The only tool that combines SEO, performance, accessibility, and security in one scan. AI-powered with plain-English recommendations.

Free

Open-source auditing tool built into Chrome. Powerful but technical, with no competitor analysis or automated scheduling.

Screaming Frog

Free (limited) / $259/yr

Industry-standard SEO crawler. Requires installation and technical expertise. No AI insights, accessibility checks, or cloud access.

Ahrefs

Enterprise-grade SEO platform with exceptional backlink data. Expensive for small teams, no accessibility or built-in performance audits.

Why Choose Scanly?

While each tool has its strengths, Scanly stands out by combining comprehensive analysis with AI-powered accessibility. Unlike PageSpeed Insights which focuses only on performance, or Screaming Frog which requires local installation and technical expertise, Scanly provides an all-in-one solution accessible to everyone.

The key differentiator is breadth versus depth. Ahrefs and SEMrush are exceptional at what they do — backlink analysis and keyword research — but they cost $129-$999/month and leave gaps in accessibility, security, and Core Web Vitals analysis. Scanly fills those gaps at a fraction of the cost.
