Headless vs monolith — when does migration really make sense

Not every project needs to go headless. An honest decision framework to understand when the cost of complexity is worth the benefit.

A trend is not a strategy

Headless has become a buzzword. Every vendor pitches it as a universal solution. But migrating from monolithic WordPress to a headless architecture costs time, money and introduces operational complexity. Is it always worth it? No.

When it makes sense

It makes sense if: you have multiple output channels (web + app + IoT), you need extreme performance and competitive SEO, you have a technical team capable of managing deploy and CI/CD, you want to decouple release cycles between content and code.

When it doesn't

It doesn't if: the site is near-static, the team is entirely non-technical, there's no budget for devops, current performance is acceptable and no business KPI is penalized by it.

The middle ground

Often the answer is a middle ground: hybrid (WordPress headless + Next.js frontend, or SSG with MDX for blog posts but server-side forms). There's no glory in over-engineering.
