our call
Start with Solidus — highest vibe code, weakest moat.
Memberstack
The visible website memberships loop is buildable, but a credible replacement needs more than the first screen. Memberstack earns its keep through payments, network, compliance, so expect a weekend or multi-day build and a narrower personal scope.
you can rebuild
- Build a narrow website memberships storefront or member area for one creator, using Stripe Checkout and explicit digital-delivery rules.
what you lose
- native apps and community moderation
- fulfilment, email, and affiliate ecosystems
- marketplace discovery and buyer trust
- tax, disputes, payouts, and fraud operations
real moats
- compliance-regulatory
- brand-trust

Solidus
There is no licence to escape. Rebuilding makes sense only if you want to leave Ruby; otherwise you are trading a maintained core for a bespoke one.
you can rebuild
- Catalog, variants and option types
- Cart, checkout and order state machine
- Promotions with basic rules and actions
- Admin interface for orders and products
what you lose
- A maintained upgrade path with a security-conscious core team
- Rails extensions for payments, taxes and reporting
- Free bug fixes from other people's production incidents
real moats
- An active maintainer community absorbing edge cases you have not hit yet
