What does an open source DTC ecommerce platform cost compared to Shopify Plus or BigCommerce?

Spree Commerce is free and open source software, with zero transaction fees, zero platform revenue share, and no per-store licensing for the Community Edition. DTC brands pay only for their hosting, development team (in-house or agency), and an Enterprise Edition license if they need one. Shopify Plus and BigCommerce charge platform fees that scale with revenue, which Spree Commerce eliminates entirely.
