Professional Website Performance Checker for Founders and Businesses
Advanced speed and user experience analysis to reduce bounce rates and improve conversions. Whether you're a startup founder or running an established business, having complete visibility into your website's security and performance is crucial.
Our website performance checker uses 15+ specialized scanners to analyze every aspect of your website. We check core web vitals (lcp, cls, inp) analysis, page load time & mobile performance, image optimization & modern format usage, and much more.
The average website has 10 issues in this category alone, with 30% being critical severity. Finding and fixing these issues before they cause problems is what FounderScan does best.
Unlike other tools that focus on just one aspect, FounderScan provides comprehensive analysis across all four dimensions: Security (35%), SEO (25%), Performance (25%), and Compliance (15%). This gives you a complete picture of your website's health.
