ACI Payments Orchestration Platform vs OpenSwitch

ACI Payments Orchestration Platform has no write-up on Specifiction yet; its figures are above.

OpenSwitch provides one API for routing, retrying, and observing payments across multiple payment service providers. Routing rules can use cost, success rate, currency, BIN, geography, or custom expressions, while retry policies and connector fallback chains reroute soft declines. A shared schema covers payments, refunds, disputes, mandates, and webhooks across enabled connectors. The product describes a network-token-aware vault with tokens portable across PSPs controlled by the customer. Per-connector latency, authorization rates, and decline reasons are available, with event export through webhooks or S3. The connector directory lists 18 integrations, including Stripe, Adyen, Checkout.com, Braintree, Paymob, Klarna, PayPal, and Razorpay. Developer materials document REST and JSON, an npm SDK, Docker, and a self-hosted Rust binary. OpenSwitch says it does not custody funds; settlements occur directly between PSPs and customers' bank accounts. Open Source is free; Cloud is priced on request per orchestrated request.
