URLs to assess how accessibility varies across your website. This allows for consistent tracking and identification of patterns that may recur on different pages or sections.

Multi-page scanning also provides insight into whether accessibility standards are uniformly applied across your entire website ecosystem, from landing pages to deeper user flows.

Yes. Reports can be exported as PDFs or shared securely online, making it easy for cross-functional teams to collaborate. Design, content, and development teams can each view findings relevant to their responsibilities.

Sharing accessibility reports helps build a culture of transparency and shared ownership, ensuring every team member contributes to continuous improvement.

No. The Accessibility Scanner runs external checks similar to a regular visitor session. It analyzes publicly available data only and does not modify or slow down your website.

This allows you to perform scans during active site hours without any disruption to users or impact on load times.

Only summarized results, such as detected issues and scores, are securely stored for future reference. Sensitive information, private content, and source code are never permanently saved.

This limited data storage approach balances transparency with privacy, providing traceability for accessibility progress without exposing proprietary information.

The Accessibility Scanner connects with Clym’s Accessibility Widget, Accessibility Statement, and Issue Reporting tools to form a cohesive ecosystem for accessibility management. These tools together support detection, reporting, and ongoing improvement.

This integrated workflow helps organizations maintain transparency, demonstrate due diligence, and provide users with clear communication channels for accessibility feedback.
