PayLayer is a unified payments SDK for Stripe, PayPal, Paddle, Lemon Squeezy, and Polar.
Integrate billing once, then reuse the same code for one-time payments, subscriptions, billing portals, and webhooks — without provider lock-in.
Once installed, adding billing to any screen takes minutes.
Built for developers who care about clean DX, production-ready payments, and flexibility as their product grows.
