stripekit

Adding subscriptions to your app

Stripe, by hand≈ a day · fingers crossed

✕ Create every product and price by hand in the dashboard
✕ Paste fragile price_1Qx… IDs into your code
✕ Write the checkout, webhook, and billing-portal code yourself
✕ Get the webhook logic exactly right — or silently break who has access
✕ Redo it every time you change a price
✕ Cross your fingers and ship

With stripekit≈ 2 minutes · done right

✓ Write your plans in one small file
✓ Your app never touches a price ID again
✓ Checkout, webhooks, and the customer portal — generated for you
✓ The webhook logic everyone gets wrong: written correctly
✓ Change a price? Edit the file, run one command
✓ Real Stripe code that lives in your repo — yours to own

📦

Catalog as code

Declare products, prices, and feature entitlements in stripe.config.ts. `plan` shows a terraform-style diff; `push` reconciles your account to match.

🔑

Your Stripe, not ours

Not a merchant of record, not a hosted control plane. Plain Stripe underneath, state in your own database, nothing to depend on at runtime.

🪝

Correct-by-construction webhooks

The generated handler verifies signatures, dedupes events, and funnels everything through one sync function — so out-of-order delivery can't corrupt your state.

♻️

Idempotent & immutable-safe

Prices are replaced, never mutated; removed items are archived, never deleted. Apply a plan, re-plan, and you get zero changes.

🎚️

One config, test and live

The same file targets test and live mode. `push --live` promotes your catalog, which is what kills test/live drift for good.

🤖

Human- and agent-ready

Deterministic commands with `--json` and `--yes`. An AI agent runs the exact same three commands you do — and can't hallucinate a webhook handler.

# 1. Scaffold config + billing code into your Next.js app npx stripekit init # 2. Preview what will change on your Stripe account npx stripekit plan # 3. Create the products, prices, webhook, and portal npx stripekit push

Your catalog, as code

// stripe.config.ts
import { defineConfig } from 'stripekit'

export default defineConfig({
  products: {
    pro: {
      name: 'Pro',
      prices: {
        monthly: { amount: 2000, currency: 'usd', interval: 'month' },
        yearly: { amount: 19200, currency: 'usd', interval: 'year' },
      },
      features: { seats: 5, projects: 'unlimited' },
    },
  },
  portal: { cancellations: true, planSwitching: true },
  webhooks: { path: '/api/stripe/webhook' },
})

Change an amount, run stripekit push, and stripekit creates the new price, moves the lookup key onto it, and archives the old one — your checkout code never changes because it references the stable lookup key, not a price ID.
