Try CoTester: Ditch Manual QA. Test, Debug, Execute in a Snap!
In 2025, accessibility is a core part of how businesses build digital products. Whether creating a corporate website, an internal enterprise system, or a mobile app, accessibility means ensuring everyone can use it, regardless of context or ability.
This inclusive mindset is grounded in global standards like WCAG 2.2, which guide how interfaces should behave across devices, browsers, and assistive technologies.
Legal frameworks, such as the ADA (Americans with Disabilities Act), US Section 508, and EN 301 549, further raise the bar for businesses operating in regulated industries or doing government-related work.
In summary, accessibility goes beyond ADA compliance tools; it helps create frictionless, trustworthy experiences. But that takes more than good intentions. You also need the right tools.
Accessibility testing tools help you find barriers early, catch patterns that exclude users, and fix issues before they ship. This blog covers the best ones to use in 2025. Check them out.
12 Accessibility Testing Tools in 2025
When integrated into your workflow, the following testing tools make accessibility more consistent, collaborative, and scalable—and ultimately, more human:
1. TestGrid
If you’re already using TestGrid for real device or cross-browser testing, then there’s a helpful addition you might not want to overlook: built-in accessibility testing.
This feature lets you directly evaluate your website’s compliance with WCAG standards within the TestGrid Real Device cloud.
You don’t need to switch tools or run separate audits. If you’re already inside a TestGrid browser session, you can run accessibility tests by clicking the “Accessibility Testing” button in the interface. It’s that simple.
TestGrid’s accessibility testing tool is built around WCAG 2.2 Level A and AA. It captures metrics for each page you test and maps them to WCAG guidelines, helping you identify where your website may fall short.
You can also organize results and group-related tests in your dashboard and reuse the exact session details if testing a complete user journey across multiple pages. Moreover, the test results are broken down page by page, with each report displaying issues by severity:
- A short description of each issue
- A help section with recommendations for fixing it
- A code-level HTML snippet to pinpoint where the issue occurs
- The WCAG guideline references so that you can understand the rule behind each finding
If you currently use TestGrid, you can run accessibility tests immediately. But if you don’t, start your free trial with TestGrid or book a demo to see what difference this feature can make in your accessibility testing endeavors.

What to Look for in Accessibility Testing Tools
You know how important accessibility is. You know all the best options in the market. The next step is to understand how to pick the most ideal accessibility testing tool. We’ve laid out all the critical factors to consider:
1. Comprehensive testing
Your choice of tool must cover a wide range of accessibility checks. This includes automated testing for code-level issues and support for manual techniques like color contrast analysis or keyboard-only navigation.
The more complete the coverage, the more confident you can be in your test results—and isn’t that your objective?
2. Standards compliance
Start with the basics. The whole point of running accessibility tests is to ensure your digital product is aligned with standards, like WCAG 2.1 and 2.2. Depending on where you operate, you must also account for regional regulations like Section 508 (US) or EN 301 549 (EU). Standards create a clear baseline for what should be tested and why.
3. Workflow integration
Accessibility testing works best when it fits into the rest of your process. Choose a tool that integrates well with your development and deployment stack.
Whether you’re using Jira, GitHub, or Azure DevOps, a solution that plugs into where your team already works will be easier to adopt and maintain.
4. Usability and reporting
The tool itself should be accessible.
If your team can’t produce clear reports, actionable recommendations, and well-explained errors, then there’s no point in using that accessibility testing tool. It’s essential to work with a solution that tells you exactly what’s wrong and how to fix it.
5. Real-device and cross-platform support
Pick a solution that works across browsers, device types, and operating systems. That includes mobile, desktop, and tablet environments.
If you’re building native apps or responsive interfaces, this becomes even more important. Real users rely on real devices. Your accessibility testing strategy should reflect that.
6. Localization and internationalization support
If your digital product serves a global audience, accessibility should extend beyond English-speaking users. Your accessibility testing software should test for localized content, such as right-to-left text, language attribute usage, localized alt text or labels, and non-Latin scripts.
Some WCAG tools also help evaluate your UI’s accessibility across cultural or linguistic contexts. This is essential for inclusive design at scale.
7. Security and privacy compliance
Web accessibility testing tools often analyze live apps, internal infrastructure, or sensitive user information, so security matters. Ensure the tool complies with relevant data protection standards like GDPR, SOC 2, or HIPAA, depending on your region and domain.
Many cloud-based WCAG tools offer clear data handling policies, encryption standards, and role-based access control (RBAC) to safeguard data during security testing.
8. Pricing and support
What does your budget look like? Some accessibility testing tools are open source. Others are part of larger platforms with licensing models. Consider what makes sense for your team’s size and testing requirements.
Secondly, if you invest money in a tool, you want to be able to receive appropriate support for it, too. Therefore, check if the selected tool has proper documentation, onboarding resources, and customer service options.
Build More Inclusive Experiences, Consistently and at Scale
If you’ve read this far, we’re hopeful you know how to approach the search for your accessibility testing tool. The key lies in finding one that fits your team’s workflow. For instance, some may need deep integration with CI pipelines and version control.
Others may benefit from visual dashboards or browser extensions easily shared across roles. Open-source WCAG tools offer flexibility, but commercial platforms like TestGrid offer more polish, support, and intuitiveness.
Whatever your choice, make accessibility part of your workflow, not an afterthought. Start small, test early, and build the habit. Good luck!
Frequently Asked Questions (FAQs)
1. Is accessibility testing only for developers?
No, it’s not. In fact, accessibility benefits from cross-functional input. Content writers can improve clarity, hierarchy, and screen reader context. Designers can focus on structure, contrast, and interaction patterns. Testers help catch edge cases and verify keyboard behavior. Accessibility testing delivers stronger results when everyone contributes.
2. How do AI-based accessibility testing tools work?
AI accessibility testing software solutions often simulate user behavior, like how a screen reader might navigate a landing page. They could also be trained on past accessibility violations to flag issues in dynamic content. More importantly, AI-driven accessibility testing tools are useful for testing large or frequently updated sites.
3. Can accessibility testing be fully automated in 2025?
Even though automation covers many common issues, such as misaligned heading structure, misuse of ARIA, poor color contrast, and missing alt text, not all accessibility issues can be measured by rules alone.
You still need to run tests using assistive technology and manually check the interaction flow. Combine automated testing with exploratory testing for superior results.
4. Can tools for accessibility testing help me avoid legal risk (e.g., ADA lawsuits)?
Although no tool guarantees 100% legal protection alone, an accessibility testing tool identifies issues early and provides a framework for remediation. Supplement that with manual checks, and you can integrate stronger compliance into your testing strategy. Remember: accessibility is a process, not a one-time fix.
