# BigCommerce vs Shopify: Which Can You Vibe Code?

**Verdict: BigCommerce is the easier vibe code** — 18/100 (Don't bother) vs 12/100.

| | BigCommerce | Shopify |
|---|---|---|
| Vibecodeability | 18/100 | 12/100 |
| Tier | Don't bother | Don't bother |
| Estimated effort | 6+ months of full-time work for a crippled single-store subset | 6+ months of full-time work for a crippled subset |
| SaaS bill replaced | $39/mo to $399+/mo | $29/mo |
| Category | E-commerce SaaS | E-commerce & SaaS |

## The case on BigCommerce

Do not attempt to clone the entire SaaS infrastructure; instead, build a single-store headless catalog manager if you need a custom commerce playground.

Hardest parts:

- Building a multi-tenant database architecture supporting store isolation and custom rules
- Designing resilient REST and GraphQL APIs with robust versioning and auth scopes
- Implementing PCI-DSS compliant secure checkout without payment data leakage
- Handling real-time inventory synchronization and concurrent multi-item cart calculation

## The case on Shopify

Build a personal single-tenant portfolio storefront instead, but keep paying for Shopify if you want a real commerce business.

Hardest parts:

- Level 1 PCI-DSS compliance requirements for raw card handling and tokenized payments
- High-concurrency inventory locking and race-condition handling during flash sales
- Multi-tenant data isolation and performance sharding across millions of store databases
- Sandboxed, secure plugin and app ecosystem runtime with strict API rate limiting
- Real-time omnichannel synchronization across web, mobile, and point-of-sale hardware
