Harpoon Accessibility

Find what’s broken on your page, and exactly how to fix it.

Mend by Harpoon is the free Chrome accessibility auditor. It checks the active tab against WCAG and turns scanner output into a practical to-do list.

Add Mend to Chrome Open Accessibility projects

Saved audits now live beside Performance in Harpoon projects. Hosted Accessibility monitoring remains in the existing Mend portal until the monitoring rollout is complete.

01 — Why Mend

A scanner should leave you knowing what to do next.

01

The fix comes first

Every issue starts with what to change, followed by the WCAG context and a practical example.

02

Local by default

The free extension scans the active tab in your browser. It sends nothing unless you explicitly connect and save a run.

03

Built for real pages

Audit the rendered page in front of you, including local development and signed-in states the browser can already see.

04

Deterministic results

Accessibility findings come from the pinned audit engine. They are not invented or classified by a language model.

02 — How it works

Three steps, then a to-do list.

  1. STEP 01

    Open the side panel

    Dock Mend beside the page you want to inspect.

  2. STEP 02

    Run the audit

    Mend checks the rendered tab against its enabled WCAG rules.

  3. STEP 03

    Work issue by issue

    Review the fix, locate the affected element, and verify the page again.

Free in the browser

No account needed to scan.

Install Mend by Harpoon and audit as often as you need. When you want shared history, reconnect the extension explicitly to a Harpoon website project.
