# Upgrade to Flow from Frames

Upgrade your Frames integration to Flow. Flow is Checkout.com's pre-built, customizable payment user interface that offers a more flexible, scalable, and feature-rich integration.

With Flow, you can use over 20 additional payment methods from a single integration. These include global methods, like Apple Pay, Google Pay, PayPal, and Klarna, and regional payment methods, like Alipay, KNET, and Tamara.

To reduce chargebacks and fraudulent activity, Flow has built-in fraud detection using the [Risk.js](https://www.checkout.com/docs/developer-resources/sdks/risk-sdks/risk-js-sdk.md) package.

Flow also helps to protect your business and reduce the compliance management burden for evolving regulatory requirements. For example PSD2 and PCI DSS.

Flow offers the following performance improvements:

- Dynamic payment method sorting and filtering
- Smart defaults
