DDD matters more when AI writes your code
Domain-Driven Design matters more when AI writes your codeAugust 20, 2026Miłosz SmółkaCo-founder of Three Dots Labs. Author of Go With The Domain.Whatever you think of AI coding, the way we build software is changing. Everyone wonders, “What will stay relevant?” All we have is opinions, so here’s mine: most ideas behind Domain-Driven Design are now more relevant than ever, as DDD has never been strictly about code.

Everyone wonders, “What will stay relevant?” All we have is opinions, so here’s mine: most ideas behind Domain-Driven Design are now more relevant than ever, as DDD has never been strictly about code. As we do more coding with agents, we still need to understand the domain, model it well, and work as a team. Let’s see what DDD can still teach us and what AI can’t replace.The usual disclaimer: I write about complex projects maintained over months or years, where teams tend to struggle and where DDD shines.
