Open-Source Payment Orchestration with HyperSwitch: Complete Guide
Deploy HyperSwitch for multi-PSP payment orchestration. Route payments through Stripe, Razorpay, Adyen — with smart routing, retry logic, and a unified API.
What Is Payment Orchestration?
Payment orchestration sits between your application and payment processors (Stripe, Razorpay, PayPal, Adyen). Instead of integrating each processor separately, you integrate once with the orchestrator and it handles:

Why HyperSwitch
HyperSwitch by Juspay is an open-source payment orchestrator built in Rust:
Our Deployment at TechSaaS
HyperSwitch runs at pay.techsaas.cloud with 5 containers:
1. hyperswitch-server: Core API (Rust, ~120MB) 2. hyperswitch-consumer: Async event processor 3. hyperswitch-producer: Event producer 4. control-center: Admin dashboard (React) 5. hyperswitch-web: Payment SDK (client-facing)
Total: ~260MB RAM.

Key Lessons
1. Use official TOML config: Don't hand-write the config, copy from the repo and patch your values 2. API services bypass forward-auth: HyperSwitch API uses its own API key authentication 3. Database migrations: Run diesel_cli migrations before starting the server
Self-hosted payment orchestration gives you full control over transaction data, no per-transaction fees from the orchestrator layer, and the ability to optimize routing across processors.
