Open Source Payment Orchestrator | Juspay Hyperswitch | WarmIndex

Hyperswitch is an open-source payments orchestrator that connects businesses with multiple payment processors through a single API, empowering developers and enterprises with flexible, scalable payment infrastructure.

🚀 Overview

Hyperswitch addresses the pain points of vendor lock-in, high costs, and complexity in managing multiple payment service providers (PSPs) by offering a modular, composable open-source payments stack.

It is built for developers, engineering teams at enterprises, and large merchants handling high-volume transactions who need control over routing, reconciliation, and optimization without relying on proprietary solutions like Stripe.

Juspay created Hyperswitch to democratize payments infrastructure, making it fast (sub-30ms), reliable (99.999% uptime), and affordable through intelligent automation and global compliance (PCI DSS, GDPR).

Secure Vault for PCI-compliant storage of cards, tokens, and payment data
Revenue Recovery with multi-modal retry engine configured to 30+ parameters to reduce churn
Reconciliation Engine for automated, customizable 2/3-way matching with real-time exceptions
