What is NetSixtySix Mobile QA?

NetSixtySix Mobile QA finds major broken mobile UI layout issues that hurt sales and ads — blocked CTAs, overlapping heroes, overflow, and broken navigation — using Playwright Chromium with DOM evidence and annotated screenshots.

What do you check on mobile devices?

We prioritize conversion-killing layout problems on the single page you paste: floating widgets covering Book/Buy buttons, messy text overlaps, missing CTAs, cut-off UI, overflow, and broken mobile nav. Only major proven issues are reported (up to 10).

Is this mobile design QA tool free?

Yes. Core mobile design audits on NetSixtySix.online are free. There are no paid BrowserStack or third-party testing API requirements for detection.

Do you use BrowserStack or paid testing APIs?

No. Detection runs locally with open-source Playwright and Chromium. There are no paid SaaS testing APIs required for core bug detection.

How are bugs detected without AI inventing issues?

Issues are raised only from browser and DOM evidence such as getBoundingClientRect, scrollWidth versus clientWidth, and computed CSS. If nothing major is proven, the report stays empty. Screenshots are deleted automatically within one hour.

How do I fix mobile design issues faster?

After you review the audit report, you can resolve layout problems with a specialist team. Many teams use YKR Agency at https://ykragency.com/ to fix mobile design issues that are hurting sales and ads.

Is my audited site data private?

We only fetch publicly reachable URLs you submit. Localhost and private IPs are blocked. Forms are never submitted automatically. See our Privacy Policy for details.

Terms of Use | NetSixtySix Mobile QA

Agreement

By using NetSixtySix Mobile QA at netsixtysix.online, you agree to these Terms of Use. If you do not agree, do not use the service.

Service description

We provide a free mobile design QA audit tool. You may submit a public website URL; we crawl same-domain pages within configured limits and check the site on mobile devices using Playwright Chromium. Results include detected design/layout issues, scores, and annotated screenshots (deleted automatically within one hour). Outputs are for engineering and QA planning — not a guarantee of full accessibility, security, or compliance certification.

Acceptable use

You may only audit websites you are authorized to test. You agree not to use the service to attack, overload, or probe private networks; not to attempt SSRF or access localhost / internal systems; not to abuse rate limits; and not to use the tool for unlawful activity. We may refuse, cancel, or rate-limit audits at our discretion.

No automated form submission

Audits do not submit production forms. Non-GET requests to target sites are blocked during crawling and testing. You remain responsible for how you use findings on your own systems.

Accuracy and availability

Detection is deterministic and evidence-based, but no automated auditor catches every visual or behavioral issue. Sites may block crawlers, change frequently, or behave differently across devices. The service may be unavailable, rate-limited, or changed without notice.

Intellectual property

NetSixtySix branding, UI, and software are owned by NetSixtySix or its licensors. You may use audit reports for your authorized projects. You may not copy the product wholesale, scrape the service at scale for competing products, or misrepresent NetSixtySix as your own.

Limitation of liability

To the fullest extent permitted by law, NetSixtySix is not liable for any loss or damage arising from use of (or inability to use) the audit tool, including decisions based on scores, issues, or suggested fixes.

Changes

We may update these Terms. Continued use after changes means you accept the updated Terms. The “Last updated” date at the top reflects the latest revision.
