BeaverCheck's answer
Unlike GTmetrix or PageSpeed Insights which focus on performance only, BeaverCheck covers security headers, SSL, DNS, accessibility, SEO, legal compliance, and technology detection in a single scan. It's completely free with no account required, includes PDF and Markdown report exports, embeddable badges, and a free REST API.
BeaverCheck's answer
Web developers, DevOps engineers, SEO professionals, and digital agencies who need a comprehensive website health check without juggling multiple tools. Also used by freelancers auditing client sites and developers monitoring their own projects.
BeaverCheck's answer
BeaverCheck was built out of frustration with needing 5+ different tools to get a full picture of a website's health. We wanted one tool that runs Lighthouse, checks security headers, analyzes SSL, inspects DNS, validates accessibility, and detects technologies — all from one URL paste, with no friction.
BeaverCheck's answer
Go, Google Lighthouse, SQLite, htmx, Alpine.js, Tailwind CSS, Playwright, and Chromium. Workers run distributed across 6 locations worldwide (Amsterdam, New York, Singapore, Santa Clara, Sao Paulo, Madrid).
BeaverCheck's answer
BeaverCheck is a free public tool — anyone can use it without an account. It's used by individual developers, freelancers, and small agencies. We focus on being the best free option rather than targeting enterprise customers.
