FAQ

Which browsers do you test?

We test 50+ user agents including Chrome, Firefox, Safari, Edge, Opera, Brave, Lynx, w3m, Wget, curl, Googlebot, and many more niche and legacy browsers.

How does block detection work?

Our headless farm sends real requests from each user agent and compares response codes, redirects, CAPTCHA pages, and rendered content to flag any browser-specific blocking.

Can I test sites protected by Cloudflare?

Yes. We specifically designed BrowserCheck to surface Cloudflare Bot Fight Mode and similar WAF rules that silently block non-mainstream browsers.
