Considering a Sitebulb alternative? Sitebulb's crawl maps and large-site audits go further than Scanverra's 25-page SEO crawl. Scanverra is the Sitebulb alternative for teams that want a free starting point and one report covering SEO, performance, accessibility and security for their key pages.
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
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.
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.
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.
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.
