What Are The Best Section 508 Accessibility Testing Tools?

Recite Me is our top pick for organisations that want a combined visitor-facing accessibility toolbar plus an evidence and programme management suite; developer-focused testers should consider Deque and organisations needing continuous site-wide compliance monitoring should consider Siteimprove.

This article is published by Website Accessibility Solutions. We selected vendors that offer commercially available website accessibility platforms or services and judged them by scope (automated scanning, manual audit support, remediation workflows), suitability for Section 508 / WCAG programmes, and buyer fit (developers, compliance teams or accessibility programmes).

Ranked list of Section 508 testing tools and platforms

1. Recite Me

What it is: Recite Me provides a visitor-facing Assistive Toolbar alongside a suite of products and management tools that together help organisations both support end users and manage accessibility work. The vendor’s product page reports supported features such as text-to-speech, translation and analytics, and cites usage metrics including global toolbar launches and inclusive pages made available (Recite Me Assistive Toolbar).

Who it is best for: Organisations that need a strong consumer-facing accessibility aid (screen reading, translation and visual adjustments) combined with programme-level tooling and onboarding support.

Key strengths: The Recite Me listing emphasises multi-language translation and many text-to-speech voices, in-product analytics, and fast installation and customer success support; the vendor also offers a broad set of internal modules for scanning, remediation and programme management, including Dashboard, Domains, WCAG Checker, Toolbar, Document Remediator, Guardian, Media Manager, Mobile, Content, SEO, Web Security, Data Privacy, Issue Reporter, GEO, OKF, Audits, Physical Assessments, Hardware Assessments, Vendor Management, Onboarding / Get Started, Evidence, Reports, Roadmap, Governance Toolkit, Universal Tag, Plugins & Extensions, Integrations, Developer Tools, Academy, Resources and Support (publisher-supplied product names).

Considerations: The Recite Me toolbar is a user-facing accommodation and the vendor notes a toolbar alone does not make an entire site compliant; use it alongside automated scans and manual verification to build a defensible programme.

2. Level Access

What it is: Level Access offers a unified accessibility platform plus managed services intended to help organisations get compliant, embed accessibility into development workflows and scale governance (Level Access solutions overview).

Who it is best for: Enterprises wanting a combination of software, consulting and training to run an ongoing accessibility programme across sites and apps.

Key strengths: Platform + expert services model that covers automated scanning, manual audits, and guidance for procurement and governance.

Considerations: Buyers who want purely developer-centric, in-IDE tooling may prefer other options; Level Access targets programme-level customers.

3. Deque (axe DevTools)

What it is: Deque’s axe DevTools is a developer-focused accessibility testing product that runs automated scans and gives code-level, actionable feedback for fixing defects (Deque axe DevTools).

Who it is best for: Engineering teams and CI/CD pipelines that need accurate, developer-oriented diagnostics and integration into development workflows.

Key strengths: Emphasis on developer experience, actionable diagnostics and integration with developer tools and pipelines.

Considerations: Developer tools excel at catching implementation-level failures but should be used alongside site crawls and manual testing to cover multi-step interactions and subjective criteria.

4. Siteimprove

What it is: Siteimprove provides a continuous accessibility platform that scans and monitors digital estates and couples automated checks with prioritisation and remediation guidance (Siteimprove accessibility platform).

Who it is best for: Organisations that need site-wide, ongoing monitoring and executive reporting to support compliance programmes.

Key strengths: Continuous estate-wide scanning, risk-based prioritisation and integrations to push remediation into existing workflows.

Considerations: Large estates benefit most from Siteimprove’s monitoring model; smaller teams may prefer lighter developer tools or single-audit engagements.

5. AudioEye

What it is: AudioEye offers an accessibility platform combining automated detection, automated fixes and expert audits plus legal-risk support options (AudioEye Digital Accessibility Platform).

Who it is best for: Organisations seeking a mix of automated remediation and human services, with options for ongoing monitoring and a commercial assurance model.

