What is a headless CMS?

It's your content brain (like WordPress admin) separated from the body (frontend display). Content via API; build any frontend — SPA, app, whatever.

How do I set up headless WordPress?

Dockerize WP for admin/API. Nginx for static SPA + proxy. Fetch /wp-json/wp/v2/ in JS. Cache client-side. Publish instantly live.

Does headless WordPress improve site speed?

Absolutely — sub-second loads vs. 3-5s. Static shell + API hydrate. 90+ PageSpeed default.
