Shoprocket

Shoprocket is an embeddable shopping cart that adds checkout to any existing website with a simple JavaScript snippet, processing payments through Stripe without requiring you to manage your own payment infrastructure. It supports digital product sales with instant automatic delivery, making it practical for courses, ebooks, and downloadable materials.

Best for course creators on non-traditional platforms, custom websites, or CMS systems that lack built-in commerce. The lightweight embed keeps you on your own domain throughout purchase, and the instant digital delivery works well for immediate course access or materials upon sale.
