Already on WordPress? WooCommerce is free to licence; budget for hosting and paid extensions instead.
Want a custom storefront and full control of checkout? Medusa (TypeScript) or Saleor (GraphQL), self-hosted.
Already have a site you like? Snipcart adds a cart to it without a migration.
Selling digital products with no monthly budget? Gumroad charges nothing until you sell, then takes a flat cut.
Compare transaction fees, not just plans — a percentage of every sale overtakes a $39 plan quickly.
