# Headless Guest Experience

### Headless · Developer API

Your interface. Our engine.

Keep the front end you've already built — your app, your site, your kiosk, your brand — and power it with HolidayHero's guest-experience backend. Stays, guidebooks, upsells and the AI Concierge, all over a single GraphQL API.

## Band

You keep the front end and the brand. We run the stay underneath it.

### What is headless?

### Front end and backend, cleanly separated.

"Headless" means the guest-facing interface is decoupled from the engine that powers it. You own and design the experience; HolidayHero handles the heavy backend — guest data, content, payments and AI — and serves it through an API.

No backend to build or maintain, no inconsistent branding, and the freedom to ship and adapt fast.
