Open-source alternatives to Stripe

Stripe is a proprietary, closed-source payments platform — you integrate against Stripe's hosted API and pay per-transaction fees, with no option to self-host or inspect the underlying routing logic. For companies that want to avoid depending on a single processor or need to route payments across multiple providers, that closed model is a real constraint.

Hyperswitch is the open-source alternative: a payments switch you can self-host that routes transactions across 50+ providers through one API, rather than locking you into a single processor's infrastructure.

FAQ

Is there a free, open-source alternative to Stripe?

Yes. Hyperswitch is open source and free to self-host, though you'll still need underlying payment processor accounts — it's infrastructure that sits in front of them, not a replacement for a merchant account.

What's the best open-source alternative to Stripe?

Hyperswitch is the best fit if you want to avoid single-processor lock-in and route transactions across multiple providers through one open-source API layer.
