FAQPage Schema
How do I run a production audit on a live website for visual and performance issues?▼

A production audit simulates real-user interactions via browser automation to expose website weaknesses, identifying visual decay, interactive failures, console errors, and Core Web Vitals issues across multiple breakpoints.

What is Core Web Vitals measurement and how does it relate to website testing?▼

Core Web Vitals measurement evaluates real-world loading speed and interactivity using browser automation, revealing performance bottlenecks and speed analysis issues on deployed websites before they impact users.

Do I need a browser automation extension to test core web vitals and accessibility?▼

Yes, comprehensive website battle-testing that checks accessibility issues and core web vitals requires the Claude in Chrome MCP extension to interact with the live site as a user would.

Can I check for visual decay and broken interactivity across multiple device breakpoints?▼

Yes, live browser testing simulates real-user interactions across multiple breakpoints to rigorously test deployed websites, uncovering visual bugs and broken interactivity before launch.

What's the best way to perform a comprehensive website battle-test before launching a landing page?▼

The best approach combines live browser testing with speed analysis to check for console errors, performance bottlenecks, and accessibility problems, ensuring the page is visually perfect on all devices.

Why does my website testing fail to catch accessibility issues and console errors?▼

Standard testing may miss accessibility problems and console errors if it lacks browser automation to simulate real-user interactions and perform live, multi-breakpoint production auditing.
