What Is Tenon.io?
Tenon.io is an accessibility testing platform built around a REST API. Unlike monitoring tools that give you a dashboard to log into, Tenon is designed to be called programmatically — from your build scripts, test suites, CI/CD pipelines, or automation frameworks. You pass a URL or HTML snippet to the API and get back a JSON response with a list of WCAG violations.
Founded by accessibility expert Karl Groves, Tenon was one of the first API-first accessibility testing services and helped establish the pattern of integrating WCAG scanning into development workflows. The platform uses its own scanning engine alongside integrations with popular testing frameworks like Jest, Mocha, and Selenium.
Tenon is best suited to developer teams that want to catch accessibility issues before they ship — not organizations looking for a non-technical monitoring dashboard. If you want to run scans from your terminal and fail builds on WCAG violations, Tenon is designed for you.
Tenon Pricing Plans Explained
Free Plan
$0/monthTenon's free tier gives developers API access with a limited number of monthly API calls. It's enough to evaluate the platform, integrate the API into a test project, and run occasional scans. Not suitable for production pipelines with frequent builds.
Included:
- • API access (limited calls/month)
- • WCAG 2.1 scanning
- • JSON results output
- • Basic documentation access
Limitations:
- • Low monthly API call cap
- • No team collaboration features
- • No priority support
- • Not suitable for production CI/CD at scale
Developer Plan
~$50–$80/monthThe Developer plan is designed for individual developers who want to run accessibility tests as part of their CI/CD workflow. You get enough API calls to support regular builds in a single-developer or small-project context.
Included:
- • Higher monthly API call limit
- • WCAG 2.1/2.2 scanning
- • CI/CD integration support
- • Email support
Good for:
- • Freelancers building accessible client sites
- • Individual developers integrating accessibility
- • Small projects with infrequent builds
- • Accessibility consultants auditing client code
Team Plan
~$200–$500/monthThe Team plan scales to support multiple developers and higher build frequencies. It's designed for engineering teams that have committed to integrating accessibility testing into their standard development workflow.
Included:
- • High monthly API call limits
- • Multiple team member seats
- • Advanced reporting
- • Priority support
- • Webhook notifications
Good for:
- • Dev teams of 3–15 engineers
- • Organizations with daily CI/CD pipelines
- • Mid-size apps with multiple components
Enterprise Plan
Custom pricingEnterprise plans are custom-priced based on scan volume, team size, and organizational requirements. These plans include higher API limits, dedicated support, custom integrations, and SLA guarantees. Contact Tenon's sales team for a quote.
Typically includes:
- • Unlimited or very high API call volumes
- • Dedicated account manager
- • Custom SLA and uptime guarantees
- • On-premises deployment options (if required)
- • Custom integrations and professional services
Is Tenon Worth the Price?
Tenon is worth it for developer teams that want an API-first WCAG testing solution and have already evaluated the alternatives. The platform is clean, the API is well-documented, and integration into CI/CD pipelines is straightforward.
That said, Tenon faces strong competition from Deque axe DevTools, which offers a free browser extension, a widely-used open-source engine (axe-core), and an established ecosystem of integrations. Most developer teams reach for axe-core first — it's embedded in most accessibility testing frameworks by default.
When Tenon makes sense:
- • Your team prefers a dedicated commercial API with support SLAs over open-source tooling
- • You need a vendor relationship and billing for procurement requirements
- • You want professional services and consulting available from Tenon's team
- • You've evaluated axe DevTools and prefer Tenon's results
When to look elsewhere:
- • For free CI/CD scanning: use axe-core (open-source) or the free axe browser extension
- • For non-technical monitoring dashboards: use RatedWithAI, AudioEye, or Siteimprove
- • For enterprise compliance programs: use Level Access or Siteimprove
- • For budget-conscious teams: axe-core is free and covers most of the same WCAG rules

|---|---|---|---|
| Tenon.io | ~$50/month | Yes (limited) | API-first CI/CD |
| axe-core (open source) | Free | Yes (fully free) | CI/CD, open source projects |
| axe DevTools Pro | ~$79/month | Yes (browser extension) | Developer CI/CD + dashboard |
| RatedWithAI | $29/month | Yes | Monitoring dashboard, SMBs |
| AudioEye | $49/month | Free scan | Mid-market, overlay + monitoring |
| Siteimprove | $5K+/year | No | Enterprise web governance |

Tenon Pricing FAQ
Does Tenon offer a free trial?
Tenon offers a free tier with limited monthly API calls, which effectively serves as a free trial. You can sign up and start making API calls without a credit card to evaluate whether the platform works for your use case. For production use, you'll need a paid plan.
Is Tenon.io still actively maintained in 2026?
Tenon.io has been one of the longer-running API-first accessibility testing platforms. As of our research in June 2026, the platform remains active. That said, the competitive landscape has intensified — axe-core (free, open source) has become deeply embedded in most development stacks, making the commercial API value proposition harder to justify for teams that are comfortable with open-source tooling. Check their website for current status and pricing.
What WCAG standards does Tenon test against?
Tenon tests against WCAG 2.1 and WCAG 2.2 success criteria at Level A and AA. The platform catches automatically detectable WCAG violations — approximately 30–57% of all potential issues. Like all automated tools, it cannot catch issues that require human judgment (color contrast edge cases, meaningful alternative text evaluation, keyboard navigation flow issues that depend on context).
What are the best Tenon alternatives?
The best Tenon alternative depends on your use case. For developer CI/CD integration, axe-core (free, open source) or axe DevTools Pro are the most widely used options. For non-technical teams that want a monitoring dashboard, RatedWithAI ($29/month) is a more accessible entry point. See our Tenon alternatives guide for a full comparison.
Need WCAG Monitoring Without the API Complexity?
RatedWithAI provides automated WCAG 2.1/2.2 scanning and monitoring for $29/month — no API setup required. Get actionable accessibility reports with a simple dashboard, not a REST API.
