Cursor can:

✔ Read your entire codebase

Step 3: Add Authentication & Database Using Supabase (Best Alternative to Firebase)

 

To handle login, signup, and database storage, use Supabase, the most searched backend tool after Firebase.

 

Tell Cursor:

 

“Create Supabase authentication and generate SQL schema for users, billing, posts, and analytics. Connect everything with Next.js API routes.”

 

Cursor will automatically generate:

✔ Supabase auth setup

✔ SQL schema

✔ CRUD operations

✔ Real-time data sync

Stripe is the #1 searched payment gateway for developers.

 

Tell Cursor:

 

“Integrate Stripe payment gateway for SaaS subscriptions with pricing plans, checkout pages, webhooks, and subscription validation.”

 

Cursor will generate:

✔ Stripe Checkout

✔ Webhooks for billing

✔ Subscription validation

✔ Success & cancel pages

✔ Pricing page components

 

This is critical because “Stripe SaaS integration” is one of the highest-searched queries for startup founders.
