I built an accessibility scanner with an AI team in a week — and it's free

Description and use

A free accessibility scanner delivers a quick WCAG 2.2 report, enabling small agencies to answer client queries swiftly.

Problem

Small agencies need a quick answer to client questions about website accessibility, but specialist audits are too costly and time‑consuming.

Outcome

The scanner provides a quick, plain‑English accessibility overview, identifying WCAG 2.2 violations and suggesting fixes, while transparently indicating what it could not check. It is free, white‑labelled, and privacy‑preserving.

Workflow

• Paste a URL (including password‑protected staging links) into the scanner.
• The server fetches the page and up to four linked pages on the same site.
• Runs 14 concrete WCAG 2.2 checks on the server‑sent HTML.
• Generates a scored, prioritised report in plain English with suggested fixes.
• Displays any checks that could not be performed in an amber panel.
• Prints a white‑label report ready for the client.
• All changes are backed by an automated test suite (333 passing tests).

Evidence

You paste a URL — no signup, no email, no card — including password‑protected staging links.

Source

It fetches the page plus up to four linked pages on the same site and runs a fixed set of 14 concrete WCAG 2.2 checks on the server‑sent HTML.

Source

About a minute later: a scored, prioritised report in plain English, with suggested code fixes.

Source

If a check couldn't judge a page, it's listed — not guessed — in an amber "What Curbcut could not check" panel under the score, so green means you know what was actually checked.

It reads the HTML your server sends. It cannot see what a browser draws afterwards with JavaScript — carousels, cookie banners, embedded widgets — so a JS‑heavy page can score better here than it deserves.
