# Host overview

Host is Mobly's registration and event-page builder. When you're running a hosted event with formal registration — invitations, ticketed RSVPs, customized event pages — Host is where you build and send those.

For lead capture at the event itself, you'll still use [The Mobly App](/help-center/the-mobly-app/the-mobly-app.md) to scan badges. Host handles the pre-event side (registration, communication) and ties back to your Mobly event so guests, leads, and reporting stay connected.

> **Guests in Host = Leads in Mobly.** You don't manage a separate guest list inside Host — that's replaced by Mobly's leads. See [The Mobly App](/help-center/the-mobly-app/the-mobly-app.md) for capture and [The Hub](/help-center/the-hub/the-hub.md) for lead management.
