How to Diagnose Slow Load Times with OpenClaw
Diagnose page speed issues with OpenClaw and ToolRouter. Lighthouse-powered load time analysis.
Tool
OpenClaw diagnoses slow load times across multiple pages simultaneously, producing a structured breakdown of performance bottlenecks per URL. The batch analysis reveals patterns like a heavy third-party script appearing on every page, enabling you to target fixes that improve performance site-wide rather than page by page.
