# Stripe Payment Link for $0 Signups

For a free trial or limited beta, use a Stripe Payment Link instead of a checkout session.

## Create the Payment Link

1. **Stripe Dashboard** → Products → Add product
   - Name: e.g. "Atlas Instance (Free)"
   - Price: $0 one-time (or $0/month subscription)
   - Save

2. **Payment Links** → Create payment link
   - Select the $0 product/price
   - After payment: "Customer goes to a page on your website"
   - URL: `https://bc.a250.ca/success?session_id={CHECKOUT_SESSION_ID}`
   - (Use your actual `APP_URL` + `/success?session_id={CHECKOUT_SESSION_ID}`)
   - Create link

3. **Configure ss-atlas** via environment:
   ```
   STRIPE_PAYMENT_LINK=https://buy.stripe.com/your_link_id
   MAX_SIGNUPS=10
   ```

## Behavior

- Landing page shows "Sign Up Free" button → Payment Link
- Limit enforced at: landing, checkout form, success page, webhook
- Set `MAX_SIGNUPS=0` to disable limit
