Domain
Your website's address — like gptsters.com.
What is Domain?
A domain is the human-readable address people type to find your site. You rent them for $10-15/year from registrars like Cloudflare, Namecheap, or GoDaddy. Without a custom domain, your Lovable app lives at something like myapp.lovable.app.
A custom domain makes your app look professional and trustworthy. It's one of the first things you should get once your app is ready to share.
In Vibe Coding
Lovable gives you a free subdomain like myapp.lovable.app. To use your own domain, buy one from Cloudflare or Namecheap, then point it to your hosting platform. Both Vercel and Lovable have guides for connecting custom domains.
Example
For example: You buy coolapp.com for $12/year from Cloudflare. You add it to Vercel, update the DNS records, and within an hour, your app is live at coolapp.com instead of coolapp.vercel.app.
