🕵️New · live-click audit powered by a real browser
The bug detective that clicks every button on your site — before your users do
Opens a real headless browser, walks every priority page, clicks every link and button, and reports back in under 60 seconds. Finds 404s, 500s, dead-ends, broken flows, and JavaScript errors that static scanners miss.
Homepage first, then pricing, checkout, signup, and sitemap-derived top pages. Your highest-traffic paths get scanned before the rest.

2. Clicks every interactive element
Real headless Chromium interacts with <a>, <button>,[role=button], and [onclick] elements — not just parses HTML.

FAQ
Does the scanner respect robots.txt?
Yes, unconditionally. We also identify as NexusBroBot/1.0 and default to 1 request per second per hostname on the free tier.
Can I scan sites I don't own?
You can — but only public pages, and only at a polite rate. We never attempt to bypass CAPTCHAs, rate limits, or authentication.
What's different from a static SEO tool?
Static tools parse HTML. NB Detective opens a browser and actually clicks. That's how it catches SPA dead-ends, empty href="#" buttons, and runtime JavaScript errors that only show up after user interaction.
How fast will I see results?
Free tier typically finishes in 60–120 seconds. SP (10-agent swarm) scans 500 pages in under 5 minutes. SP Max (50-agent + scheduled) runs overnight and emails you the delta.
