Скачать или смотреть Add authentication and payments to your web app - Part 1

You’ve built your web app. Now you want to let real users log in and pay for subscriptions. In this video series, I’ll walk you step-by-step through how to integrate authentication with Clerk and set up payments with Stripe.

I’ll be using the AI Headshot Generator I built with Google Gemini’s Nano Banana model as the example project. You’ll see exactly how to:

Add login/signup with Clerk (email + Google)
Gate app usage behind authentication
Give users a free trial (1 free headshot)
Upsell paid plans ($10 packs or $15 unlimited)
Prepare for Stripe integration to manage subscriptions

This is Part 1 of a 2-part series. In Part 2, we’ll connect Stripe for full subscription billing and checkout.

If you’re building SaaS or web apps, this guide will help you put the business side in place—authentication + payments—so you can start monetizing.
