It's Not Working

"Couldn't detect your dev setup"›

Vibecheck doesn't recognize your project type yet. Click "Ask Claude to help" — Claude will look at your project and set it up for you.

Nothing happens when I click›

Your site might already be running. Check if a browser tab already opened, or look for your site at localhost:3000. Still nothing? Click Preview again — if there's an error, you'll see "Ask Claude to help" appear.

My site looks wrong or shows an error page›

This is usually a code issue, not a Preview issue. Ask Claude in your terminal: "My site is showing an error, can you help?"

I see a message about "port" or "address in use"›

Another program is using the same spot your site needs. Click "Ask Claude to help" — Claude can find what's blocking it and fix it.
