Speed & Performance
Speed is revenue · why AI-generated apps ship slow, how performance becomes a security problem, and what actually makes them fast.
- Performance as a Security Risk: How Slow Code Creates Vulnerabilities · Slow code is a major security risk: blocking I/O, N+1 query patterns, and missing timeouts allow attackers to trigger application-level Denial of Service (DoS) with minimal traffic. By exploiting unoptimized AI-generated logic, malicious users can exhaust server resources or database connection pools, crashing your app for all users.
- Why Your AI-Built App Is Slow (And How to Fix It) · AI-built apps are typically 500ms to 1500ms slower than necessary due to redundant auth calls, heavy JS bundles, and render-blocking spinners. SimplyScan's analysis shows many apps suffer from these speed issues. Fixing them via code splitting and CSS animations can reduce bundle sizes and significantly boost user conversions.
- Speed = Revenue: What the Data Says About Faster Apps · Speed measurably drives revenue: Amazon loses 1% of sales per 100ms of delay, Walmart gains 2% conversions per second saved, Pinterest's 40% faster pages lifted signups 15%, and 53% of mobile visitors abandon sites slower than 3 seconds. Every 100 milliseconds of improvement produces a measurable lift in conversions, engagement, and revenue.
- Why Cursor, Lovable, and Bolt Don't Optimize Your App's Speed (And What Does) · Cursor, Lovable, and Bolt.new optimize for development speed, not runtime performance. They often skip code splitting, query deduplication, and asset optimization. SimplyScan’s data shows 71% of AI-built apps have speed issues. Our scanner identifies these AI-specific bottlenecks in 30 seconds, providing exact code fixes to recover lost conversions.
- Why Your Vibe-Coded App Needs Uptime Monitoring · Vibe-coded apps fail quietly due to serverless cold starts, expired API keys, and sleeping databases. Uptime monitoring pings your URL every few minutes to alert you before customers do, while a public status page builds trust. SimplyScan’s Uptime tab sets both up in seconds, ensuring your AI-built app stays reliable.