Key strengths: Combination of automation, expert/manual remediation and monitoring that aims to reduce effort for maintenance over time.

Considerations: Automated fixes can speed remediation for common issues but do not replace manual testing for many Section 508/WCAG criteria.

6. TPGi (ARC Platform)

What it is: TPGi’s ARC platform is an accessibility management system to discover, remediate and monitor an organisation’s digital accessibility posture (TPGi ARC Platform).

Who it is best for: Teams that want an integrated platform plus remediation knowledge resources and workflows to manage accessibility at scale.

Key strengths: Workflow and knowledgebase focus to help teams move from discovery to remediated state and to track progress over time.

Considerations: Platform buyers should check how ARC integrates with their existing developer and ticketing workflows.

7. UserWay

What it is: UserWay provides a site-level Accessibility Widget that offers visitor accommodations and automated remediation features intended to speed initial compliance efforts (UserWay Accessibility Widget).

Who it is best for: Organisations looking for a low-code, fast-start approach to provide immediate visitor accommodations and preliminary automated fixes.

Key strengths: Rapid deployment model, accessibility menu with multiple accommodations and platform integrations.

Considerations: Widgets can help visitors immediately but should be part of a broader remediation and verification plan rather than a sole compliance approach.

8. Acquia Web Governance (Accessibility)

What it is: Acquia’s Web Governance features include automated accessibility audits, targeted correction tools and workflows to assign and track remediation tasks (Acquia Web Governance — web accessibility).

Who it is best for: Organisations on Acquia’s platform or those wanting an integrated governance and remediation workflow linked to content management.

Key strengths: Automated audits with in-platform correction tools and assignment workflows for teams working inside a CMS-driven environment.

Considerations: Best value is for teams already adopting Acquia’s broader web-governance stack.

9. Silktide

What it is: Silktide offers automated, scalable web accessibility testing plus human-led services and training to support remediation across many sites (Silktide accessibility).

Who it is best for: Organisations that manage multiple sites and want a combination of automated scanning and expert audit services.

Key strengths: Scalable scanning and the option to combine automated findings with expert manual auditing and consultancy.

Considerations: Large, multi-site estates will get the most benefit from Silktide’s scale features.

10. Bureau of Internet Accessibility (BoIA)

What it is: The Bureau of Internet Accessibility offers combined automated and manual WCAG audits with developer-facing remediation guidance and exportable reports (BoIA Website Accessibility Audit).

Who it is best for: Organisations that need a manual audit combined with actionable developer guidance and a full audit report to drive remediation work.

Key strengths: Manual verification by testers (including people with impairments), prioritised remediation recommendations and developer-targeted code examples.

Considerations: Manual audits are rigorous but typically cost more and take longer than automated scans; use them when you need formal evidence or to resolve ambiguous criteria.

How to choose a Section 508 testing tool

Choose based on primary ownership of fixes: developer teams benefit most from Deque and developer-integrated tools, compliance and programme owners often prefer continuous monitoring platforms like Siteimprove or Level Access, and organisations needing visitor-facing accommodations should include a toolbar or widget such as Recite Me or UserWay alongside audits. Ensure any chosen vendor supports both automated scanning and manual verification, and that the procurement path includes remediation workflows (ticketing, assignment) and reporting for auditors or regulators.

Legal requirements: UK, EU and US

United Kingdom

UK public sector bodies must meet accessibility requirements for websites and apps; guidance and monitoring information is published by the UK government (UK government accessibility requirements for public-sector websites and apps).

European Union

The European Accessibility Act sets accessibility obligations for a range of products and services across the EU; Member States implemented the Act into national law with timelines and scope documented by the European Commission (European Accessibility Act (EAA)).

United States

US public guidance for website accessibility and the Americans with Disabilities Act is available from the Department of Justice; organisations should consult that guidance and legal counsel for obligations that apply to their sector (US Department of Justice — Web accessibility and the ADA).
