Beta in preparation. The N0 diagnosis opens on 1 December 2026; today this page only shows an example and sends no data.

The beta opens on 1 December 2026

Meanwhile, see an example of what the result looks like. This page is in demo mode: it sends no data and the example uses a made-up domain.

Let’s talk

What it does and what it does not do

You confirm your emailWe send you a link. Until you click it, nothing else happens.
You prove the domain is yoursWith a TXT record or a file at /.well-known/oem-verify.txt. The code expires after 72 hours.
We read only public dataThe domain’s DNS records and one visit to the home page, like a browser: up to 5 requests, without reading the content.
You get the gradeFrom A to F, with up to 5 gaps, on screen and as a PDF. It is deleted after 90 days.

What we never do

We do not scan ports, test vulnerabilities, try to log in or visit other pages or subdomains. It is not a pentest or a certification.

Beta limits

One N0 per domain every 30 days, up to 3 domains per email or connection per month, and a daily quota. If it is full, your request is queued.
