❓ Frequently Asked Questions
What makes this different from Lighthouse? ▼
While Lighthouse focuses on performance, our heuristic analyzer applies UX principles (Nielsen’s, accessibility heuristics) and identifies conversion friction specific to user experience and business goals. It also accepts screenshot analysis for private interfaces.
Is my data / screenshot stored? ▼
No. All analysis happens in real time; screenshots are processed in memory and never persisted. URLs are fetched anonymously.
Which UX heuristics are used? ▼
We combine Nielsen’s 10 heuristics, WCAG 2.1 accessibility guidelines, and conversion-centered design principles (Krug, CXL).
Can I test a password‑protected site? ▼
For private interfaces, please use the screenshot upload. We don’t store credentials.
