Adyen vs Spreedly
Adyen ($1,180/mo/mo, vibe code 3/10) vs Spreedly ($2,500/mo/mo, vibe code 3/10). Spreedly is the easier one to rebuild yourself — here is what you lose either way.
Payments
$1,180/mo/mo
- MVP
- 2-3 weeks (for a simple API wrapper around existing acquirers)
- Full replacement
- 10+ years (requires banking licenses and scheme acquirer memberships)
Payments
$2,500/mo/mo
- MVP
- 3 weeks (without PCI scope or gateway coverage)
- Full replacement
- Never fully replaceable due to PCI DSS Level 1 audit requirements and card token migration constraints

our call
Start with Spreedly — highest vibe code, weakest moat.
Adyen
Adyen is an enterprise financial infrastructure provider holding full banking licenses and direct scheme acquirer status globally. You cannot replicate card network connectivity, regulatory compliance, local acquiring rails, and physical POS hardware integration with AI code.
you can rebuild
- Unified API schema for initializing web checkouts.
- Basic card tokenization and iframe UI components.
- Rules engine for payment routing based on country or currency.
- Webhook payload parsing and status aggregation dashboards.
- Basic payment method selection UI (iDEAL, Klarna, Apple Pay wrappers).
what you lose
- Direct Interchange++ pricing models that pass true card cost savings through to large merchants.
- Local acquiring licenses in 30+ markets that boost card authorization rates by 2-5%.
- Omnichannel transaction unification across e-commerce backends and physical terminal fleets.
- Zero-dependency financial rails (Adyen does not rely on third-party processor banks).
- Enterprise risk engines (3D Secure 2 authentication and dynamic exemption management).
real moats
- Full banking licenses in Europe, the US, Singapore, Australia, and Brazil.
- Direct acquiring connections to card networks, bypassing legacy intermediary processor markups.
- Local entity acquiring in 30+ countries, allowing high card approval rates without cross-border declines.
- In-house built unified code base spanning online checkout, in-person POS hardware, and unified reporting.

Spreedly
While routing logic across multiple gateways is easy to program, maintaining a PCI DSS Level 1 compliant card vault is legally and technically prohibitive for in-house agent builds. Additionally, continuously maintaining normalized integrations across 100+ payment processors creates an ongoing engineering tax.
you can rebuild
- Conditional gateway routing logic based on currency or location
- Automatic transaction retries on specific payment failure codes
- Unified dashboard for cross-gateway transaction reporting
- Standardized JSON payload wrapper for transaction requests
- Basic secondary gateway failover logic
what you lose
- Independent PCI DSS Level 1 compliant card vault (storing PANs off-gateway)
- Pre-built maintenance and normalization for 100+ global gateway APIs
- Network tokenization provisioning through Visa VTS and Mastercard MDES
- Automated Account Updater for refreshed card expiration dates
- PCI-to-PCI secure card export protocols when migrating providers
real moats
- PCI DSS Level 1 security certification and hardware security module (HSM) infrastructure
- Token vault lock-in requiring formal PCI-compliant migration procedures to extract raw PANs
- Engineered normalization layer handling breaking changes across dozens of gateway APIs
