For accessibility engineers, and everyone who wants to become one
Made in Europe
Human-led, not just automated
Built by VU Amsterdam alumni
From finding to fix
Trace every issue to the component that caused it, test it across the flows people actually use, and turn it into a report you can hand off.
A score per project
Every project gets scanned continuously and scored on a 0-100 scale, so you can see accessibility improve or slip week over week instead of finding out at the next audit.
Findings mapped to WCAG
Each issue arrives graded by severity and tied to the exact WCAG rule it relates to, with the page and element it occurs on. Assign it to a teammate and track it from open to resolved, right alongside the rest of your team's work.
Component-level fixes
Connect your design system - a private npm registry, components/ui, shadcn - and every component gets its own pass/fail status, occurrence count, and fix guide. One inaccessible button gets found a single time, before it ships into a hundred pages.
User flow testing
Check multi-step flows - checkout, onboarding, sign-up - step by step, on a schedule or on every deploy. When a step fails, like a modal that doesn't trap focus, you see exactly which step and why.
Compliance reports
Set a conformance target - WCAG 2.1 AA, for example - and track criteria met against it. Generate the report someone actually asked for - EN 301 549, VPAT 2.5/ACR, Section 508, AODA - and check statement readiness before you send it.
Structured manual review
Work through every WCAG criterion one by one, marked passed, failed, N/A, or still to review, with an overall percent reviewed. Automation catches a large share of issues, but full conformance still needs this kind of human judgment - and it feeds into the same findings and reports as the automated scans.
Works with your stack
Runs against apps built with any of the following frameworks, and connects to the tools your team already uses.
Questions
When can I use Accessibility Inspector?
Accessibility Inspector is currently a research preview and not publicly available yet. There's no fixed launch date - joining the waitlist just means we'll email you as soon as you can sign up.
What will it cost?
Pricing isn't final yet. It will be announced before launch - waitlist members will simply be the first to hear when it is.
Does it replace a manual accessibility audit?
No - and no automated tool honestly can. Automated checks catch a large share of WCAG issues continuously, between releases. For full conformance you still need human review, which is why Accessibility Inspector includes structured manual-audit workflows alongside the automated scans.
Which standards does it cover?
Findings map to individual WCAG success criteria (levels A, AA, AAA), and reports translate them into the frameworks teams are asked about: EN 301 549, Section 508, VPAT 2.5 / ACR, and AODA.
How does it handle single-page applications?
It drives a real browser through your routes, states, and interactions - the way a user actually clicks through a React, Vue, Svelte, or Angular app - and audits every rendered view, not just the initial HTML.
How is this different from a tool like axe-core?
Axe-core and similar scanners check the first render of a page. Accessibility Inspector drives a real browser through your actual routes and states, tests components at the design-system level so a fix applies everywhere at once, and covers multi-step user flows like checkout - on top of the same rule-based checks.
