Snipcart

Snipcart lets you add a full shopping cart and checkout system to any website, regardless of your tech stack. It is designed for developers and merchants who want to sell physical or digital goods without rebuilding their site or switching platforms.

• Quick integration: Add a JavaScript snippet to any page to enable a shopping cart. No complex setup or server changes required.
• Works with any platform: Compatible with all site builders, CMSs, and frameworks. Use it with static sites, single-page apps, or traditional websites.
• Sell physical and digital products: Manage physical goods with shipping, inventory, and discount features. Sell digital content like downloads or licenses.
• Developer-friendly tools: APIs and webhooks let you connect external services for tax, shipping, inventory, or analytics. Customize the checkout flow to match your needs.
• Secure and fast checkout: The cart lives on your frontend, so customers never leave your site to complete a purchase. The checkout is streamlined to minimize steps and reduce cart abandonment.

Over 20,000 merchants use Snipcart to add e-commerce functionality to their existing websites. Testing is free with no credit card required.
