About the Book

Vibe coding has taken the software industry by storm since Andrej Karpathy coined the term in February 2025. What started as a provocative idea has become a $4.7 billion market, reshaping how startups build products and how enterprises approach software delivery. But can vibe coding be trusted to deliver production-grade systems? This book answers that question with evidence, not hype.

Drawing on the latest research from METR, CodeRabbit, Veracode, GitClear, and others, this book presents a comprehensive framework for building serious SaaS products using AI-assisted development workflows. It covers everything from idea validation through architecture, backend and frontend engineering, security, testing, DevOps, team governance, and business growth. Every chapter combines real-world case studies with practical frameworks, checklists, and reusable prompts that you can apply immediately.
