The models' case: Best overall fit for multi-PSP ecommerce because Universal Checkout, processor-agnostic tokenization, visual Workflows, conditional routing, retries/fallbacks. The models' main caveat: Enterprise-oriented pricing and sales process make it hard to justify for smaller merchants or simple two-PSP setups.

strong observability, A/B routing, and a broad connector library make it the most practitioner-friendly way to run truly PSP-agnostic checkout.","fix":"It is an orchestration layer, not a vault or processor — you still contract and manage every downstream PSP/acquirer relationship, and the abstraction adds cost and a dependency you don't control."},{"rank":2,"product":"Spreedly","reason":"The most mature independent option, with the largest catalog of pre-built PSP/gateway integrations (well over 130) and a PCI-Level-1 vault that makes card data portable across processors plus network tokenization — the strongest choice when the priority is avoiding processor lock-in and owning your tokens.","fix":"Vault-and-connectivity DNA means its no-code routing/workflow tooling is less rich than Primer's, and pricing/complexity skew toward higher-volume merchants rather than small shops."},{"rank":3,"product":"Gr4vy","reason":"Cloud-native, single-tenant orchestration (isolated infrastructure per merchant) with solid routing, vaulting, and anti-fraud/PSP fan-out;
