Where Sitebulb is the better choice
For enterprise-scale technical SEO auditing - crawling hundreds of thousands of URLs and actually being able to see how they connect, not just get a list of issues - Sitebulb's crawl visualization is a genuinely distinct strength Scanverra doesn't attempt to replicate. If your team's workflow depends on that kind of visual, large-scale crawl mapping, it's the right tool for that job specifically.
Where Scanverra is the better choice
Sitebulb requires a desktop install (or a Cloud plan starting at £95/month) and has no performance lab testing, no security scanning, and no AI-generated fixes - it's a crawler, not an audit-and-fix platform, and it has no free tier at all. Scanverra runs entirely in the browser, turns around a single page's full audit in under a minute for free, and adds security, accessibility, and AI-fix scope beyond pure crawling.
Frequently asked questions
Can Scanverra crawl an entire site the way Sitebulb does?
No - this is an honest, real gap. Scanverra crawls a bounded same-origin queue per scan, not a whole site. Sitebulb's desktop Pro plan handles up to 500,000 URLs per audit and is purpose-built for enterprise-scale technical SEO crawls that Scanverra doesn't attempt.
Does Sitebulb have a free plan?
No - Sitebulb is paid-only, with a 14-day free trial and no permanent free tier. Scanverra's Website Audit, by contrast, is free and unlimited indefinitely, with the other three tools (Security Scanner, Browser Tester, Repo Scanner) offering a free monthly allowance.
Does Sitebulb check performance or security?
Its scope is technical SEO auditing and crawl visualization - it doesn't run a Lighthouse-style lab performance test or analyze HTTP security headers, TLS configuration, or exposed secrets the way Scanverra's Website Audit and Security Scanner do.
What does Sitebulb do that Scanverra doesn't?
Its visual crawl maps - seeing how a site's internal linking structure actually connects, page by page, at genuine scale - are a real, distinct strength Scanverra has no equivalent of. For enterprise-scale technical SEO auditing workflows, that visualization is Sitebulb's core value.
