DeepSeek-R1: Build an AI Powered Full Stack SaaS NextJs App

Having a hard time testing the app? Here are some points that might help:

Clerk - The main thing to test is whether ngrok is running. Run ngrok.exe and here do ngrok http 3000 -> take the URL that ngrok gives for your localhost to the Clerk website. Go to webhooks in the settings (+ add the postfix "/api/webhooks/clerk" to your URL) -> take the webhook secret and add it to the environment variables. Double-check that you have the proper webhook Clerk code, layout.tsx with the Clerk provider wrapped, and that the user you are testing with does not already exist in Clerk.

Is the user getting saved to your Supabase after signing up? If yes, you can proceed with testing Stripe ->

Stripe - stripe.ts in the lib folder and webhooks/stripe/route.ts code are the main things. Then go to the Stripe page -> webhooks (or events, not sure how it is now) -> run the stripe login command in a terminal -> accept the terms on the page so it connects -> run the command in the terminal: stripe listen --forward-to -> save the secret -> and then you can test again.

Usually, I fixed a lot of errors during testing by just correcting a typo (e.g., '/api/webhook/' instead of '/api/webhooks/')

What do you think of building this type of application with bolt or cursor?

New subscriber. How to get hold of you man?

I’d like to know if you have any experience as a developer. If not, how challenging would it be for someone like me, who doesn't have a coding background, to create a SaaS product with multiple features?
