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.
