## AI overview

Neon explains why it built app.build as an open-source reference architecture for AI-native systems. The project demonstrates how agents can generate complete applications with backends, databases, testing, authentication, CI/CD, and deployments, addressing the limitations of code-generation tools that focus mainly on compiling code or rendering components.

## Source excerpt

LLMs are fantastic at code generation. They can produce hundreds of lines of code, entire functions and components, that compile perfectly, implement complex algorithms elegantly, and even follow best practices for style and structure. They suck at full-blown software generation,...
