# Getting Started

> Build with Supertab in the browser

Use Supertab.js to launch [experiences](/supertab-js/experiences/starting-experiences) or build
[purchasing flows](/supertab-js/reference/overview) for your customers.

Supertab.js provides authentication, logic for purchasing & payments, and entitlement management in your customer's browser.
We recommend using Supertab.js over direct integration with the Customer API for most use cases.
