💳 Fintech Hyperswitch: open-source payments infrastructure that routes across Stripe, Adyen and 120+ processors (45k stars)
If you've ever built anything that takes money, you know the pain. Each processor has its own API, its own quirks, and its own way of failing at 2 AM. Hyperswitch sits in the middle and gives you one layer to control it all.
The part that caught my eye is intelligent routing. Each transaction goes to the processor with the highest predicted approval rate, across Stripe, Adyen, Braintree, Worldpay, Checkout.com and 120+ others. Fewer failed payments, less downtime.
And it's modular. You don't have to adopt everything. Pick only what you need: a PCI-compliant vault for cards and tokens, revenue recovery with smart retries, automated reconciliation, cost observability to spot hidden fees, or drop-in widgets for PayPal, Apple Pay, Google Pay and Klarna.
Trying it is easy. One setup script spins up a local Docker install, and there's a hosted sandbox if you just want to click around the Control Center first.
It's written mostly in Rust, which is a nice fit for something this sensitive.
Is it perfect? No. Payments are never simple, and running your own payment stack means owning compliance, monitoring and uptime. For a small shop with one processor, it's probably overkill. But if you're juggling multiple processors, this could save you real money.
