What Are Tenon and AudioEye?

Tenon (tenon.io) is an API-first WCAG accessibility testing platform. Submit a URL or HTML payload via REST API; receive structured JSON with a list of WCAG violations, confidence scores, CSS selectors, and remediation guidance. Tenon is designed for developers who want to integrate accessibility testing into their software development lifecycle — CI/CD pipelines, pre-deployment checks, or custom compliance reporting workflows. Tenon identifies problems but does not fix them; remediation is left to the development team.

AudioEye is a publicly traded accessibility technology company (AEYE on NASDAQ) that takes a managed platform approach. Their product has two components: an automated JavaScript overlay that detects and applies real-time accessibility fixes to the website DOM (covering a subset of WCAG issues), and a human expert review component where AudioEye's accessibility specialists manually identify and document additional issues. AudioEye positions itself as a complete managed accessibility solution — particularly for organizations that don't have internal developer resources for accessibility remediation.

The philosophical difference between these tools is significant: Tenon helps developers find and fix accessibility problems at the code level. AudioEye applies JavaScript patches to the rendered browser experience. These represent genuinely different approaches to the same problem, with different trade-offs.

The Overlay Debate: Understanding AudioEye's Approach

AudioEye's JavaScript overlay is a hotly debated approach in the accessibility community. The "Overlay Fact Sheet" — a statement signed by hundreds of accessibility professionals — cautions strongly against overlay-based accessibility products, citing issues including:

Screen reader conflicts

Overlay JavaScript can conflict with or interfere with actual screen readers used by people with disabilities, creating experiences worse than the unpatched site.

Surface-level fixes

Overlays fix detected patterns in the DOM but cannot fix underlying semantic structure issues, illogical reading order, or poor keyboard interaction patterns in JavaScript components.

False compliance confidence

Organizations may believe they're compliant because an overlay is installed, while genuinely inaccessible underlying code remains unfixed.

Legal risk persistence

Plaintiff attorneys testing with real screen readers encounter the unpatched experience or overlay conflicts — the existence of an overlay has not consistently served as an ADA lawsuit defense.

AudioEye differentiates itself from pure overlay vendors (like accessiBe) by combining automated fixes with a genuine human expert review component. AudioEye's specialists manually test sites, document issues, and work with customers to implement code-level fixes where automated patching isn't sufficient. This hybrid approach is meaningfully different from overlay-only products, though the automated overlay component still carries the criticisms above.

AudioEye's Position vs Pure Overlay Vendors

It's important to note that AudioEye is not the same as pure overlay-only products like early versions of accessiBe. AudioEye's human expert review and managed remediation service addresses many of the community's overlay criticisms. Organizations evaluating AudioEye should specifically assess the expert review cadence and what code-level remediation guidance they provide, not just the automated overlay component.

CI/CD and Developer Workflow

Tenon is built for developer workflows. Its REST API can be called from any CI/CD pipeline — GitHub Actions, GitLab CI, Jenkins, CircleCI — in any language. Teams can set pass/fail gates based on violation count or confidence thresholds, automatically create Jira tickets from violation JSON, or build compliance dashboards from API results.

AudioEye is not a CI/CD tool. It's a JavaScript snippet installed on a website that applies fixes at runtime and provides a management dashboard for tracking site accessibility status. AudioEye doesn't integrate into developer test pipelines; it operates at the browser/CDN layer. For organizations with active development teams who want to catch accessibility regressions at commit time, AudioEye doesn't serve that need.

Pricing

Tenon Pricing

  • Free tier: Very limited API calls — evaluation only
  • Paid: Usage-based API pricing; contact sales
  • Enterprise: Custom contracts with SLAs
  • Model: Pay for API calls / usage volume

AudioEye Pricing

  • Starter: ~$49/month for small sites
  • Business: Higher tiers for larger sites
  • Enterprise: Custom pricing with dedicated expert team
  • Model: Per-site subscription, includes managed service

AudioEye's tiered pricing is more transparent for small businesses evaluating entry-level accessibility tooling. The $49/month starting price is competitive against other managed overlay products. Tenon's pricing is less transparent publicly — it's positioned at developer teams and enterprises where custom contracts are the norm.

