# Introduction
> Build custom storefront templates with the Komerza client library
## What is Storefront Development?
Komerza lets you build fully custom storefronts using any web technology you prefer. Create your store with HTML, CSS, and JavaScript-or use frameworks like React, Vue, or Svelte-and host it directly on Komerza's infrastructure.
Your storefront imports the **Komerza Client Library**, a lightweight script that handles all the e-commerce functionality:
* **Store & Products** - Fetch store info, products, variants, and reviews
* **Shopping Cart** - Manage cart state, quantities, and selections
* **Checkout** - Create orders and redirect to hosted payment pages
* **Analytics** - Automatic tracking for views and conversions (no code required)
## Why Build on Komerza?
No templates or themes to fight against. You control every pixel.
The client library handles all API communication. Just HTML, CSS, and JS.
Deploy to Komerza infrastructure or list on the theme marketplace.
Static files load instantly with global CDN delivery.
Your storefront stays online under any load. Built on Cloudflare for
unmatched resilience.
Every change and deployment is automatically backed up. Store up to 20
backups on selected plans to keep your storefront code safe.
## Quick Example
```html theme={null}
My Store
```
## Theme Marketplace
Build storefronts that other Komerza merchants can use. Your templates can be:
* Listed on the theme marketplace for other stores
* Customized with configuration options
* Deployed instantly by merchants
* Monetized through the marketplace
## Client Library vs API Reference
| | Client Library | API Reference |
| -------------- | ---------------------- | -------------------- |
| **For** | Customer storefronts | Store management |
| **Auth** | Public (store ID) | Private (API keys) |
| **Runs** | Client-side (browser) | Server-side |
| **Operations** | Browse, cart, checkout | Full CRUD, analytics |
The client library is for **customer-facing** storefronts. For admin
operations like creating products or managing orders, use the [API
Reference](/api-reference/introduction).
