Checking whether web page checks are available…

Check form

01 / Page address

Web page address

One public page, https:// only. Private, internal and password-protected addresses cannot be checked.

02 / Verification

Complete verification before submitting.

A short anti-abuse challenge (Cloudflare Turnstile) runs before your first check; Cloudflare processes it under its own privacy terms.

Before you start

5 checks / day

Shared across the free tools (PDF, HTML and web checks) for your public IP address, one at a time; people sharing an office, campus or carrier network also share them. Resets at 00:00 UTC. Need more? See plans and prices.

Files expire after 24 hours

Download links and the scan report expire 24 hours after the check. Save what you need before then.

Human review is still required

The automated axe-core rules cover part of WCAG 2.2 AA; keyboard, content and context checks still need a person.

Automated results are not a PDF/UA or WCAG conformance certificate. Every job needs human review before any accessibility claim is made. Koldera is in beta.
