Juspay Hyperswitch

Prism is a stateless payments library that connects your app to multiple payment processors. You can integrate once and point to any payment processor; add fallbacks for redundancy, switch processors based on routing rules - all by swapping a few lines of code. No sign-up needed. No infra setup needed. Actively maintained within the Juspay Hyperswitch production environment. Apache-2.0 licensed, polyglot ready, with SDKs for Node, Python, Java and Rust.