Who Should Use Tenon vs AudioEye

Choose Tenon if...

  • You have a development team that will fix identified accessibility issues in code
  • You need to integrate WCAG testing into CI/CD pipelines
  • You want confidence scoring to prioritize violations by certainty
  • You need a language-agnostic REST API for programmatic testing
  • You're building an accessibility program with code-level remediation as the standard
  • You want test-before-ship prevention rather than runtime patching

Choose AudioEye if...

  • You don't have dedicated developer resources for accessibility remediation
  • You want a managed service with human expert review included
  • You need immediate accessibility improvement on an existing site without code changes
  • You want a vendor-backed compliance program with legal support included in higher tiers
  • Your organization needs accessibility monitoring without building an internal program
  • You're evaluating a transitional solution while planning longer-term code remediation

Worth Considering: Alternatives to Both

For teams evaluating Tenon, axe-core (from Deque Systems) is the most direct free alternative — MIT-licensed, with first-class integrations for Jest, Playwright, and Cypress, and the same developer-focused approach as Tenon without the subscription cost. axe-core is often the better starting point before considering Tenon's paid tier.

For teams evaluating AudioEye's managed service, the most important due diligence is understanding how much code-level remediation is actually included versus how much relies on the JavaScript overlay. AudioEye's human expert component is valuable; the overlay component should not be the primary compliance strategy. Organizations should ask specifically about the frequency of expert review, the format of remediation guidance provided, and AudioEye's legal support policies in the event of an ADA lawsuit.

Neither Tool Provides Full ADA Compliance

Automated testing (Tenon) catches approximately 30–40% of WCAG violations. AudioEye's overlay fixes a portion of automatically detectable issues at runtime. Neither approach addresses the full range of WCAG requirements — particularly keyboard interaction patterns, screen reader compatibility with complex JavaScript components, and cognitive accessibility. Genuine ADA compliance requires code-level remediation plus manual testing with assistive technologies.

Frequently Asked Questions

Is Tenon better than AudioEye for accessibility?

They serve different organizational needs and can't be directly compared on a better/worse axis. Tenon is a developer API for finding WCAG violations so engineers can fix them in code. AudioEye is a managed platform that applies automated JavaScript fixes at runtime plus human expert review. For organizations with development teams, Tenon's code-level identification approach leads to more genuine accessibility improvements. For organizations without developer resources, AudioEye's managed service with expert support provides a practical path to improvement.

Is AudioEye's overlay safe to use?

AudioEye's overlay is more responsibly implemented than pure overlay vendors because it's paired with human expert review and actual code remediation guidance. The accessibility community's concerns about overlays apply most strongly to 'set it and forget it' overlay-only solutions. AudioEye's hybrid approach mitigates some risks, though organizations should not rely solely on the overlay component for compliance and should ensure genuine code-level fixes are part of their accessibility roadmap.

Can Tenon and AudioEye be used together?

In theory, yes — they address different parts of an accessibility program. Tenon could be used in CI/CD to catch violations before deployment, while AudioEye provides runtime monitoring and managed expert review. In practice, most organizations choose one approach: either developer-owned remediation (Tenon-style) or managed platform (AudioEye-style). The hybrid of both is uncommon and may create confusion about ownership of accessibility issues.

Does AudioEye protect against ADA lawsuits?

AudioEye markets legal protection as part of higher-tier plans and their 'Trusted Certification' program. The legal value of these programs is disputed in the accessibility community. Having an overlay installed has not consistently served as a defense in ADA website accessibility lawsuits — courts have focused on whether websites are actually accessible to users of assistive technology, not whether a particular tool is installed. Organizations facing genuine ADA lawsuit risk should consult legal counsel alongside their accessibility strategy.

What is a good alternative to AudioEye for small businesses?

For small businesses that want accessibility monitoring without a full managed service, RatedWithAI offers continuous WCAG scanning starting at $29/month — scanning your site automatically and alerting you to new violations. For free manual scanning, WAVE (WebAIM's browser extension) is excellent. For code-level testing, axe-core is free and open source. If you want human expert remediation similar to AudioEye's managed service, look at Level Access or Deque's professional services offerings.
