Why Platforms Look for Stripe Connect Alternatives
Stripe Connect is an excellent product. It's well-documented, developer-friendly, and handles the complexity of marketplace payments elegantly. For many platforms, it's the right starting point.
But starting points aren't always endpoints. Platforms look for alternatives when they hit one or more of these walls:
PSP Lock-In
Every merchant on Stripe Connect processes through Stripe. If an enterprise customer has a Worldpay contract with negotiated rates, you can't support them. Stripe is both the infrastructure and the processor.
Geographic Gaps
Stripe lists 51 countries and regions, some in preview, and coverage varies. Some markets have limited features, restricted Connect support, or no cross-border payout capability. Platforms expanding into Southeast Asia, Africa, or parts of Latin America hit limitations.
Channel Constraints
Stripe covers online checkout, Payment Links, in-person payments and agent-keyed phone (MOTO) payments on request, and its Agentic Commerce Suite serves AI commerce. What it does not offer is keypad card capture inside a live call, for a person or an AI agent. Platforms that need it add a voice payment provider on top of Connect, with a separate PCI surface.
Pricing at Scale
At high volumes, Stripe's standard pricing adds up: in the US, 2.9% + 30¢ per card payment, and if your platform handles pricing, $2 per monthly active account and 0.25% + 25¢ per payout. Platforms processing tens of millions want interchange-plus pricing and more control over payment economics.
PayFac-Lite Complexity
Custom Connect accounts make the platform responsible for significant operational aspects: onboarding, compliance, support, and risk management. As regulatory requirements evolve across jurisdictions, this compliance surface area grows.
What to Evaluate in an Alternative
Before comparing specific alternatives, clarify what you need:
PSP flexibility: Do your merchants need to use specific gateways? If yes, you need PSP-neutral infrastructure, not another single-PSP solution.
Channel coverage: Do you need voice, payment links, or AI agent payments, or just checkout? This filters out many alternatives immediately.
White-label: How important is it that payments look and feel like your product, not a third party's?
Speed to market: Are deals waiting? If they are, pre-built components matter.
Compliance: How far do you want to limit your PCI scope?
The Alternatives
1. Adyen for Platforms
What it is: Adyen's solution for platforms and marketplaces, with sub-merchants onboarded and processing on Adyen.
Strengths:
Strong global acquiring coverage, especially in enterprise
Unified commerce (online + in-store on one platform)
Good multi-currency and local payment method support
Enterprise-grade infrastructure
Limitations:
Same single-PSP problem. Adyen for Platforms means using Adyen as the processor. You've swapped Stripe lock-in for Adyen lock-in.
Enterprise-focused, and less accessible for mid-market platforms
Developer experience less polished than Stripe's
Corporate, sales-led process (not self-serve)
Best for: Enterprise platforms committed to Adyen as their sole processor, especially those needing unified commerce (online + POS).
2. Payment Orchestration (Primer, Spreedly)
What it is: Middleware that routes transactions across multiple PSPs. Gives you multi-PSP connectivity, failover, and tokenisation through a single integration.
Strengths:
Multi-PSP routing and failover
PSP-agnostic tokenisation (especially Spreedly's vault)
Smart routing for authorisation rate optimisation
Primer: visual workflow builder, no-code routing rules
Spreedly: deep vault infrastructure, 140+ connections
Limitations:
Merchant-facing, not platform-facing. These are tools for merchants to optimise their own payment stack, not tools for platforms to embed payments for their merchants.
No white-label merchant onboarding or portal
No in-call voice capture; payment links and agentic payments vary by vendor
You still need to build onboarding, reporting and merchant management yourself
Best for: Large enterprises that already have PSP relationships and want to optimise routing between them. Not a like-for-like Stripe Connect replacement for platforms.
3. PayFac-as-a-Service (Payrix, Finix)
Strengths:
More control over merchant underwriting and pricing
Faster than building PayFac from scratch
Limitations:
Still typically single-PSP. Most PFaaS solutions process through a single acquirer.
Some compliance obligations remain, depending on the tier
Regulatory burden scales with your merchant base
No in-call voice capture; payment links and in-person payments vary by provider
Best for: Platforms where payment revenue is a primary business model and you want maximum margin, and you're willing to accept the compliance overhead.
4. PSP-Neutral Payment Layer (Shuttle)
What it is: A payment layer that embeds multi-PSP payment infrastructure into your platform. White-label checkout, merchant onboarding, management portal, and multi-channel support, all through a single integration.
Strengths:
PSP-neutral: 40+ gateways. Merchants choose their PSP or you assign one. Enterprise customers with their own Adyen, Checkout.com or Worldpay Access account can connect it.
Multi-channel: Embedded checkout, voice payments, payment links, chat, and AI agent payments, all through the same integration.
White-label everything: Checkout, onboarding and merchant portal are branded as your platform.
Certifications: PCI DSS Level 1 + ISO 27001 + SOC 2. Card data never touches your platform, which limits its PCI scope.
Pre-built components: not a build project.
Limitations:
No transaction-level routing optimisation, which dedicated orchestration platforms offer
Newer entrant, with smaller brand recognition than Stripe or Adyen
Best for: Platforms that need to embed payments for their merchants, support multiple PSPs, and go live quickly, without becoming a payments company.

Making the Decision
Stay with Stripe Connect if:
All merchants are happy with Stripe processing
No enterprise customers require alternative PSPs
You don't need card capture inside voice calls
Stripe's geographic coverage meets your needs
You're comfortable with Stripe's pricing at your volume
Move to an alternative if:

You want PSP negotiating leverage
Stripe's pricing doesn't work at your scale
You need deeper white-label control
FAQ
Can I migrate from Stripe Connect without disrupting existing merchants? You can run Shuttle alongside Connect and put new merchants on Shuttle. Shuttle cannot connect your Connect platform account; merchants with their own Stripe account and API key can connect it to Shuttle. Saved cards stay with the gateway that stored them.
What happens to my Stripe-tokenised cards? Card tokens in Stripe's vault are Stripe-proprietary: they can't be used with other processors directly. Shuttle has no vault of its own: cards are tokenised with the gateway that processes them. For existing card-on-file customers, you can ask them to re-enter their card details on the new gateway, or keep those customers on Stripe.
Is Stripe Connect really "locked in"? Yes, architecturally. Every Connected Account processes exclusively through Stripe's acquiring network. There's no multi-PSP option within Connect. Stripe's business model depends on being the processor, not just the infrastructure.
What about Stripe's Agentic Commerce Suite and x402? Stripe's Agentic Commerce Suite helps businesses sell through AI agents. x402 is a protocol created by Coinbase for internet payments in stablecoins, which Stripe supports. Both serve online, agent-initiated commerce. For platforms where AI voice or chat agents need to capture a customer's card inside a conversation, in a PCI-compliant environment, that is what Shuttle does.
Outgrowing Stripe Connect? Shuttle gives your platform 40+ PSPs through a single integration, with white-label checkout, voice payments, payment links and AI agent support. Enterprise customers can bring their own gateway if it is one of the 40+. Shuttle is PCI DSS Level 1, which limits your PCI scope.
