Difference between v0 preview and vercel deployment

v0
1

Hey there,

I’m currently trying out to build a quick prototype for a small form which works great so far with v0.
Then I wanted to deploy it to vercel via the deploy button in the top right, but the final deployment seems to not generate the same output I see on the v0 preview.

I’m using the Calendar component with ‘de’ (German) locale, and it seems to result in broken style on Vercel.

V0 output:

Vercel output:

Even after giving v0 the screenshot it is not able to fix the issue.
Has anyone an idea?
Do I maybe need to add custom configurations?

Thanks in advance

EDIT:
So far I figured out:

  • When downloading the generated files and I copy the components/ui/calendar.tsx into components/ and use that, I get the same wrong design as on the vercel deployment. So there seems to be a difference between the generation ui folder in v0 and the downloadable project files

Hi, @dern3rd! Welcome to the Vercel Community :wave:

Could you share a v0 chat with us to try and replicate? I’ve got a few projects on v0 and haven’t seen this :eyes:
