Hyperswitch is an open-source payments infrastructure platform that acts as a smart intermediary between a business's checkout flow and the many payment processors available globally. The core problem it solves is vendor lock-in and fragility in payment systems: most businesses start by integrating a single payment processor like Stripe, but as they grow they need redundancy, cost optimization, and access to regional payment methods, and migrating away from a single processor is painful and expensive. Hyperswitch addresses this by providing a unified layer that connects to over 120 payment processors, Stripe, Adyen, Braintree, Checkout.com, and others, through a single API. Rather than building direct integrations to each, a business integrates once with Hyperswitch and then configures routing rules to decide which processor handles which transaction. For example, you can route low-risk transactions to the cheapest processor, retry failed payments through a backup, or use region-specific processors where success rates are higher. The platform is modular. You can use just the routing and retry logic on top of your existing setup, or adopt the full suite which includes a PCI-compliant card vault (secure payment method storage), revenue recovery tools for failed payments, cost observability dashboards, automated reconciliation, and drop-in widgets for wallet payments like Apple Pay and Google Pay. Someone would use Hyperswitch when building or operating an e-commerce or SaaS business where payment reliability, conversion rates, and processing costs are serious concerns, particularly when operating across multiple countries with different preferred payment methods. The tech stack is Rust, chosen for high performance and reliability. Hyperswitch can be deployed via Docker locally, via Kubernetes with Helm charts on AWS, GCP, or Azure, or tested immediately through a hosted sandbox environment.
