# Checkout Extensions Overview

Enhance your Shopify checkout with native extensions that boost conversion and trust

Last updated: 2025-01-16

**Checkout Extensions** are native Shopify checkout customizations that appear seamlessly within the checkout flow. Unlike third-party widgets or scripts, these extensions use Shopify's Checkout UI Extensions API to render directly in the checkout, ensuring fast performance and a native look and feel.

##### Shopify Plus Required

Full checkout extensions require Shopify Plus or Checkout Extensibility access. Some features may be limited on standard Shopify plans. [Check requirements →](https://chargezen.com/docs/checkoutos/getting-started/requirements)

## What Are Checkout Extensions?

Checkout extensions allow you to add custom functionality to specific areas of the Shopify checkout without disrupting the core checkout experience:

*   **Native rendering** — Extensions render as part of Shopify's checkout UI
*   **Secure** — Run in a sandboxed environment for PCI compliance
*   **Fast** — No external scripts or iframes to slow down checkout
*   **Mobile-optimized** — Automatically responsive on all devices
