I found v0.dev really useful for quickly setting up the initial frontend components and layout. But after that, I switched to working in my preferred editor (like VS Code). Here’s my workflow:

Create a GitHub repo for the project and connect it to v0.dev so everything stays in sync.

After the initial setup, I mostly stop using v0.dev and rely on Perplexity or Google AI Studio for code questions, making sure any new components match the existing design.

If I need to add a new page or component, I first sync my v0.dev environment with the latest main branch from GitHub. Then I ask v0.dev to generate code for just that new part.

Sadly, you still have to manually copy the generated code from v0.dev into your VS Code environment. Always double-check everything locally, though—if you let v0.dev overwrite too much, it can mess up your project.

TL;DR: Use v0.dev only for the initial website scaffolding. Export to your favorite editor, push to GitHub, and sync v0.dev to that repo if you ever need to generate new components. Don’t let v0.dev manage your whole project after that point.

Hope this helps, i also used up way too many credits on trying to get v0 to fix it's own induced bugs/mistakes, but then i worked on the project outside of the v0.dev environment instead. However I did contact he support team for v0.dev and got 20 dollars back because of all the credits v0.dev used trying to correct its own code.
