In a previous post, I shared how I built a simple SaaS dashboard using v0 in under an hour. It was a classic “vibecoded” prototype: a quick hack that worked on my local machine, looked great, but relied on manual CSV uploads and had zero security.
It was a proof of concept, not a product.
To take it to the next level, I needed to move beyond the “vibe” and build something robust enough for others to see. Here is how I turned that quick prototype into a serious project.
The Goal: Hardening the Stack
A prototype is fine for testing an idea, but for a “real” app, I had a specific checklist:
- Deploy online: Others on my team should also be able to use it.
- Live Data Connection: Instead of manual CSV uploads, the app needed to connect directly to Supabase.
- Workflow Migration: I wanted to move the codebase from the v0 web interface into Cursor to have full control over the development process.
The Transition: From v0 to Cursor
Since the project was already synced with GitHub, the transition was seamless. I opened the repository in Cursor and started prompting the AI with my specific upgrade plans.
The beauty of this modern workflow is that I didn’t have to manually “wire” everything. I simply dropped the requirements into the chat: “I want to add authentication with Google and replace the local data fetching with a direct connection to Supabase“
It took roughly two hours to implement these changes.
Deployment and Results
Because the project was already set up on Vercel, deployment remained straightforward. Once I pushed my changes to GitHub, the production-ready version was live.
What changed?
- Identity: The app now requires a Google login, giving it a professional entry point.
- Automation: Data is no longer static. It connects to Supabase and shows real-time-data.
- Scalability: v0 is a powerful web-based builder, but moving to Cursor allows me to add more complex features in the long run.
The Takeaway
The gap between a “quick hack” and a “serious project” is shrinking. What used to take days of manual configuration (Auth, Database, Environment Variables) now takes a couple of hours of guided AI iteration.
If you have a “vibecoded” project sitting on your hard drive, don’t let it stay there. Tools like Cursor and Supabase make it possible to up-level your project fast.
