What it is

An automated design and engineering check, in about a minute.

0x scans a live site the way a browser and a search engine see it, runs 39 checks across 10 areas, and tells you in plain English what's costing you signups, trust and search rankings, and what to fix first.

Speed

Response time, page weight, compression and real load speed.

SEO & metadata

Title, description, social previews, canonical, structured data, sitemap.

Accessibility

Headings, alt text, contrast, form labels and link text.

Mobile

Mobile viewport and favicon.

Security headers

HTTPS, HSTS, CSP, clickjacking and MIME-sniffing protection.

Link health

Broken internal links and unsafe external links.

Trust

Contact details, privacy policy and social proof.

Interactivity

We click sample buttons in a real browser to check they respond.
