Creator and commerce decision
BigCommerce
A single developer can build a useful, self-hosted storefront and checkout workflow, but reproducing BigCommerce’s scale, ecosystem, multi-storefront/B2B features, and enterprise services is impractical—keep the SaaS for those needs.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Basic public storefront + product catalog management + cart/checkout + payment processing + order storage and admin UI.
What it still won’t have
- Hosted scaling, uptime SLAs and enterprise-grade compliance
- Built-in marketplace/channel integrations and Feedonomics enrichment
- 1,200+ app ecosystem and one-click extensions
- Multi-storefront, B2B portals, advanced promotions and approvals
- Dedicated support, migration services, and launch/consulting services
What remains hard
- Brand trust
trusted by brands across B2C and B2B.

Paying is—cheaper in year one.
On cash alone, building overtakes the subscription at 1 seat.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal ecommerce store using Next.js (React) frontend, Node.js/Express backend, and Postgres. Core features in scope: product import CSV, product CRUD admin, public product pages, search/filtering, cart, Stripe checkout integration, order persistence, transactional emails, and simple theme CSS. Out of scope: multi-storefront, advanced B2B portals, marketplace integrations, and an app marketplace. Include input validation, error handling, unit tests for backend routes, and deployment scripts for Vercel and a managed Postgres instance.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
