Decoupling WordPress with the REST API keeps your editors happy but doesn't fix the security or performance problems a real migration solves. Here's how to decide.

Headless architecture doesn't make a site fast by branding alone — it removes specific bottlenecks: CDN-served pre-built pages instead of per-request server rendering, more crawl budget spent discovering pages instead of waiting on them, and metadata generated programmatically instead of set by hand.

The headless CMS market is projected to grow from roughly $3.94 billion in 2026 to $22.28 billion by 2034. This guide compares the platforms actually leading that market — Sanity, Contentful, Strapi, Storyblok, Hygraph, Payload, Directus, and EmDash — by what each is genuinely best at.
