Website check · free
Where does your website really stand?
0x41 Labs checks your website the way visitors, Google and AI assistants see it: security, privacy, loading speed, findability and usability. Every finding is backed by evidence and confirmed in a second pass. You receive the report as a PDF within 2–3 business days.
- Free and without obligation
- Only publicly visible content
- Every finding checked twice
What is checked
Six areas, one report
Security
Encryption, certificate, security headers, outdated CMS versions and libraries with known vulnerabilities.
Privacy & legal
What loads before consent (tracking, fonts, embedded services), legal notice and privacy policy.
Loading speed
Measured with Google PageSpeed and — where available — real-user data from the Chrome UX Report.
Google & AI search
Titles, structure, broken links, structured data, and whether ChatGPT, Perplexity & co. can read the content.
Accessibility
Contrast, labels and structure against the automatically testable WCAG criteria.
Design & usability
First impression, smartphone display, contact paths — with screenshots and a draft of how it could look.
How it works
From request to report
- 01
Confirm the request
After submitting, an email with a confirmation link arrives. This ensures nobody enters someone else’s address.
- 02
Check
The website is loaded like on a first visit — on desktop and smartphone, without consenting to cookies.
- 03
Second pass
Every finding is confirmed again with a different method. Whatever cannot be proven stays out of the report.
- 04
Report
A PDF with rating, evidence and the direction of the fix. On request, an offer with a clear price follows.
What the check does not do
- No attacks, no login attempts, no submitted forms, no protected areas.
- No legal advice: notes on the legal notice and privacy policy point out issues; they do not replace a lawyer’s review.
- No selling of data, no disclosure to third parties for advertising.
I look at every report before it goes out to you.
Frequently asked questions
No. The report is free and without obligation. If you want support afterwards, you receive an offer with a clear price.
The report usually arrives by email within 2–3 business days after your confirmation.
Details on vulnerabilities would be a guide for attackers. They are therefore only sent to an address that belongs to the checked website. With another address, the report contains all other areas.
Your details are only used for the check and the report. Without an engagement they are deleted no later than 180 days after the last contact. Every email contains an unsubscribe link.
