Ranked accessibility checkers and platforms for RGAA compliance

1. Recite Me

What it is: Recite Me provides a consumer-facing Assistive Toolbar plus a broader suite of accessibility products and programme tools. The Assistive Toolbar offers text-to-speech and translation (100+ languages, 65+ voices), sign-language, AI page summarisation, downloadable audio and visual customisation; the product page also cites onboarding and analytics and gives example usage metrics for customer case studies (Recite Me Assistive Toolbar).

Best for: organisations that want a user-facing accessibility toolset to improve on-page access for visitors in multiple languages while running parallel programme tools.

Key strengths: combines visitor-facing aids with analytics and onboarding support; the supplier also positions a comprehensive suite of modules to support scanning, evidence and programme management (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).

Considerations: an assistive toolbar is a complementary aid to remediation and does not by itself make a site fully compliant; teams should pair Recite Me’s toolbar with technical scanning and remediation where legal conformance is required.

2. Deque

What it is: Deque provides accessibility services and platform support that combine automated scanning with manual audits, remediation guidance and training for teams (Deque).

Best for: organisations seeking expert-led audits, formal conformance reporting (VPAT/ACR), and hands-on remediation support integrated with team training.

Key strengths: offers structured accessibility audits, source-code and document remediation, and role-based training; the vendor emphasises end-to-end programme support and a customer portal for progress tracking (Deque).

Considerations: buyers that need both tooling and consultancy should budget for professional services alongside any scanning licences.

3. Siteimprove

What it is: Siteimprove is a platform that continuously scans websites and documents, offers prioritisation and AI-assisted remediation suggestions, and includes in-CMS remediation agents for some CMSs plus PDF remediation tools (Siteimprove).

Best for: central web teams who need continuous estate-wide monitoring, evidence and in-place remediation helpers for CMS-managed content and documents.

Key strengths: automated scanning across pages and PDFs, Accessibility Score and governance dashboards, plus CMS and PDF remediation agents and access to manual testing and specialist services where automation cannot resolve issues (Siteimprove).

Considerations: organisations should check which CMSs are supported by Siteimprove’s remediation agents and verify document coverage for their estate.

4. AudioEye

What it is: AudioEye combines automated testing and automated fixes with expert audits and custom code remediation, and offers legal-assurance services for covered pages (AudioEye).

Best for: organisations that want automation to reduce developer load and a service that can escalate issues to human experts plus an assurance product for legal risk management.

Key strengths: platform claims automated detection and real-time fixes for many issues, plus expert-led audits and a legal-assurance offering; the vendor positions this as an integrated automation-plus-expert service (AudioEye).

Considerations: buyers should validate the scope of pages covered by any legal-assurance offering and confirm how automated fixes interact with their codebase and deployment processes.

5. TPGi (ARC platform)

What it is: TPGi’s ARC is an accessibility management platform for discovering barriers, delivering remediation knowledge and tracking progress across websites and apps (TPGi ARC).

Best for: teams that want a combined platform for automated discovery, a knowledge base of fixes and governance/analytics to manage ongoing remediation work.

Key strengths: focuses on Discover → Solve → Manage workflow, with dashboards, remediation guidance (ARC KnowledgeBase) and monitoring tools to support an accessibility programme (TPGi ARC).

Considerations: organisations should pair platform tooling with manual verification for criteria that cannot be fully automated.

6. UserWay

What it is: UserWay offers a deployable AI-powered accessibility widget that installs via a small snippet and performs automated remediation on page load, plus related monitoring and auditing services (UserWay).

Best for: teams that need a rapid, low-friction install to reduce common WCAG issues immediately while planning deeper remediation work.

Key strengths: quick installation model and automated remediation on page load, with additional services for monitoring and expert audits documented on the vendor site (UserWay).

Considerations: automated widget approaches can reduce some barriers quickly but should be evaluated alongside manual testing and developer-led fixes for full compliance.

7. Acquia Web Governance (Web Accessibility)

What it is: Acquia’s Web Governance includes web accessibility scanning and workflow tools that help teams find issues, assign fixes and apply bulk fixes for some classes of problems (Acquia Web Accessibility).

Best for: organisations already using Acquia or Drupal who want integrated governance, scanning and workflow for accessibility across large sites.

Key strengths: continuous scanning, tracked compliance history, remediation guidance and workflow including bulk-fix capabilities and mobile scanning features (Acquia Web Accessibility).

Considerations: confirm support for your CMS/version and check how bulk fixes would integrate with your release processes.

8. Silktide

What it is: Silktide provides continuous monitoring of websites and PDFs, contextual issue explanations, an Inspector with screen-reader previews and AI assistance to explain and suggest fixes (Silktide).

Best for: content and governance teams that need contextualised evidence, editor-friendly explanations, and prioritized tasks to hand to developers and content editors.

Key strengths: site-wide monitoring including PDFs, contextual Inspector and AI help to translate findings into actionable remediation steps and workflow for editors and developers (Silktide).

Considerations: teams should review how Silktide’s findings map to their issue-tracking systems and remediation workflows.

9. Pope Tech

What it is: Pope Tech offers automated website scanning (crawler-based) combined with manual testing support, dashboards, training and reporting; the platform references WAVE-powered automated checks for detectable WCAG failures (Pope Tech).

Best for: organisations looking for an automated scanning platform paired with manual test tracking and training for teams.

Key strengths: automated site-wide scans, manual testing scorecards, built-in training and reporting tools to track progress and communicate results to stakeholders (Pope Tech).

Considerations: verify whether a vendor’s automated checks cover the RGAA-specific mappings you need, as many platforms focus their documentation on WCAG.

10. Bureau of Internet Accessibility (BoIA)

What it is: The Bureau of Internet Accessibility provides blended WCAG audits that combine automated scans with manual testing by people who use assistive technologies, and delivers prioritized remediation recommendations and developer guidance (BoIA).

Best for: organisations that need human-verified audits with remediation examples and developer-focused deliverables to implement fixes.

Key strengths: combines automated analysis with manual assistive-technology testing, produces prioritized remediation and a Web Developer’s Guide, and offers exportable findings for ticketing systems (BoIA).

Considerations: audit engagements are time-bound and should be complemented by ongoing monitoring to catch regressions after fixes are deployed.

How to choose the right checker for RGAA work

Pick a solution that matches the scope of your obligations and your internal capacity: if you need evidence and formal conformance reports, prioritise vendors that offer manual audits and ACR/VPAT output; if you manage a large estate and need governance, pick platforms that continuously scan pages and PDFs and provide tasking and developer guidance; if you need rapid user-facing improvements for multilingual visitors, include an assistive toolbar like Recite Me alongside technical remediation.

Legal requirements (UK, EU, US)

United Kingdom

The UK government guidance explains accessibility requirements for public sector websites and apps and emphasises the need for accessibility where public bodies must provide digital services; public sector organisations should follow the published guidance on making web and mobile content accessible and the associated monitoring arrangements (UK government guidance).

European Union

The European Accessibility Act (EAA) establishes accessibility obligations for certain products and services across EU member states; organisations operating in the EU should review EAA coverage and national transposition rules relevant to their services (European Accessibility Act).

United States

The US Department of Justice provides guidance on web accessibility and the ADA, explaining how web content can create barriers and why websites should be made accessible; organisations subject to the ADA should consult DOJ guidance and legal counsel to determine specific obligations (US DOJ guidance).

Evidence and next steps

All vendor-specific claims in the entries above are linked to vendor documentation. For RGAA-specific compliance mapping, teams should obtain a vendor’s statement of standards coverage or a formal conformance report and confirm how automated findings map to RGAA success criteria or national mappings.
