PayKit is an open-source embedded billing framework for TypeScript applications that lets you define plans, features, and metered usage in code. It runs inside your app, keeps billing state in your own database, and handles the Stripe lifecycle including verified webhooks, subscriptions, and entitlement checks.

Use cases

• add stripe subscription billing to a typescript saas app
• define pricing plans and features in code instead of dashboards
• implement usage-based metered billing with limits and resets
• handle stripe webhooks reliably with deduplication and database sync
• gate features behind subscription entitlements
• avoid vendor lock-in from hosted billing platforms

When to choose

• you use Stripe and want a type-safe, code-first billing layer inside your own app
• you want billing state in your own Postgres database, joinable with your tables
• you need metered usage billing, entitlement checks, and webhook handling out of the box
• you prefer open-source over hosted billing platforms that own your data

When to avoid

• you use a payment provider other than Stripe, since PayKit is built for Stripe
• you want a fully hosted billing solution with a managed dashboard and no code
• your stack is not TypeScript/Node.js
