Tenon.io and RatedWithAI both test websites for WCAG accessibility violations — but they're built for entirely different users. Tenon.io is a REST API that requires a developer to write code, parse JSON responses, and build custom reporting. RatedWithAI is a business compliance dashboard that requires no technical knowledge. The right choice depends entirely on who in your organization needs to act on accessibility data.
What Is Tenon.io?
Tenon.io is an API-first web accessibility testing service founded in 2013. It provides a REST API that developers call to run WCAG 2.1 accessibility checks against URLs or raw HTML. The API returns structured JSON results listing violations, their severity, CSS selectors, and suggested fixes. Tenon is designed to slot into automated test suites, CI/CD pipelines, and developer tooling — it's a programmatic testing backend, not a standalone compliance dashboard.
Key distinction: Tenon.io requires a developer to write API integration code. It has no native dashboard for non-technical users, no built-in monitoring scheduler, and no compliance history reports designed for business use. It's infrastructure for developer teams building accessibility into their workflow — not a tool for a business owner who wants to protect against ADA lawsuits.
Who Each Product Is Built For
Tenon.io
For: Development teams, QA engineers
API-first accessibility testing built for developers who want to integrate WCAG checks into CI/CD pipelines, automated test suites, and build processes. Raw JSON output. Code required.
RatedWithAI
For: SMB owners, compliance managers
Continuous ADA compliance monitoring built for non-technical business owners. Dashboard, compliance reports, and ADA lawsuit risk documentation — no coding, no API integration, $29/month.
Tenon.io Pricing vs RatedWithAI Pricing
Tenon.io uses API call-based pricing — plans are structured around the number of API requests per month. This model makes sense for development teams running automated tests in CI pipelines where call volume scales with deployments. It's confusing and impractical for a business owner who just wants their site monitored continuously at a predictable cost.
Tenon.io Pricing
- Free tier: Limited API calls/month, testing only
- Paid plans: Priced by API call volume per month
- Enterprise: Custom pricing for high-volume API usage
- Requires: Developer integration to use at all
- Dashboard: Tenon Studio available but designed for dev teams
RatedWithAI Pricing
- Free scan: Run a scan on any URL, no signup required
- Pro: $29/month — continuous monitoring, compliance reports
- Self-serve: Sign up and start in 60 seconds, no API code
- Flat rate: Predictable monthly cost, no per-call fees
- Designed for: Business owners without developer resources
When Tenon.io Is the Right Choice
Tenon.io serves specific use cases where API-first design adds genuine value for technical teams:
CI/CD pipeline integration
Development teams that want to automatically gate deploys on accessibility failures benefit from Tenon's API — call it from GitHub Actions, Jenkins, or CircleCI to catch WCAG regressions before code ships.
Custom accessibility reporting tools
Organizations building proprietary accessibility dashboards, internal audit tools, or compliance platforms can use Tenon's API as a reliable testing backend without maintaining their own WCAG testing engine.
Large-scale automated crawls
Enterprise teams that need to batch-test hundreds of pages programmatically can structure Tenon API calls to crawl and report across an entire site inventory — useful for agencies running accessibility audits across multiple client sites.
Testing frameworks integration
QA engineers using Selenium, Playwright, or Cypress who want to add accessibility assertions to their existing automated test suites can integrate Tenon API calls alongside functional test code.
Why RatedWithAI for Small Businesses and ADA Lawsuit Protection
Tenon.io was not designed for small businesses without engineering teams who primarily need protection from ADA Title III web accessibility lawsuits. RatedWithAI was — and the difference is fundamental:
Zero Technical Expertise Required
Using Tenon.io requires writing API integration code, handling authentication headers, parsing JSON violation reports, and building your own scheduling and reporting on top. RatedWithAI requires typing your URL into a form. A restaurant owner, retail shop, or service business can set up continuous ADA monitoring in under a minute — no developer required, no API key, no JSON parsing.
Built-In Compliance History for ADA Demand Letters
When an ADA demand letter arrives, your strongest defense is documented evidence of ongoing good-faith compliance efforts — timestamped scans showing you've been actively monitoring and remediating violations over time. RatedWithAI's Pro plan automatically builds this compliance history. Tenon.io provides raw API data; there's no built-in mechanism to generate the kind of business-facing compliance documentation that matters in an ADA lawsuit defense.
Plain-English Reports, Not Developer JSON
Tenon's API returns technical JSON — violation codes, CSS selectors, DOM paths. That's valuable for a developer fixing code. It's meaningless to a business owner trying to understand their legal risk and communicate with their web developer. RatedWithAI translates WCAG violations into business-readable reports with prioritized fix lists and ADA risk explanations — actionable for a non-technical owner.
Predictable Flat-Rate Pricing
Tenon.io's API call-based pricing means your cost varies with usage — confusing for a business owner who just wants consistent monthly monitoring. RatedWithAI Pro is a flat $29/month for continuous site monitoring. No surprise bills when your monitoring runs more frequently, no need to calculate API call volumes. Predictable compliance cost for a predictable business expense.
Start ADA Compliance Monitoring for $29/month
No API code required. No JSON to parse. Continuous WCAG monitoring, compliance history reports, and ADA lawsuit documentation — built for business owners, not developers.

Frequently Asked Questions
Is RatedWithAI a good Tenon.io alternative?
For small businesses focused on ADA lawsuit protection and continuous monitoring, yes — RatedWithAI is a far more practical Tenon.io alternative. Tenon.io requires developer expertise to use at all; RatedWithAI is designed for business owners with no technical background. Both test for WCAG 2.1 AA violations, but RatedWithAI wraps that testing in a business compliance dashboard with compliance history, plain-English reports, and ADA documentation — at $29/month with no coding.
Can a non-developer use Tenon.io?
Tenon.io is built as a developer API — using it without coding requires Tenon Studio, their supplementary dashboard product. Even with Tenon Studio, the output is oriented toward technical users who understand WCAG violation codes and DOM-level accessibility concepts. For a small business owner without technical staff, RatedWithAI provides the same underlying WCAG detection capability in a dashboard that requires no technical knowledge to operate.
What does Tenon.io check for?
Tenon.io tests for WCAG 2.1 A and AA success criteria that can be evaluated automatically — issues like missing alt text, insufficient color contrast, unlabeled form fields, missing ARIA labels, keyboard focus issues, and heading structure problems. Automated testing covers approximately 30–40% of WCAG 2.1 AA criteria; the remainder requires manual testing by a human reviewer. RatedWithAI uses the axe-core engine (industry standard) and tests the same automated-detectable WCAG criteria.
Does Tenon.io protect against ADA lawsuits?
Tenon.io is a testing tool — it helps identify WCAG violations, but it doesn't create the compliance documentation that matters in ADA lawsuit defense. The strongest defense against an ADA demand letter is a documented history of ongoing compliance monitoring and remediation efforts — timestamped records showing your good-faith effort to maintain accessibility. RatedWithAI's Pro plan is specifically designed to build this compliance history automatically. Tenon.io, as an API, requires you to build your own record-keeping on top of the raw API data.
Is Tenon.io still active in 2026?
As of 2026, Tenon.io continues to operate as an accessibility testing API. The company has evolved its product to include Tenon Studio (a dashboard layer above the API) and focuses primarily on developer and enterprise API use cases. For small businesses looking for a compliance monitoring solution without developer involvement, RatedWithAI remains the purpose-built alternative.
