Best Tabnav Alternative in 2026: Why Continuous Monitoring Beats One-Time Scans

What Is Tabnav?

Tabnav is an accessibility solutions provider that offers three main products: a free one-page accessibility checker, a paid monitoring platform, and an accessibility overlay widget. Based on their G2 reviews and website, they position themselves as an "end-to-end accessibility solution" covering scanning, fixing, and maintaining compliance.

Their free checker lets you scan any single page for WCAG, ADA, and EAA issues without signing up — which is genuinely useful for quick spot-checks. They also offer a WCAG Academy with free educational content, which is a nice touch.

However, Tabnav's approach centers heavily on their accessibility widget — an overlay that adds keyboard navigation, contrast settings, and text controls to your website. This is where things get complicated, because the accessibility community has serious concerns about overlay widgets as a compliance strategy.

The Overlay Problem: Why Widgets Don't Equal Compliance

Tabnav's most prominent product is their accessibility widget, starting at $39/month. Overlay widgets add a toolbar or floating button to your site that visitors can use to adjust font sizes, contrast, spacing, and enable a screen reader mode.

The appeal is obvious: install a JavaScript snippet and your site becomes "accessible." But here's what the overlay model gets wrong:

• Overlays don't fix code-level issues. Missing alt text, broken heading hierarchies, inaccessible forms, and missing ARIA labels remain broken underneath the widget. Screen readers still encounter these barriers because they interact with the actual DOM, not the overlay.
• Screen reader users often disable overlays. The National Federation of the Blind (NFB) has publicly criticized overlay solutions. Many assistive technology users report that overlays actually interfere with their existing tools rather than helping.
• Overlays haven't prevented lawsuits. Multiple companies using accessiBe and similar overlay products have been sued — and lost. Courts have consistently ruled that overlays alone do not satisfy ADA requirements. In fact, companies using overlays may face more lawsuits because plaintiff firms specifically target them.
• The Overlay Fact Sheet — signed by hundreds of accessibility professionals — states clearly: "overlay widgets do not provide sufficient accessibility." This isn't a fringe opinion; it's the mainstream view of the accessibility community.

To be fair, Tabnav also offers genuine scanning and monitoring tools beyond their widget. But the prominence of the overlay product in their marketing — and the fact that it's their cheapest paid option — raises questions about whether customers are getting the right advice about what actually makes a website compliant.

How RatedWithAI Takes a Different Approach

RatedWithAI deliberately chose not to offer an overlay widget. Instead, we focus entirely on what actually works: finding real accessibility issues in your code and helping you fix them.

Here's what that means in practice:

• axe-core scanning engine: We use the same engine that powers Google Lighthouse's accessibility audits. Axe-core is maintained by Deque Systems, the world's leading accessibility consultancy, and is specifically designed for zero false positives. Every issue we flag is a real violation.
• Continuous monitoring: Unlike a one-time scan, we track your accessibility score over time. Deploy a new feature? We'll catch if it introduced regressions. Fix a batch of issues? Watch your score improve on the dashboard. This continuous feedback loop is what actually drives improvement.
• Code-level fix guidance: Every violation includes the specific HTML element, what's wrong, and exactly how to fix it. No generic advice — actual code snippets you can hand to your developer.
• Free tools that add value: Our Color Contrast Checker, Alt Text Generator, and PDF Accessibility Checker help you fix specific issues as you encounter them — no subscription needed.

Pricing Comparison: Where Your Budget Goes

Let's break down what you're actually paying for with each tool:

If you want both scanning/monitoring and a widget from Tabnav, you're looking at $108/month minimum. With RatedWithAI, you get continuous monitoring, score tracking, and a full suite of free tools for $29/month — and no overlay widget, because we believe fixing your actual code is the right approach.

That's a 73% cost savings on monitoring alone ($29 vs $69), and the money you save isn't going toward an overlay that accessibility experts recommend against.

