Open‑source payments orchestration for modern SaaS.
PayKit is a TypeScript‑first framework that lets you integrate and operate multiple payment providers through a single, consistent API — without locking your business to any processor.
PayKit orchestrates payments. It does not process them.
Most teams start with a single provider like Stripe. As soon as you expand internationally, add PayPal, or need regional card processors, payments become fragile and hard to maintain.
PayKit exists for teams that:
- Use multiple payment providers
- Operate in multiple regions
- Want control without lock‑in
- Care about correctness and extensibility
- Unified TypeScript API across providers
- Provider adapters (Stripe, PayPal, regional PSPs)
- Card payments with a single form
- Subscriptions (periodic & usage‑based)
- Attach / detach payment methods
- Hosted checkout (self‑hosted, white‑label)
- Internal balance & ledger abstraction
- Webhook normalization
- Plugin & adapter system
- DB‑native (Prisma / Drizzle)
- Next.js‑first developer experience
- ❌ A payment processor
- ❌ A Stripe replacement
- ❌ A closed SaaS you can’t self‑host
PayKit sits between your app and payment providers and gives you a stable, extensible foundation.
You own:
- Your database
- Your UI
- Your dashboards
- Your payment relationships
PayKit is open source and designed to be:
- Inspectable
- Extensible
- Self‑hostable
- Production‑ready
You can build your own dashboards, workflows, and internal tooling directly on top of PayKit.
For teams that want less operational overhead, PayKit Cloud provides:
- Unified admin dashboard across providers
- Reliable webhook ingestion & retries
- Analytics & reconciliation
- Tax & accounting integrations
- Enterprise support & SLAs
Using PayKit Cloud is optional. The core framework will remain open source.
🚧 Early development
Initial focus:
- Stripe adapter
- PayPal adapter
- Core orchestration API
- Plugin system
- Prisma integration
APIs may change.
PayKit is inspired by the developer‑first, adapter‑based approach of the better‑auth project.
