Web Performance Engineering in the Age of AI: Mastering Speed and Quality for AI-Generated Applications

On today's web, performance isn't just a nice—to—have—it's essential. A slow or unstable experience drives users away, while a fast, reliable one builds trust and keeps them engaged. Web Performance Engineering in the Age of AI is a comprehensive, hands—on guide for developers, technical leads, and performance engineers focused on delivering high—impact, user—first web experiences. Written by Addy Osmani, director at Google Cloud AI, this book combines deep technical insight with a strong emphasis on usability and real—world effectiveness.

Through case studies, modern optimization techniques, and a user—centered approach, you'll learn how to identify bottlenecks, debug performance issues, and apply improvements that make a measurable difference. Grounded in current browser internals and performance metrics, this book prepares you to design and maintain faster, more resilient websites at scale.

• Understand how users perceive speed—and why it matters
• Evaluate and improve performance using key metrics
• Optimize for stability, responsiveness, and load time
• Identify and address the most common performance bottlenecks
• Apply real—world strategies that lead to lasting results