One-Time Scans vs Continuous Monitoring: Why It Matters

Tabnav's free checker is genuinely useful — we're not going to pretend otherwise. Being able to scan any page without signing up is great for quick checks. But here's the fundamental limitation of one-time scanning:

A one-time scan tells you where you stand right now. Continuous monitoring tells you whether you're getting better or worse — and catches regressions before they become lawsuit targets.

With RatedWithAI, every monitoring scan updates your accessibility score, so you can see trends over weeks and months. You'll know immediately if a deployment broke something, and you can demonstrate ongoing compliance effort — which courts have recognized as a strong defense in ADA litigation.

Where Tabnav Excels

We're not here to bash Tabnav — they have genuine strengths:

• Free unlimited scans: Their one-page checker is truly unlimited with no signup. That's generous and useful for quick spot-checks during development.
• WCAG Academy: Free educational content that teaches WCAG best practices with do's, don'ts, and real use cases. Education is valuable regardless of which tool you use.
• PDF remediation: AI-powered PDF accessibility remediation is a strong feature. Inaccessible PDFs are a major compliance gap that many tools ignore entirely.
• Manual audit services: For organizations that need expert human review beyond automated scanning, Tabnav offers custom accessibility auditing and remediation services.

If your primary need is a one-time accessibility audit with manual remediation, Tabnav's custom solutions may be worth exploring. But for ongoing compliance monitoring at a reasonable price, RatedWithAI is purpose-built for that job.

Scanning Engine: Axe-Core vs Proprietary

One of the most important differences between any two accessibility tools is their scanning engine — the technology that actually finds issues on your page.

Tabnav uses a proprietary scanner. They describe it as an "advanced scanning approach that reflects real behavior and finds issues other checkers miss." Without transparency into how their engine works, it's difficult to evaluate the accuracy and coverage of their results independently.

RatedWithAI uses axe-core — the open-source accessibility testing engine maintained by Deque Systems. Axe-core is:

• The industry standard — used by Google Lighthouse, Microsoft Accessibility Insights, Chrome DevTools, and thousands of development teams worldwide.
• Open source and auditable — anyone can inspect the rules, verify the logic, and contribute improvements. No black box.
• Designed for zero false positives — Deque's engineering philosophy prioritizes accuracy over quantity. If axe flags something, it's a real issue. This matters because false positives waste developer time and erode trust in the tool.
• Continuously updated — new WCAG criteria, browser behavior changes, and ARIA spec updates are incorporated by the Deque team, which includes some of the world's foremost accessibility researchers.

Who Should Choose Tabnav?

Tabnav may be a better fit if you:

• Need a one-time accessibility audit with manual remediation services
• Want PDF remediation as a core feature
• Prefer an all-in-one vendor that handles scanning, fixing, and widget delivery under one contract
• Your team needs hands-on support and dedicated project management for a large remediation project

Who Should Choose RatedWithAI?

RatedWithAI is built for teams who want:

• Continuous monitoring that tracks accessibility over time — not just point-in-time snapshots
• Lower cost — $29/mo vs $69/mo+ for comparable monitoring features
• Code-level fixes, not overlays — we help you build accessibility into your site, not paint over problems
• Industry-standard accuracy — the axe-core engine with zero false positives
• Free tools for ongoing work — contrast checking, alt text generation, PDF checking, and VPAT templates
• Compliance documentation — score history and improvement tracking for legal defense and audit purposes

The Bottom Line

Tabnav isn't a bad tool — their free scanner is useful and their educational content is solid. But their business model leans heavily on an overlay widget ($39/mo) that the accessibility community has serious concerns about, and their monitoring plans start at $69/mo — more than double what you'd pay with RatedWithAI.

If you're serious about web accessibility, you need a tool that:

1. Finds real issues in your code using a proven, auditable engine
2. Tracks your progress over time so you can demonstrate ongoing compliance
3. Helps you fix things with specific, actionable guidance — not generic widget functionality
4. Doesn't break the bank — accessibility should be affordable enough that every business can prioritize it

That's exactly what we built RatedWithAI to do.
