Some read your live site and tell you what they found, in the words you would use rather than the words a scanner would, from the same audit we start a paying client from. Others build a file you copy and publish, from your DMARC records to a privacy policy. All of them tell you what they cannot see, which is the part most free tools leave out.
What none of these can tell you
Every one of them reads your site from the outside, as a stranger would. That means none of them can see your CDN rules, your server configuration, your content, or whether the thing they flagged actually matters to your business. A clean result is the absence of the faults we can measure, not proof that nothing is wrong. Where a check has a hard limit, its own page says so before it says anything else: the accessibility one cannot certify conformance, the cookie one cannot determine lawfulness, and the AI crawler one cannot see whether your firewall is turning the crawlers away regardless of what your robots.txt permits.
Checks your live site
One scan, a door for each question
They are the same audit behind one door each, not a pile of separate scanners. Running one measures everything; the page you chose decides what it leads with, and the rest of the report is yours free when you ask for it.
Gives you something to keep
Files you build yourself
None of them sends anything anywhere. They run entirely in your browser, which is worth stating plainly given one of them asks for your address and telephone number.
Or ask all the questions at once
The X-Ray runs every check on this page and several more: your security headers, your certificate, how fast the page actually loads, whether Google can index it and what your site publishes about itself. Each tick is a check that has returned. Nothing on the screen advances on a timer.
We read public pages only. We do not log in, we do not probe admin paths, and we identify ourselves in your server logs as OxwynXRay.
Would rather read than scan? The engineering notes go into the same subjects at length, including why a passing check is not the same as a solved problem.
