Frequently Asked Questions

BeaverCheck is a web performance and security analysis tool that runs 100+ checks across 11 analysis tabs in a single scan. It covers performance, security, accessibility, SEO, content quality, infrastructure, technology stack, compliance, availability, sustainability, and Lighthouse scores.

A typical scan takes 45–90 seconds. This includes two full Lighthouse audits (mobile and desktop), security header analysis, technology fingerprinting, DOM analysis, multi-viewport screenshots, and infrastructure checks.

Yes. BeaverCheck is completely free with all features available. No account required.

We currently have workers in multiple locations across Europe, North America, Asia, and South America. You choose which location to scan from.

The composite grade is a weighted average across 8 scored categories: Performance 25%, Security 25%, Accessibility 15%, SEO 10%, Infrastructure 10%, Compliance 8%, Content 5%, Sustainability 2%. See our Methodology page for full details.

Lighthouse scores vary between runs due to network conditions, server load, and test location. BeaverCheck runs Lighthouse from our dedicated servers, which may have different network paths. Small variations of 3–5 points are normal.

Yes. Every scan runs two Lighthouse audits: one emulating a mobile device and one on desktop. The result page has a toggle to compare scores. Screenshots are captured at three viewports: 375px, 768px, and 1440px.

A+ = 97–100, A = 90–96, B = 80–89, C = 70–79, D = 55–69, F = below 55. These apply to both the composite grade and individual categories.

We store scan results (scores, findings, screenshots) so you can view them later. We do not store the full HTML content of your pages. Results are publicly accessible by their unique URL.

Our JavaScript vulnerability database is updated with each deployment. Technology fingerprints cover 1,000+ technologies.

Currently all results are accessible by their unique URL but are not indexed by search engines. Private results with user accounts are planned for a future update.

Lab data (Lighthouse) is collected in a controlled environment — consistent but doesn't reflect real-world variation. Real-user data (CrUX) is the 75th percentile of actual Chrome users over 28 days. When both are available, we show them side-by-side.

BeaverCheck analyzes HTTP headers and HTML content against 1,000+ technology fingerprints. It detects CMS platforms, frameworks, servers, CDNs, analytics tools, and more.

We extract text element positions and foreground colors from the DOM, then sample actual background pixels from the desktop screenshot. This catches contrast failures on background images and gradients that CSS-only tools miss.

Yes. Every result page has a Download PDF button that generates a comprehensive report covering all 11 tabs, executive summary, composite grade, and detailed findings.
