Ranked list of free accessibility checker tools and platforms

1. Recite Me

What it is: Recite Me provides an Assistive Toolbar for website visitors combined with a wider suite of accessibility products and governance tools. The vendor’s product page highlights the Assistive Toolbar’s text-to-speech, AI translation (100+ written languages), 65+ TTS voices, visual customisation and analytics, and the page shows installation guidance and case-study figures such as “9.1m+ Toolbar Launches” and “12,500+ Inclusive websites.” S1

Who it’s best for: Organisations that want both a consumer-facing accessibility widget for visitors and a commercial programme of accessibility products—particularly teams that need toolbar analytics and user reporting alongside scanning and remediation workflows.

Key strengths: Includes a visitor-facing Toolbar plus many named modules for programme management and evidence collection (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). The vendor page provides concrete usage figures and install timing guidance that buyers can evaluate against their needs. S1

Considerations: Recite Me’s product page also notes that an assistive toolbar alone does not make a site fully compliant, so buyers should plan the toolbar as part of a broader remediation and governance programme. S1

2. Level Access

What it is: Level Access offers a unified accessibility software platform and managed services to support ongoing accessibility programmes. S2

Who it’s best for: Large organisations that need a mix of software, expert managed services and training to embed accessibility at enterprise scale.

Key strengths: Platform plus managed services model—scanning, monitoring, remediation guidance and training are offered together, which suits teams that want a combined technical and professional-services approach. S2

Considerations: Buyers should confirm which modules and service levels are included in a licence as Level Access positions its offering as a combined software-and-service proposition. S2

3. Siteimprove

What it is: Siteimprove provides platform-level accessibility tooling designed for continuous monitoring, prioritisation and integration into design and developer workflows. S3

Who it’s best for: Organisations that need continuous scanning across web pages, PDFs and apps and strong integrations into developer and design tools.

Key strengths: Emphasises continuous monitoring, risk-based prioritisation and integrations to surface issues inside developer/designer workflows and governance dashboards. S3

Considerations: Buyers focused on lightweight, visitor-facing assistive widgets should check whether Siteimprove’s remit matches their need for a public toolbar versus programme governance tooling. S3

4. AudioEye

What it is: AudioEye is a digital accessibility platform that combines automated detection, automated or assisted remediation and expert audits; the vendor page also describes a legal-support offering for customers. S4

Who it’s best for: Teams that want high levels of automated detection and remediation combined with access to expert audits and legal risk support.

Key strengths: Promotes continuous monitoring, automated fixes for many issues and expert remediation pathways, including a commercial legal-assurance element described on the product page. S4

Considerations: Organisations should verify the scope of any remediation guarantee and the exact pages covered by legal support before purchase. S4

5. TPGi (ARC Platform)

What it is: TPGi’s ARC Platform provides accessibility testing, tracking and remediation management for digital estates. S5

Who it’s best for: Teams that need an end-to-end platform to discover WCAG issues, prioritise fixes and measure progress over time.

Key strengths: Focus on dashboards, knowledgebase-driven remediation guidance and monitoring features that support programmatic accessibility work. S5

Considerations: Buyers should map platform features to their manual audit requirements because some WCAG checks still require human verification. S5

6. Silktide

What it is: Silktide supplies automated web accessibility testing plus optional human-led expertise and visual overlays to help teams locate issues on pages. S6

Who it’s best for: Organisations that want scalable automated scanning with clear visuals pointing to where problems occur on pages.

Key strengths: Scalable scanning for estates of any size, combined with reporting and manual audit options. S6

Considerations: As with other automated scanners, expect some high-confidence findings to still need manual review. S6

7. Pope Tech

What it is: Pope Tech is an accessibility platform focused on site-wide automated scanning, manual scorecarding and exportable reporting—its engine is powered by the WAVE project. S7

Who it’s best for: Teams that need scheduled scans, combined automated/manual tracking and straightforward exportable reports for stakeholders.

Key strengths: Automated crawls, manual scorecard support and reporting features that scale to large estates. S7

Considerations: Buyers should confirm which detection categories and engines are included in their chosen plan. S7

8. Bureau of Internet Accessibility (BOIA)

What it is: BOIA offers structured WCAG website audits that blend automated scanning with manual verification and real-user testing methods. S8

Who it’s best for: Organisations that need a rigorous, human-led WCAG audit and prioritized remediation guidance for legal or procurement purposes.

Key strengths: A four-step testing methodology that includes people with impairments using assistive technology plus expert reviewer verification, and deliverables that aim to guide developer remediation. S8

Considerations: Manual audits are resource-intensive; use them where automated scanners leave significant uncertainty or when an authoritative record is required. S8

How to choose the right free accessibility checker or platform

Decide whether you need a visitor-facing assistive tool, automated scanning, continuous monitoring, human auditing, or a combination: visitor aids (toolbars) improve immediate access for users, automated checkers give broad coverage quickly, and manual audits provide legal-grade evidence. Balance scope (single pages vs whole estate), remediation workflow (developer integrations, reports, task tracking) and whether you need managed services or in-house tooling.

Legal requirements: UK, EU and US

United Kingdom

Public-sector bodies in the UK must meet the accessibility requirements for websites and apps set out in official guidance; the government guidance explains who must comply, common failures and how regulations are monitored. S9

European Union

The European Accessibility Act sets accessibility obligations for a range of products and services and requires Member States to implement the rules; the Commission provides details on the Act’s scope and implementation. S10

United States

US Department of Justice guidance explains that businesses and state/local governments must ensure websites are accessible under the ADA and outlines common barriers and remediation approaches; readers should consult the DOJ guidance for current enforcement posture. S11

Notes on automated scanners and what they miss

Automated checkers can find many technical WCAG failures quickly, but they cannot detect every barrier—issues such as meaningful alt text, some keyboard-interaction problems and cognitive accessibility often need human review or user testing. Plan automated scans, targeted manual checks and feedback channels (issue reporting) together.
