Three steps. Under 30 seconds.
Paste your URL
Any public URL works — staging, production, or a client's live site. No install. No setup.
We scan it
A headless browser runs up to 17 checks across accessibility, SEO, and launch readiness — mapped to WCAG 2.2 AA and EAA 2025 standards.
Get your report
Every check returns pass, amber, or fail — with a one-line fix attached. Share the link instantly. No login required for your first 5 checks.
Two views. One for you. One for your developer.
Every issue has an Owner View — plain English, business impact, what to ask for — and a Developer View with step-by-step fix instructions, WCAG references, and effort estimates.
Who is affected
People who are blind or have low vision and use a screen reader to navigate the web.
Why it matters
Screen reader users will hear nothing when they reach these images. This is a direct EAA compliance risk affecting roughly 1 in 6 people.
What to do next
Forward this report to your developer and ask them to add a text description to every meaningful image.
Fix instruction
Add an alt attribute to every <img> element. Decorative images use alt="".
