Install App ↗
ClaudeAdd a cart and custom checkout.
A small connection. A complete shopping journey.
Connect your store with the Penni Cart loader and add commerce attributes to your website elements. The SDK connects product actions, shopping-cart state, and checkout behavior to your markup.
Use your store-specific installation instructions as the starting point. They describe the elements your chosen product and checkout flows need, so you can integrate against an explicit contract.

Keep your layout, components, and voice.
Your existing website does not need to become a hosted storefront template. Build the product page and checkout around your brand, with responsive layouts and the content your customers need.
For JavaScript frameworks, use the explicit asynchronous installation form and test binding after client navigation. The right integration depends on how your app renders and replaces the DOM.
Spend less time building the back office.
Products, stock, orders, shipping, and discounts are managed through Penni Cart. Your team can update the store while your frontend continues to serve the experience you designed.
Choose the features your store needs, configure them in the dashboard, and verify the resulting purchase flow on your own website.

Before launch, check product variants, quantity changes, shipping coverage, discounts, and payment behavior. Make sure validation and payment errors are visible and understandable.
Test your production origin and mobile layouts as well as your local environment. A copied install prompt can accelerate setup, but it does not replace reviewing the result.
See the installation processQuestions, answered.
Can I add a cart to an existing HTML website?
Yes. The SDK is designed to connect commerce behavior to your website elements. Follow your store-specific installation instructions and test the cart and checkout before launch.
Does Penni Cart replace my frontend?
No. Your website still renders the storefront and checkout interface. Penni Cart supplies the commerce behavior and dashboard behind that interface.
