Maker
📌
Hey Product Hunt! 👋
I built BeaverCheck because I was tired of juggling multiple tools just to get a full picture of a website's health. You'd run Lighthouse for performance, then check security headers somewhere else, then SEO in another tool, then accessibility in yet another — and none of them talked to each other.
BeaverCheck runs 100+ checks in a single scan across 13 categories: performance, security, SEO, accessibility, content quality, infrastructure, compliance, technology stack, and more. Just paste a URL — no signup, no credit card, no queue.
A few things I'm proud of:
-Multi-location scanning — test from different countries to see how your site performs globally
-Tech stack detection — identifies 7,500+ technologies, like a free BuiltWith alternative
-Permanent history — every scan is stored so you can track improvements over time
-Full API — integrate audits into your CI/CD pipeline or build on top of it
-Free tools — contrast checker, security headers inspector, SSL checker, DNS lookup, redirect tracer
Everything is completely free. No premium tier, no feature gates.
I'd love to hear what you think — what checks would you want to see added? What matters most when you audit a site? Happy to answer any questions!
