our call
Start with Sylius — 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
open source escape hatches
- Ghost open source
- Paid Memberships Pro open source
Sylius
Sylius is free; what you pay for is the Plus licence, the Symfony expertise and years of hardened cart, promotion and taxation code. An AI can generate a comparable core in weeks, but promotion rules and multi-channel pricing are where custom builds rot.
you can rebuild
- Catalog, taxon tree and product variant/option modelling
- Cart and checkout state machine with address and shipping steps
- Order, payment and shipment records with status transitions
- Admin CRUD screens for products, orders and customers
- Channel-based multi-currency and multi-locale storefronts
what you lose
- A battle-tested promotion engine with rule/action composition
- Symfony ecosystem bundles (workflow, security, messenger) already wired together
- The Sylius Plus features: RMA, multi-source inventory, B2B partner accounts
- A large pool of agencies and developers who already know the codebase
- Upstream security patches and LTS upgrade paths
real moats
- Agency and developer familiarity with the Symfony/Sylius conventions
- Plugin ecosystem covering payments, ERP connectors and marketplaces
- Years of edge cases baked into the promotion, tax and shipping engines
