“Absence of evidence is not evidence of absence.”
An accessibility scanner that tests what page-level tools can't reach
Page-level scanners stop at the DOM. We launch a headless browser, Tab through your entire checkout, analyze the accessibility tree, trigger form errors, and test payment iframes — all automatically.
Scan Your Site FreeKeyboard Navigation Testing
We Tab through your entire checkout. Every button, link, and input — tested without a mouse. No other automated tool does this.
- Tab order analysis with focus trap detection
- Visible focus indicator verification
- Interactive element reachability testing
- Skip navigation link validation
- Enter/Space activation verification
Screen Reader Simulation
We analyze exactly what VoiceOver and NVDA would announce. Missing labels, broken headings, invisible content — caught automatically.
- Full accessibility tree snapshot analysis
- Image alt text verification
- Form input label associations
- Heading hierarchy validation
- Landmark region detection
Error Handling Verification
We trigger your form errors and verify they're announced properly. Broken error messages are the #1 accessibility lawsuit trigger.
- Form submission without required fields
- Error message role='alert' verification
- aria-describedby/aria-errormessage associations
- Focus management after validation failure
- Inline validation message testing
Payment Iframe Analysis
Stripe, Braintree, Adyen — we test the iframes other scanners skip entirely. Cross-origin payment forms analyzed via Claude Vision AI.
- Cross-origin iframe detection
- Claude Vision API screenshot analysis
- Iframe title and ARIA attribute verification
- Payment provider identification
- Container accessibility checks
24-Rule WCAG Engine
Comprehensive WCAG 2.2 AA compliance checking that goes beyond the basics. Alt text, color contrast, form labels, heading hierarchy, and more.
- WCAG 2.2 Level A + AA coverage
- Color contrast ratio calculation
- Form accessibility validation
- Link text quality assessment
- European Accessibility Act (EAA) mapping
How We Compare
Most accessibility tools only check static HTML. We go deeper — testing the interactive behaviors that actually block users with disabilities.

Built by a solo founder in Cape Elizabeth, Maine
Who Built This?
Chris Edwards
Solo Founder & Builder
SmarterTariff was built from scratch by one person — a climate-focused product manager, Climatebase Cohort 8 Fellow, and new dad based in Cape Elizabeth, Maine. No venture funding, no team of twelve, no AI hype deck. Just a laptop, a mission to do good, and a lot of late nights while expecting a baby.
The goal is simple: build tools that help businesses verify their supply chains are accessible, compliant, and honestly sourced — for everyone, everywhere. Every feature on this site was designed, coded, and shipped solo.
