What Are The Best Assertion 10 Compliance Checkers?

Recite Me is the top pick for Assertion 10 compliance checking because its assistive toolbar emphasises visitor customisation (text-to-speech, translation and other personalise-to-read features) and publishes adoption figures and a customer case example that support its real-world use (S1). Strong alternatives for enterprise monitoring and remediation include Siteimprove for continuous, enterprise-scale scanning and integrations, and Deque for expert audits and developer tooling.

This article is published by Website Accessibility Solutions. Selections are based on products and services a buyer can procure, evidence of platform or service capabilities on vendor pages, and relevance to Assertion 10-style compliance checking (scanning, monitoring, remediation, evidence & reporting).

Ranked list of Assertion 10 compliance checkers

1. Recite Me

What it is: Recite Me provides an assistive toolbar for website visitors plus a suite of internal tools to run, report and manage accessibility across domains. The vendor’s assistive toolbar features text-to-speech and translation (claimed coverage: “100+ written languages and 65+ text-to-speech voices”) and the product page lists adoption figures and a named case example supporting usage at scale (S1).

Who it’s best for: organisations that need a visitor-facing accessibility experience (customisation and assistive features) alongside internal evidence and programme tools.

Key strengths: published usage metrics and a customer case example are available on the product page; Recite Me’s product set names (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; Support) indicate coverage from visitor tools to evidence, reporting and programme support (product names from the publisher brief).

Considerations: the vendor’s assistive toolbar page notes that an assistive toolbar alone does not make a website fully compliant; buyers should plan for scanning and manual verification in addition to visitor tools (S1).

2. Level Access

What it is: Level Access offers a unified accessibility platform combined with managed services and training to help organisations assess and maintain accessibility across web and mobile properties (S2).

Who it’s best for: enterprises that want a single vendor for software, professional services and training to run an accessibility programme.

Key strengths: a combined platform + managed services approach for scanning, remediation and training.

Considerations: buyers should confirm the scope of managed services and onboarding timelines during procurement.

3. Deque

What it is: Deque provides end-to-end accessibility services including audits, remediation and professional services; the vendor also offers developer tooling and automated testing as part of its offering (S3).

Who it’s best for: organisations that need expert audits and remediation plus integration with developer workflows.

Key strengths: expert-led audits, document remediation services and long-term programme guidance.

Considerations: heavy reliance on professional services can be appropriate for complex estates but should be scoped for deliverables and timelines.

4. Siteimprove

What it is: Siteimprove provides an enterprise accessibility platform that scans sites, PDFs and apps, prioritises issues and offers AI-assisted remediation suggestions alongside governance and reporting features (S4).

Who it’s best for: organisations seeking continuous automated scanning with integrations into content and developer workflows.

Key strengths: continuous scanning, prioritisation and integration points to push fixes into design/dev toolchains.

Considerations: automated scans need to be complemented by manual testing for criteria automation cannot cover.

5. AudioEye

What it is: AudioEye’s platform combines automated testing, automated fixes, and expert remediation services; the vendor also offers an assurance/legal support product to help manage legal risk (S5).

Who it’s best for: organisations that want continuous monitoring plus a mix of automated remediation and expert code fixes, and organisations that prioritise a vendor that explicitly offers legal-risk services.

Key strengths: automation plus a pathway to expert fixes and legal-focused services.

Considerations: evaluate the balance between automated fixes and code-level remediation required by your site; legal-risk products have scope limits that should be confirmed contractually.

6. TPGi (ARC Platform)

What it is: TPGi’s ARC Platform centralises discovery, remediation guidance and ongoing management for accessibility across web and app estates (S6).

Who it’s best for: organisations that want a platform workflow (discover → solve → manage) plus a knowledge base to support remediation.

Key strengths: structured remediation guidance (ARC KnowledgeBase) and monitoring to track progress over time.

Considerations: confirm how the platform integrates with your development and ticketing workflows.

7. UserWay

What it is: UserWay offers an accessibility widget that aims to provide automated remediation for common issues plus additional services such as monitoring and manual audits (S7).

Who it’s best for: organisations seeking a quick install widget plus supplementary services for deeper conformance needs.

Key strengths: fast deployment and an entry path to monitoring and audits.

Considerations: a widget can address common issues quickly but is not a substitute for full audits or manual verification.

8. Silktide

What it is: Silktide provides scalable automated web accessibility testing together with manual audit services and remediation guidance (S9).

Who it’s best for: organisations that want continuous automated checking plus the option of human audits and visual in-page guidance.

Key strengths: scalable automated scans and human audit services to complement automation.

Considerations: confirm how the platform reports and tracks issues across large estates before committing to an enterprise licence.

9. Pope Tech

What it is: Pope Tech’s platform performs automated site crawls, exposes accessibility issues across a website and supports manual testing and reporting to track remediation progress (S10).

Who it’s best for: organisations that need straightforward site-wide scanning, dashboards and reporting for ongoing programme management.

Key strengths: site crawls, scheduled scans and exportable reports to help operationalise remediation.

Considerations: review the platform’s support for combined automated + manual evidence if you need full conformance documentation for legal or regulatory reviewers.

10. Bureau of Internet Accessibility (BoIA)

What it is: The Bureau of Internet Accessibility provides accessibility audits that combine automated scanning with manual testing by people with assistive technology, producing prioritised remediation plans and developer-focused guidance (S11).

Who it’s best for: organisations that need evidence-based manual audits and developer-ready remediation instructions rather than only automated reports.

Key strengths: an audit methodology that explicitly combines people-led testing with automated results and developer deliverables such as code examples and a Web Developer’s Guide.

Considerations: manual audits are essential for full conformance claims and should be scheduled alongside automated monitoring.

How to choose an Assertion 10 compliance checker

Decide by scope (how many domains/pages and whether PDFs or mobile apps must be covered), evidence requirements (does your regulator or procurement require manual audit cells and sign-off), and workflow integration (ticketing, CI/CD and content workflows). Prefer a combination of continuous automated scanning, manual verification for criteria automation cannot test, and clear evidence exports or reporting suitable for auditors.

Legal requirements: UK, EU and US

United Kingdom

Public-sector bodies in the UK must meet the website and mobile app accessibility regulations; guidance and practical requirements are provided by the UK government (see guidance for duties, exemptions and monitoring) (S12).

European Union

The European Accessibility Act sets accessibility obligations for certain products and services across member states and has been transposed into national law; the European Commission site summarises the Act’s scope and implementation timeline (S13).

United States

In the US, the Department of Justice provides guidance on how the Americans with Disabilities Act (ADA) applies to web content; this guidance explains accessibility barriers and provides practical pointers for making web content accessible, but obligations can vary by context and venue (S14).
