How to vibe code a backend with CMS, login, and auth in 20 min (Cursor AI + Supabase)

Learn how to build with AI 🚀 Join our community: https://go.gritai.studio/gritai-vibe-...

In this episode of Build with Cursor, we’ll add a dynamic, editable content feature (CMS) to our app—vibe coded entirely with AI.

You’ll learn how to:
Create a structured content table in Supabase
Build both public and admin CMS interfaces in Next.js
Add role-based access (admin vs regular users)
Protect your data with Supabase RLS policies
And even generate sample data using ChatGPT or Claude

Whether you're building a fitness tracker, a blog, or your next big SaaS—this workflow applies to you.

All without writing a single line of code yourself.
