An open source payments switch to make payments fast, reliable and affordable

Title: Hyperswitch: An Open Source Payments Switch for Developers

Intro

If you've ever built an app that needs to process payments, you know the drill. You pick a provider, integrate their SDK, and then you're locked in. If their rates go up or their API goes down, you're stuck. What if you could connect to dozens of payment processors through a single, unified API?

That's the idea behind Hyperswitch, an open-source payments switch that aims to make payments not just fast and reliable, but also genuinely affordable and flexible.

What It Does

In simple terms, Hyperswitch is a smart router for your payments. Instead of your application talking directly to one payment processor like Stripe or Adyen, it talks to the Hyperswitch server. Hyperswitch then takes your payment request and intelligently routes it to the best possible payment processor in its network.

Think of it as a universal adapter for the world's payment gateways. It abstracts away the unique APIs, authentication methods, and webhook structures of different providers, giving you one consistent interface to work with.

Why It's Cool

So, why would you add another layer to your payment stack? The benefits are pretty compelling:

• Avoid Vendor Lock-in: This is the big one. With Hyperswitch, you're no longer tied to a single provider. You can add or remove processors without changing your core application code. This gives you incredible negotiating power.
• Intelligent Routing: You're not just getting redundancy; you're getting smart redundancy. You can configure routing rules based on cost, success rates for a specific region or currency, or even latency. Send most transactions through the cheapest provider, but route high-value transactions through the one with the highest success rate.
• Improved Reliability: If your primary payment processor has an outage, Hyperswitch can automatically failover to a backup provider, keeping your checkout process alive.
• Unified API and Data: Get a single, consistent API response and a unified data model for all your payment reporting, no matter how many processors you use underneath.
• It's Open Source: You can host it yourself, inspect the code, and contribute. There are no hidden costs or black-box magic.

How to Try It

The easiest way to get a feel for Hyperswitch is to check out their live demo and documentation.

1. Explore the GitHub Repo: The project is hosted on GitHub at github.com/juspay/hyperswitch. The README is a great starting point.
2. Run it with Docker: The quickest way to get a local instance running is using Docker. The repo provides a docker-compose.yml file to spin up the entire stack, including the Hyperswitch server and a PostgreSQL database, with a single command.
3. Check the Docs: For detailed setup, configuration, and API reference, head over to the official Hyperswitch Documentation.

Final Thoughts

As developers, we're naturally skeptical of adding complexity. But Hyperswitch seems to solve a real problem—vendor lock-in—in an elegant way. For a new project, integrating with Hyperswitch from day one could be a strategic move, future-proofing your payment infrastructure. For an existing application, the migration might be a considered decision, but the payoff in flexibility and cost control could be significant.

It's a project worth keeping an eye on, and given that it's open source, it's a great opportunity to see how a complex system like a payments switch is actually built.
