The Monolith is Dead

WordPress powers 40% of the web. It is also the #1 target for hackers. It is slow. It is bloated. It is a monolith in a microservices world. Headless CMS (Sanity, Contentful, Strapi) decouples content from code. It allows you to ship omnichannel content to Web, App, and Watch from one source.

The Hidden Cost of Scale

WordPress plugins are technical debt with interest. Every plugin slows down your DB query. Every update breaks a template. With Headless, you pay for the API. You specifically build the frontend. No bloat. No 'Plugin Hell'. Just pure, raw performance.
